Couch to Cat C, Week 6: The Final Countdown

Our goal: to transform a 265-pound rookie rider with a tested 1.92w/kg FTP into a cat C Zwift racer (2.5w/kg+) in 6 weeks.

The first week was mostly about orientation and baseline testing, the second week about building endurance and improving form on the bike. In the third and fourth weeks we started pushing the endurance Boone was building, working to keep the watts higher over the duration of the ride. And in the fifth week things got tougher, with V02 workouts making their way into the mix.

Now the final week. It would have a bit more VO2 work, plus some racing and testing to measure progress. Would we achieve our goal? Only one way to find out!

The Plan

As a reminder, here’s the basic plan we settled on for the 6 weeks. (Many thanks to Alan Dempsey of HPP Coaching for giving us solid advice that sets Boone up for success).

  • Week 1: Benchmark testing + Endurance
    FTP test, attempt first Zwift race, and get some time on the bike
  • Weeks 2-4: Endurance + Cadence Work
    Lots of work from low zone 2 to mid zone 3, with some high-cadence drills to train the legs for efficient pedaling
  • Weeks 5-6: Endurance + Intensity, Finishing with Benchmark Testing
    Start with similar rides as weeks 2-4, with some VO2 and threshold efforts included in short durations. Toward the end of week 6 we’ll do another FTP test and Zwift race, so we can compare progress from week 1.

Ride #21: VO2 Workout, Aborted

We had high hopes of completing one more tough VO2 workout at the start of this final week, but it didn’t really work out, probably due to several factors…

First, Boone’s FTP had been bumped up from 250W to 257W – so the intervals were at a higher wattage. Then we added 15 seconds to his 3-minute VO2 intervals. He had done an FTP Ramp Test the day before, so his legs might have been feeling that effort still. And on top of that, Erg mode was misbehaving at the start of the workout (a reboot fixed things).

His first 3:15 interval was a struggle. And the second interval took all he had. After that we just binned it, and Boone rode around Yorkshire, enjoying the sights and getting in some saddle time. Today wasn’t the day for a tough effort, but he could still get some riding time in while working on his cadence and endurance.

Ride #22: New Hour PB

We wanted to see how long Boone could hang with C. Cadence, so on Wednesday he headed to Fuego Flats to spin and warm up his legs. Our plan was to hopefully come across Cara’s group after a bit of a warmup, then just hop in and go.

This actually worked out nicely, and Boone was pushing some decent wattage when Cara finally came through. Boone held onto her group for the rest of his hour-long effort, setting new power PB’s in the 23 minutes + range, including averaging 223W for the full hour. He also rode further in this ride than any previous, covering 23.2 miles.

While he rode I logged into Boone’s account in Zwift Companion and handed out Ride Ons to the C. Cadence group, resulting in lots of unlocks (and XP bonuses).

Ride #23: Crit City 8-Lapper

With just a few rides left in his final week, Boone and I were both itching to see him test his newfound fitness. So on Friday, Boone joined an event which he hadn’t tried before: a Crit City 8-lapper (he had only done 6 before), in the Bell Lap direction (he had only done Downtown Dolphin before).

First he warmed up with an easyWatopian spin, and I adjusted his weight down once again. (He’d been watching his calories closely, and enjoyed dropping his in-game weight regularly!)

Dropping Boone’s weight once more – he’s so close to that 235lb target!

Before the event I did a bit of poking around ZwiftPower to survey Boone’s competition. I came across one noteworthy rider: Lukas Reischl. Lukas stuck out on the signup list because he had the best ranking, but when I clicked his profile he really stuck out. Nearly every event in his recent list was a Crit City D race that he had won! (14 races in 2021, 10 of them are 1st place finishes in Crit City).

Now, we could discuss how it’s probably time for Lukas to upgrade to the C’s so he can push himself to new levels of fitness – but that’s a topic for another post. What was important for us was that Lukas seemed to be very similar to Boone. He’s a big dude, with a strong sprint. And he knew how to win. I told Boone, “This is the guy to mark for the race.”

41 D riders started the race, but within the first 2 minutes the front selection was made – and Boone was in it! 7 riders worked to build a gap on the chasers, and the seconds added up.

Boone, sitting in the front group

Boone rode smart, staying in the draft. I handled his powerups, deploying them when it was most helpful. After a few minutes the green cones started showing up, slowing the sandbaggers and thinning the front group further. After just 2 laps, only 4 riders remained in the front group: Reischl (above), Nathan (a ZP-registered rider), “Colvin” (who we knew nothing about), and Boone.

Not much happened in laps 2-7… the gap to the chasers grew, the 4 front riders kept plugging away, and Boone stayed out of the wind mostly.

Giving Boone some sprint tips on the penultimate lap

On the 7th lap, it suddenly hit me that Boone had never sprinted for a win in a Zwift race. Uh oh. And he was going up against Reischl, who clearly knew what he was doing, and had the power to back it up. As we neared the end of lap 7 I tried to talk Boone through the finishing sprint, explaining that it’s usually a mistake to go early. That he’ll want to shift up a gear or two. And telling him where to start the sprint.

Then it was the final lap. All we got was a steamroller powerup, which wouldn’t help us in the sprint – so I used it on the bricks. Nathan tried to go long, and Boone grabbed Reischl’s wheel then Colvin’s as the three chased Nathan. Then Nathan got coned! (Time to move up the C’s, Nathan!)

Nathan (off the front) gets coned

It was just the 3 riders now, and nobody wanted to go first. Boone got to the front and started his sprint. The other two were on his wheel. Colvin couldn’t come around, but cagey Reischl was sitting in with a draft powerup, and in the final straightaway rocketed around Boone to take the win.

Reischl about to come around Boone in the final meters

Boone’s a pretty competitive guy, and he was not happy about losing that final sprint. He wanted a rematch!

But looking on the bright side, we were both happy – he had finally hung in the front pack for the whole race. That’s a huge accomplishment. Just being in the mix for the final sprint is a big deal! Winning that sprint is another matter entirely, of course. It comes down to which powerup you’ve got, how much is left in the legs, a good sense of timing, and more.

This race gave Boone a huge confidence boost, as you can imagine. It also gave him an FTP boost, and an upgraded power curve from 16 minutes onward.

Ride #24: Crit City Breakthrough

After Friday’s race, Boone definitely had the hunger. He was looking for a win. So on Sunday afternoon he came over to take on his third Sunday Crit City race. Just like the previous two Sunday races, it would be 6 laps of the Downtown Dolphin route.

We discussed strategy ideas beforehand, and he said he thought he could break away sooner – perhaps using the brick descent as a launch pad in the final lap. I also gave him a few squirts of my secret weapon – PR lotion. What can I say? We both wanted a win! I warned him that PR lotion, which contains bicarb, would help his legs not burn so bad. But the muscles are still doing all the same work, so he shouldn’t go too hard too early and blow up!

I did a bit of ZwiftPower scouting beforehand, but no riders stuck out like Reischl did in the earlier race. As Boone spun his legs around Watopia to warm up, I dropped his weight further – he had skipped out on birthday cakes and Valentine’s candy, and it had paid off. Sub-235 pounds for the first time in 9 years!

Right out of the gate a gap opened up, and Boone was in the chasing group. This is where you have to make a split-second decision. Do you put in the work to close that gap, or do you ease up, hoping others in your group will do the work for you?

We didn’t leave it to chance. The race had just started, and Boone certainly had a few seconds of high watts in his fresh legs. Close the gap!

And there we were. The selection was made – 8 riders out of the initial 27.

At the top of the bricks on lap 2, 4:40 into the race, RadDadChad got coned. (He’d stuck in out the rider list because of his great name, but also because he had messaged beforehand that he would be winning the race.) Pride goeth before a fall, Chad. 😋 You’ll hear us razzing you in the video below, but it’s all in good fun.

As Boone began the brick climb on lap three, he put in an extra dig as I activated his feather powerup. He and rider “Almanza” quickly gained a 3-second gap on the other 4 riders. Boone went to the front, pushing extra watts on the descent and building the gap.

Was he really going to attempt this? I didn’t say it at the time, but I was thinking, “This is way too early – he’s going to blow up.” Boone dropped Almanza, and built the gap to 10s by the time he crested the brick climb on the 4th lap!

His heart rate was pretty high, but he looked good, and nobody behind was willing (or able?) to put in a real chase. The gap kept growing… at the top of the bricks on the 5th lap he had 12s on them. Could he hold on?

Boone off the front on the penultimate lap

As he began his final lap his heart rate was at 190 – the highest we’ve seen is 192.

But he had that look in his eye. I’ve seen it before, many times. He wasn’t going to stop.

The group behind was trying to chase, closing it to 8-9s. But it was too little, too late. Boone hammered up the bricks as a strong rider from the chase group got coned. Then Boone hit the bottom of the descent, hammered for a few seconds, then stopped pedaling and “coasted” over the finish line, 8s ahead of the closest pursuer!

And even though he stopped pedaling at 19 minutes, he still got an FTP upgrade based on his 20-minute average power. A breakthrough ride for sure!

We checked ZwiftPower for confirmation of his win… but his name wasn’t showing up. Clicking “Unfiltered” we discovered Boone had been disqualified – his w/kg were too high for a D race (2.78 w/kg for 19:01)!

So not an official win (and Boone wanted to be sure to extend congratulations to “Joseph Davis”, who took 1st in ZwiftPower.) But Boone was happy to be DQ’d. Because it meant we had achieved our goal: to achieve a 2.5 w/kg FTP in 6 weeks. To be bumped up into Cat C status. The new FTP (276W) divided by Boone’s weight for today’s race (106.4kg) gave us 2.59w/kg.

Watch the Race Video:

(You’ll hear my wife Monica in there, as well as our very expressive buddy Zane who’s been coming over to watch Boone’s races)

See this ride on Strava >

And the PR Lotion? Let’s just say Boone is convinced. “My legs didn’t hurt at all.” He’ll use it in his final FTP test as well.

Ride #25: Final FTP Test

Zwift had detected an FTP of 276W in Boone’s race, but we wanted to finish the 6 weeks with an FTP test, the same way we’d begun. So the day after his race win, Boone did a ramp test. Could he meet or beat the 276W mark with semi-tired legs?

Yes he could! The ramp test gave him a new FTP of 278W. That gives him a final FTP of 2.62w/kg, up from a starting FTP of 1.92w/kg. A 36% increase. Amazing! His pure wattage went from 230W to 276W, which is a 20% increase.

Confirmation that his “race FTP” was quite accurate

Final Takeaways

I’m super-impressed with that Boone was able to accomplish in 6 weeks. But I’m not surprised.

You see, as close cousins, we’ve known each other since before we could walk. And he’s always been a guy who, once he sets his mind on doing something, gets it done.

He lost over 30 pounds in these 6 weeks, by carefully watching what he ate and getting some exercise every day. And he jumped into every workout I threw at him, never complaining or trying to weasel his way out. He knew we both wanted the same thing – and trust makes a good team. We had a good plan, we stuck to it, and the results followed. That’s how training works.

Post-ride hangout in the office/pain cave

The fitness gains are great to see, but in the end, we both agreed that our favorite thing about this 6-week experiment was how much we got to hang out with each other. We’re best friends, but the daily pull of work, family, etc, means we don’t spend a lot of time together. I think that’s going to change moving forward.

What’s Next?

Boone wants to keep riding, as he wants to keep losing weight until he gets to a healthy 190-200 pounds. He doesn’t have much interest in outdoor riding, but likes the efficiency and safety of indoor workouts. And, of course, he enjoys the competitive aspect of racing!

We haven’t figured out exactly what his Zwift setup might look like yet, but for the next couple weeks he’ll be riding on my setup as we figure out what comes next. Maybe, just maybe, a new Zwift Insider series will emerge! Stay tuned.

Thanks for Your Support

Thanks so much to everyone who cheered Boone on during this 6-week journey. He really appreciated it!

Favero Releases Auto-Calibration Firmware Update for Assioma Pedals

Favero Electronics released a firmware update for their much-loved Assioma power meter pedals which adds auto-calibration functionality.

While I’m a big fan of the Assioma (see my complete review here) due to its accuracy, reliability, and pricing, there is one place where the Garmin Vector pedals had a leg up on Assioma: Vectors can be set to auto-calibrate. Auto calibration is the direction power meters and smart trainers are heading, because there’s really no downside! It helps ensure consistently accurate power numbers and removes one more task from our pre-ride checklist.

I installed the new firmware today, then took the pedals for a spin, dual-recording with my Wahoo KICKR 5 trainer. The resulting power comparison can be seen here on ZwiftPower, with the Assioma pedals averaging just .33% more watts than the KICKR 5. Nice!

Here’s Shane Miller’s take on firmware update, including an explanation of just how the auto-zeroing works:

Upgrading Your Firmware

The firmware update is easy to install via the Assioma mobile app. Once it’s installed, auto-calibration is enabled and you can simply ride without worrying about calibrating. Here are steps on the iOS app:

And here’s a support page from Favero if you need help updating your firmware.

Wrapping It Up

With auto-calibration in place, the Favero’s Assioma pedals are head and shoulders above the competition. Priced at just $720US compared to Garmin Vector 3’s $1000US, the Assioma has features which meet or beat Garmin’s at a significant discount on cost.

My take: Garmin needs to step up their game by reducing pricing or boosting features if they want to remain competitive in the pedal space.

Looking to buy some power meter pedals? I can’t recommend the Assioma platform highly enough! They can be purchased direct from Favero (based in Italy) or at these Zwift Insider affiliate partners:

GeekingWatts – the Virtual TTT Compared to IRL

9

The NYC TTT on Mighty Metropolitan, what a race that was! I went deep into the weeds on the best strategy for this kind of course, read a few articles on good TTT strategy for rolling hill courses in-real-life (IRL), then went back and looked at power profiles of some of the better teams as well as their DS live-streams. 

The video below shows some of this DS live-stream footage of Zwift teams that went for a momentum strategy, which seemed to win out on the day. 

Watch the video:

So, can we use tips for TTTing in real life to help with TTT strategy in Zwift? 

Pull length

IRL the advice is to take longer pulls on uphill segments and shorter ones on descents.  The best teams in the TTT had someone pace up the KQOM, basically taking a 2-3 minute turn at the front.  The longer pull meant less surging on the climb, a pace set that could keep all riders together without blowing anyone up. 

In Zwift, I do not think taking turns on the downhill is the best strategy. The best strategy I saw was teams that built up momentum on the flat at the top of the climb with the heavier rider getting into supertuck ASAP and everyone else falling into their draft.

Pacing a climb

‘The effort going up the climb should be no more than 5 watts higher than on the flat’.  This is an interesting one and there were so many teams who blew up riders on the climb and then haemorrhaged time in the last 9km.  Key was having a watt/kg target for the team up the climb, paced smoothly by the lead rider.

Set order or momentum

Similar to IRL, on a flat course the set order strategy is definitely the best, nice straight line with small gaps between riders.  This enables good recovery time after riders have taken their pulls.  But this was not the best strategy for a rolling/hilly course like NYC. 

The two teams in the video, Saris+TPC men and Finesse women, both followed a momentum strategy.  On the rolling terrain whoever came through with momentum to the front took a turn.  With this strategy, you really need an even power profile between riders otherwise lower power riders will be yo-yoed off the back and burn too many matches surging to get back on.  This strategy also required a really strong DS to clearly call who is in front at what time.

Communication

This is probably the biggest difference between virtual and IRL TTTing.  IRL you use hand signals, you can hear the riders around you, you can hear if people are heavy-breathing and struggling.  On Zwift you see nothing other than a very calm looking avatar, the subtle cues of the riders around you are not there.  This is where the DS in Zwift is vital.  They are the ones who can see everyone’s HR and power data, can see in a bird’s eye view those who may be dropping off the pace, and can keep things calm through clear instructions.  I would recommend any team that does not have a dedicated DS to find someone. It makes probably the biggest difference – even bigger than bike choice!

Hot, Hot, Hot – Tips for WTRL TTT #96 – Volcano Flat

3

For a year I have been obsessed with the weekly Team Time Trial run by WTRL… so I asked Eric if I could share my obsession with you all, in weekly doses.

Each week I will give you a profile of the upcoming route, guidance on bike choice, and some target times if you want to aim for the Premiere League (top-10 in each coffee class get to be in a special race televised on YouTube). 

If you can’t ride (or even if you can ride, but want more action!) tune in to the live TV show on Zwift Community Live’s YouTube Channel at 6:15 (UK time). 

Greater London Flat

Before we look at next week let’s review this week’s performance in London last week

Category#86My prediction#95 PLHow did I do?

I’m pretty happy with that… remember my goal – predict a time that is closest to (but not above) 11th spot in each category. 

Dani Rowe nee King

So how did I do in London? Attentive readers will recall that I am currently riding with the Rowe and King (R&K) Vixens Latte team, having moved from one of the other R&K Latte teams, the Hyenas. This week the Vixens were lucky enough to have some proper cycling royalty in the team – World Champion, Olympic Gold winner, and MBE – Dani Rowe (nee King… do we still say nee or is that old fashioned?) joined us.

Dani is one of Rowe and King’s top coaches, focusing on coaching female riders and, before I hear cries of sandbagging (I know the Zwift racing audience…), Dani is rebuilding fitness after having a baby, and the weekly WTRL TTT is a perfect place for that. 

I have to say I was somewhat overawed to be in the same team as a World Champion, or as Team Captain Trigg put it in his post-race analysis… “At the pre-race sign-on I held back the autograph hunters as our Olympic champion entered the paddock. Sherpa had a selfie with her but he looked crushed when it became apparent that she was unfamiliar with his TTT course reviews. Apart from that, and the return of Gaby, this looked a well balanced team of fit, if ageing, chuggers.”

Trigg was right – R&K Vixens had a blinder of a day around London. Despite the dreaded Ghost Bug (basically the team can’t see me or draft off me) we delivered a time over a minute faster than our target time, coming in 47th of 403 Latte teams… and I hit 3.2 w/k for the ride… a first for me. We are feeling bullish for the Volcano Flat course, that’s for sure!

Thursday 18th February – Watopia Volcano Flat 

We are heading to Watopia again this week with three laps of the Volcano Flat course. This course has been run a few times in the past year and is a popular loop for riders, so I’m sure you have all ridden it before. The course is flat, but much longer than last week – overall it’s 35.5km with 150 meters of climbing. This is going to be another fast and furious day in the saddle. 

Starting in the downtown pens, we head towards Ocean Boulevard and under the sea. Straight ahead at the biosphere T-junction and through the hole in the Jarvis Tree. Pop up above ground, cross the gravel then head up the winding hill, then descend to the Italian Villas. Hard left turn at the fountain, and down the gravel road to the land-bridge which takes you to the Volcano. Take the long way around the Volcano, cross the sky bridge and it’s downhill back into Downtown. Then do it two more times. 

This isn’t a short ride, but it is mostly flat – just a few areas where you will need to pay attention – more on those later. 

What to ride?

Like last week, this is all flatness… so despite the two patches of gravel, aero rules. In our tests (by “our” I mean Eric did the science again) the fastest, aeroest bike – Venge/Super 9 is faster than the Tron bike – around 2 seconds a lap. 

S-Works Venge + 858/Super9 wheels

Here are some recommendations on equipment at various levels:

  • Level 6 Zwift Aero frame and DT Swiss ARC 62 wheels
  • Level 10 Canyon Aeroad 2021 and DT Swiss ARC 62 wheels
  • Level 13 Canyon Aeroad 2021 and Zipp 808s
  • Level 20 Trek Madone with Zipp 808s
  • Level 25 Cervelo S5 with Zipp 808s
  • Level 31 Cervelo S5 with ENVE SES 8.9
  • Level 33 S-Works Venge with ENVE SES 8.9
  • Level 35 S-Works Venge with Zipp 808/Super 9
  • Level 45 get those 858/Super 9 wheels and pair them with the S-Works Venge

As always, the ZwiftInsider reports on frames and wheels are superlative so if you want to find the perfect bike and wheel combo for you, check them out.

While the Tron bike is beaten this week – it is still the number 2 bike on the day… and the bike/wheel combo that beats it can’t be had until level 45… and it is free (the only cost is your sweat). So I cannot stress highly enough that if you are racing you need to be working on Tron. It’ll take a while, but just set the Everest Challenge and forget about it for nine months… like having a baby (just ask Dani). 

Route Recon Rides

You have no excuses for surprises on this course… there are pages of Volcano Flat rides on the event listing on zwifthacks.com. It is even one of the makeup rides for Tour de Zwift Stage 1, this weekend.

Race breakdown 

You can see from the segment map below… there isn’t a single hill worth mentioning…

Downtown ’til you pop out of the ocean

Mostly flat apart from the nice drop under the Ocean cover you for the first 3.5km of each lap. Plenty of time to get into your groove.

From the tunnels to the land-bridge

The challenge here isn’t that this segment is hard – it’s not… but the constantly changing terrain can throw off your formation – and trust me – if you are doing this right, you will be on the rivet the entire time. 

The rather convoluted segment is tricky. It starts with the bump out of the ocean (200 meters at 3%) then heads into some gravel which will slow you down… from there it’s the false flat (1%) up the hill which tightens at the top to 5% for 100M. 

The downhill to Italian Village isn’t enough to supertuck, but it’s enough to pick up speed before hitting more gravel. Just make sure your heavier riders don’t get overzealous and race down the hill away from your lightweights. 

As you come to the Italian Village turn sharp left and down the gravel hill. All this gravel… they really need to fix these roads. 

Around the volcano…

Take the longer way around the volcano – and here is where you hit the only major bump in the ride. The double-bump that takes up up and into the volcano itself. It isn’t long or hard, just 8 meters vertical at 5% – use the teams momentum to get up and over without losing too much momentum… and don’t forget the little 3 meter kicker that comes afterwards. 

Across the sky bridge and down into town 

Down the hill picking up speed as you go. At 8km (and 20.5, 32.5) you will hit some gravel that will slow you down – stay in formation here… then its down into the tunnel under the sea. 

Out of the Sea to the start/finish

Once you get out of the undersea tunnel its a straight shot of 1.3km to the start/finish. 

Target times

Volcano Flat was a TTT course twice last year – in February (#45), in May (#56), then again in July (#63). Interestingly, the faster teams got slower, while the slower teams faster! I think there is going to be a significant jump in performance this time though…

Class#56#63My prediction
Vienna55:5355:2855:00
Doppio47:4448:0647:15

Frappe50:5951:0250:30
Latte54:5454:4254:30
Mocha1:02:231:02:001:01:00

As for the Vixens, we are feeling bullish. We have a strong complement of 8 seasoned riders and didn’t lose any of our stronger riders to the Cheetahs (strong riders often move up a team, weak riders move down). In London we were only a minute off a PL spot… do we have a chance this week? We will find out on Thursday!

Wrapup

Like last week, this is all about getting in formation and staying there. A fast start without having to wait on someone that forgot to pedal, good strong turns and team discipline will determine whether you make the PL… Pick your aero bike… get into your team kit, and I’ll see you in the pens. 

Video: Everything You Need To Know About FTP, Workouts, and Erg Mode

New to training with power? Sarah LaRoque (YouTube channel “Everything is Photogenic”) breaks down some of the basics of structured workouts on Zwift and other indoor training platforms. If your eyes glaze over when people start talking about FTP and ERG, her conversational style might help!

First, she explains Functional Threshold Power (FTP) and the tests that help you find your FTP. This is the number that Zwift bases your workouts around to make sure they are at your level and have the right training effects. It’s more commonly defined as the power you can sustain for about an hour, but you might not be able to hold it for that long, and that’s okay.

When you’re not using a smart trainer, you’ll shift gears and pedal faster or slower in order to match the target power in workouts. A controllable smart trainer gives you the option of using Erg Mode. This changes the resistance in order to get you to the target power using whatever gear or cadence you’re using. Turn off Erg Mode and you’ll be in Resistance Mode, which works like a non-smart trainer except you can manually change the resistance.

Watch the video:

LaRoque also explains the different training zones and how they are represented on Zwift. (These are close to, but not exactly the same as, Dr. Andrew Coggan’s power levels. Learn more about how they compare, and how Zwift divides the zones, with the help of Shane Miller’s video.)

  • Zone 1 (Gray): Active Recovery. Not for building fitness.
  • Zone 2 (Blue): Endurance. All-day aerobic zone, where you should be able to ride for a long time.
  • Zone 3 (Green): Tempo. Brisk, sustainable, but challenging over time.
  • Zone 3+ (Green, Yellow): “Sweet Spot.” A well-balanced training zone just below your FTP.
  • Zone 4 – (Yellow): Threshold. At or near your FTP, this zone is always going to be difficult for any sustained amount of time.
  • Zone 5 – (Pale Red): VO2 Max. The power you can hold for 3-5 minutes, maybe up to 8 minutes, at a very hard effort.
  • Zone 6, 7 – (Bright Red): Anaerobic and Neuromuscular. This is your 1-3 minute power and your sprint power.

Zones 1, 2, and 3 primarily use fat for fuel, while zones 4, 5, 6, and 7 primarily use glucose (sugar). Zone 3+ is balanced between them. LaRoque points out that knowing your training zones can help you fuel appropriately before and during your rides.

Now that you know what to expect and what those colorful graphs mean, it’s time to get to work! Happy training!

The Zwift Omnium

8

December 17, 2020, is a date burnt on my brain, scorched on my hippocampus. 9.37pm on that fateful Thursday to be exact. That is when I got the fateful message. Zwift was adding four new routes to Watopia. A fly in the ointment? This was more like a killer hornet in the chamois cream.

How could Zwift do this to me? And here I was, thinking we were friends. I was on the verge of cycling greatness (in my own mind at least) but this news meant I’d still probably languish in the ‘below-average’ category.

Finding the target

This will no doubt come as a complete bolt from the blue, but Covid messed up our cycling plans for 2020. We’d missed out on Gent-Wevelgem and L’Etape and, by the end of summer, I was feeling bored, fat and disillusioned with cycling in general. It says everything when the highlight of your ride is thinking of a witty Strava title. I had no goals. No pot of gold waiting at the end of the rainbow. The 365-Day Challenge was a non-starter and my annual 10,000km cycling target had been reached by the end of September. Three months of limbo loomed… until Zwift offered salvation.

The Famous Five

It was after doing all the France stages, including Ventoux – sorry, ‘Ven-top’, which took me right back to the GFNY Ventoux – that it dawned on me I could complete all the Zwift routes before the end of the year. My OCD (Obsessive Cycling Disorder) finally had a focus. 80 courses, 2,459.8km (including ‘lead-ins’) and 36,496m (not including ‘lead-ins’) of elevation gain.

Luckily, I already had around 50 of them under my belt. Most of the routes remaining were of the half-arsed, half-hour variety, easily accomplished in-between the school run and a supermarket sweep. I won’t even attempt to describe them all here as Zwift Insider goes into all the necessary depth and detail.

It’s a hard, socially awkward thing to say out loud, like admitting you have a favourite child, but Zwifting began to be more enjoyable than being outdoors. The temptation to do ‘real’ riding receded as the mornings got darker and the weather got colder and wetter. I no longer saw the point in pootling around south London for an hour – not when I could be ticking off the Greatest London Flat or the Lutscher CCW.

One-by-one, the courses were conquered, until by the beginning of December, there were just five pockets of resistance remaining. The Famous Five. Or should that be The Infamous Five? Quatch Quest. The Mega Pretzel. The Über Pretzel. Four Horsemen. PRL Full. Names to send a shiver down a Zwifter’s back.

War of the worlds

The problem with the remaining routes is they take so damn long to complete, whether it’s because of the distance, elevation, or both. One hour on a turbo is beautiful; two is distinctly unappealing; three is getting ugly; four is horribly disfigured; five is on fire and put out with a golf shoe. Let’s not even talk about six hours just yet.

The tedium sets in around the 1hr 15min mark (see, I was so bored that I actually took the time to think about when I got bored!). But this at least allowed plenty of time to ponder my top-five Watopia regions:

5. Jungle You can absolutely bomb it down half of the course but the return segment is really draggy. Always seem to get bogged down but plenty to look at.

4. Volcano Smash out the circuit or do the climb. Either way, it’s a really interesting course that rewards sprinters and grimpeurs.

3. Epic KOM Here’s a suggestion: Do the ‘Reverse’ route first. Unless you’re on a go-slow, you’re pretty much guaranteed a Zwift jersey. But this is a great test from either direction.

2. Alpe du Zwift Having done it IRL, I’m still struggling to remember the Gothic chateau halfway up but, apart from that, it’s reasonably accurate in terms of gradient and how knackered you feel doing it. Just a shame I couldn’t get off and sit on one of the hairpin walls like I did during the Marmotte.

1. Titans Grove Easily the most fun. Lumpy but not ridiculous, you get back what you put in. Plus I think it’s the most pleasing visually, with pterodactyls flying overhead and T-Rexs roaming around.

Come to think of it, I also had oceans of time to mull over my top-five guest worlds. In reverse order: Yorkshire, London, Richmond, Innsbruck and France. New York doesn’t make the list, not because the routes aren’t challenging but because I’ve never really enjoyed the futuristic setting or imaginary climbs.

Race against time

A month seems plenty of time to do just five courses. But that doesn’t factor in having a boisterous six-year-old, a new job and everyday chores that weren’t going to do themselves. Spending five hours on the turbo, followed by another hour defumigating a pungent living room/pain cave, wasn’t the most selfless use of my time. Thankfully, I have a very understanding soigneur.

First to fall was Quatch Quest on December 7. Just the 2 hours 43 minutes of moving time, most of which was used up tackling the Alpe du Zwift at the end.

Four days later, after quitting a couple of times previously, Four Horsemen went the same way. 3 hours 37 minutes to cover 90k is slow going on Zwift but, by this stage, it was all about completing, not competing.

December 15 – the Mega Pretzel. This was when I started Zwifting into uncharted waters. More than 100k and 3 hours and 40 minutes on the bike. It was the day when the enormity of the challenge – and the enormity of the boredom – set in.

The Über Pretzel was nibbled rather than devoured on December 17 – cue a shudder – my biggest struggle since the Chilterns Challenge. A mammoth 142km and 2,387m of elevation, which took a snail-like 5hrs 25mins to complete.

That left just one to go, the PRL Full, and a whole two weeks to do it. But that was before the text arrived that evening to throw not just a spanner, but an entire toolbox in the works.

Super Saturday

Seeing the single tear roll down my flushed cheeks, my wife stepped up to the plate again. Selflessly sacrificing her own hopes for a relaxing Saturday close to Christmas, she promised to take our daughter out for a couple of hours so I could cross off all the four new routes in one day.

A Strava follower later asked which was my favourite out of Beach Island Loop, Ocean Lava Cliffside Loop, Serpentine 8 and Two Bridges Loop. I couldn’t honestly say. I’d been so tunnel-visioned in just getting them done, I hadn’t paid much, if any, attention to my virtual surroundings. I vaguely recalled the Mayan Bridge being kind of cool, but that was pretty much it.

The only thing that now mattered was the PRL Full – and, crucially, when London would next be a guest world. My circumnavigation window was narrowing.

London calling

December 27 it was. I’d like to say the PRL Full was a glorious, fun-filled finale to my Zwift journey but that would be a blatant lie. It was a monotonous 11 ascents of Box Hill. 2496m of climbing over 173km. Something I just had to do, rather than had any desire to do.

By the fifth time up Box Hill, I needed a 15-minute break; by the seventh I required an hour’s R&R, which included a visit to the local off-licence. Like much of lockdown, if I was going to do this, I wasn’t going to do it sober.

Replenished by a few cans of Polish lager, plus a punchy IPA from a local brewery, the thighs and brain were suitably numbed to finish off the final 25k, with a much-needed glass of champers waiting for me at the finish. 6 hours and 10 minutes. I’d sweated through three bib shorts and four headbands, and the lounge smelled like a rubbish dump, but never has a glass of bubbly tasted so sweet.

Would I do it again? Most certainly not, I couldn’t even look at the turbo for several days afterwards. But, then again, there are still a lot of Zwift badges to be earned…

The other brother

Zwift is kind of like Crocs or margarine: innocuous enough, but capable of eliciting the most vitriolic reactions. It wouldn’t surprise me to discover a militant faction of luddites, actively sabotaging bluetooth connections and running interference on domestic wifi. Operating with the pseudo-religious fervour their 19th Century counterparts reserved for destroying textile machinery. How else do you explain the increasing number of drop-outs on Zwift recently?

Most objectors seem to focus on the fact it’s not ‘real’ riding. True, there was a time I refused to log indoor rides on Strava. I didn’t want ‘plastic’ miles to count towards my annual totals. Even now it feels disingenuous to boost your elevation tally by climbing virtual mountains. And yet training indoors can be every bit as exhausting as riding IRL. If anything, I tend to go harder when confronted with nothing but the cold hard facts of my power output.

Maybe what’s really eating at those left behind is the sense of abandonment. The competitive nature of Zwift is so compelling, the experience so utterly addictive, that once you see a friend taking trips to Watopia, you begin to wonder if they’re ever going to come back.

Zwift Tests “New AI” Pack Dynamics

Since sometime in December, astute Zwifters have noticed a “New AI” tag appearing on a small number of events. Then a few days ago, ZwiftHQ confirmed (via this FutureWorks forum post) they have been testing new pack dynamics in certain events indicated with this tag.

What’s different about the new pack dynamics, and how you can test it for yourself? Here’s what we know…

Why “New AI”?

The “new AI” tag is interesting in itself. Have you ever pondered that, without users doing the steering, Zwift has to use artificial intelligence to steer for us?

Even without the “new AI” tag, your avatar will veer around riders, and veer into their draft. Sometimes the AI isn’t very smart – it famously takes terrible lines in corners, for example! But overall, it generally puts riders in a sensible place.

Digging Into the New Pack Dynamics

Here are excerpts from Zwift’s forum posts on the new pack dynamics, explaining how they’re different from what we’re used to:

Experienced Zwifters may have noticed changes in the way your avatar moves around other avatars.

In Bike group events with new pack dynamics enabled – it affects the shape of the blob, and avatars don’t pass straight through each other like ghosts. They move around each other a little more realistically most of the time. You’ll see it happen still – it’s not perfect yet.

Game physics more accurate, including the positioning of the bikes on the road.

The movement and shape of the pack smoother and more human-like.

We didn’t change the math behind drafting, but the draft effect should be more realistic because avatar positionings are more accurate now.

That accurately describes the new pack dynamics, as I’ve observed them. I’ve noticed it causes groups of riders to be more spread out, and your avatar rides through other riders much less.

With riders more spread out, the draft effect seems to be reduced somewhat, which causes the packs to stretch out more, front to back.

Comparing the Old and New

Here are three short recordings made today, showing the new and old pack dynamics.

New pack dynamics, video 1:

New pack dynamics, video 2:

Standard pack dynamics:

How would you describe the differences between the first two clips and the last one? I would say riders seem more “jumpy” in the first two, as well as more spaced out. And there’s definitely less riding through other avatars in the first two clips.

Is It An Improvement?

Are the new pack dynamics better than the old? My take on it is: yes and no.

Not riding through other riders is a good thing, obviously. It makes the visuals feel more realistic. And having riders spaced out a bit more left to right feels better as well.

Although I haven’t been able to test/confirm this, I have a theory that the new dynamics may reduce the “churn” at the front of the blobs somewhat, because riders will veer around the front rider and into the wind earlier than they did previously. So instead of slingshotting off the front and continually bumping up the pack speed, the new pack dynamics may result in more realistic group speeds. Maybe.

Rider movements can be a bit erratic with the new pack dynamics, though. Riders will (seemingly) randomly veer left or right in the pack, like some sort of Cat 5 racer with a flat. It’s possible these are Zwifters running an outdated version of the game, but it’s also quite possible this is just the new pack dynamics needing a bit of fine-tuning.

While the “new AI” may not be perfect, I’m excited to see Zwift attempting to improve the pack dynamics. If this eventually makes our avatars’ movements more realistic and reduces the blob-accelerating “churn” at the front, that’s a major upgrade.

Experience It For Yourself

Want to test out the new pack dynamics for yourself? All of the Tour de Zwift make-up events are using the “New AI” tag. There are also some non-TdZ events using it – click here for that list.

An Active Approach to Cycling Injuries: Plyometrics

What is Plyometric Training?

Plyometric training utilizes quick, powerful movements to enable the muscles to produce the greatest force possible within the shortest period of time.  It is based upon theory and research proving that muscles have the ability to create greater tension when a rapid stretching phase is followed by a fast contraction, referred to as the “stretch-shortening cycle.” 

Training the body’s nervous system through focused dynamic exercise conditions it to react to the lengthening of the muscle by rapidly contracting with maximum force.  This is achieved through various jumping and bounding movements.

Why is Plyometric Training Important for Cyclists?

While the importance of plyometric training may be obvious for athletes engaging in jumping sports like basketball and volleyball, the benefits are less clear for cyclists whose feet never touch the ground.  It can’t be denied, however, that lower body strength is primary to cycling performance.  Research shows that the performance improvement potential of plyometric training for cyclists may be significant and difficult to ignore.

In a recent New Zealand study, well-trained cyclists were subjected to a plyometric training program consisting of single-leg jumps alternated with high-resistance cycling sprints. After 12 sessions the cyclists exhibited average gains of 8.1% in 1 km power, 6.8% in peak power, and 3.7% in lactate threshold power, all with 3% reduction in total oxygen cost.

The authors of the study attributed the gains to improvements in exercise efficiency and lactate threshold, the result of improvements in neuromuscular efficiency, or a faster stretch-shortening cycle.  If well-trained athletes realized such improvements, imagine the potential for amateur cyclists?

Plyometric Training Performance Tips

  • Don’t initiate a plyometric training program before first building a strength base and conditioning your muscles, tendons, and joints through at least 6 to 8 weeks of resistance training.
  • Perform a thorough warm up and muscle activation prior to initiation of plyometric exercise.
  • Do not perform plyometric exercise on fatigued muscles or following a demanding ride or run.
  • Limit plyometric training to 2 times a week and begin with 50-60 jumps per session (increasing to tolerance) to avoid injury.
  • Maximize jump height or distance with every repetition and minimize the amount of time spent contacting the ground between each.
  • Apply maximal effort to each repetition, and perform as quickly and powerfully as possible.
  • Learn, practice, and focus upon correct form and terminate your set or training session before it deteriorates.

How Dexter Yeats Keeps Pushing the Limits

When faced with challenges and adversity, most people can be placed into one of three categories: 

  1. Those who rise up to overcome, thereby finding greatness in themselves that they didn’t know existed;
  2. Those who deny themselves the chance to prove their greatness by an unwillingness to step outside their comfort zone;
  3. Those unique individuals who seek challenges, ever searching for the next way to test themselves and define their character.

For those individuals, the drive to succeed by pushing themselves ever higher is in their DNA, woven into the fiber of their being.  They awake each morning with a goal in mind, and the anxiety they feel to achieve it is self-imposed because failure would mean disappointing themselves above all else.  Dexter Yeats is one of those people.

An Impressive Endurance Athlete on the World Stage

Dexter Yeats is an elite endurance athlete, as this truncated list of her results shows:

  • 8x Qualifier for the KONA IRONMAN World Championships
  • 2018 Age-Group World Champion IRONMAN 70.3 South Africa (See results here)
  • 15x IRONMAN finisher (first in 1993)
  • Multi-time Western States Ultramarathon competitor (completing 78 miles in 24 hours)
  • 2020 Age-Group Champion IRONMAN Cozumel  (See results here)

When not cycling, running, and swimming on the roads and in the pools of her hometown of Coeur d’Alene, Idaho, Dexter can be found riding her KICKR bike and running the roads of Watopia under the acronym G. Grandma (Strava profile here), a tribute to her many grand and great grandchildren.  Yes…Dexter is 75 years old! 

Dexter’s Careers and Overcoming Their Biases

Dexter’s career as an elite endurance athlete began late, for life presented its own challenges for her as a mother.  Of course, Dexter didn’t choose to take the easy way out!  She worked as a Teamster trucker, driving big-rig 18 wheelers for 25 years in the San Francisco Bay area.

Dexter sought work as a trucker because, as she states, “My daughter wanted to go to school. I had to make a man’s wage to be able to afford her college,” she notes proudly. “It was equal pay for equal work and now she is a very successful surgeon.”

As a Female Master’s endurance athlete Dexter experiences discrimination of a different form.  “Seniors are not always given a fair shake with conditions,” she explains, “such as being given late start times, making it almost impossible to come in under the cut-off.”  She also admits to being humbled when attending events with young friends, “and they get asked about the race when I am the one racing.”

Atop Mr. Kiliminjaro

An Extreme Challenge    

The struggles Dexter faced as a female in the male-dominated trucking industry and as a Master’s triathlete prepared her well for another extreme challenge she chose to embrace.  On October 17, 2004 Dexter began a 6-day trek to the summit of Mt. Kilimanjaro. 

“I was 59 then and felt like I was getting old,” she states jokingly, “and the Sherpas didn’t believe someone my age could climb to the top. While on Mt. Kilimanjaro I learned to look at climbing in stages, and if you take one step at a time you will reach the summit,” she exclaims, “the grand reward!”

Dexter’s Personal Theory on the Stages of Challenges

  1. Present the challenge to yourself.
  2. Commit to the challenge.
  3. Gain the necessary training and skills.
  4. Accept that there will be failures and learn from them.
  5. Put your toe on the line prepared to give your best effort.

The Quest for Sub-60

Dexter is currently using that strategy in her quest to earn Zwift’s Extra Credit “Alpe du Zwift in Under an Hour” achievement badge

In 2019 Dexter competed as the defending Age Group 70.3 IRONMAN World Champion in France, where the bike course hit the slopes of  the legendary ‘Col de Vance.’  “On race day,” Dexter notes disappointedly, “the challenge [climb] was my downfall, and I did not make the time cut and wasn’t allowed to continue on to the run with the other ladies in my age group.” 

This has fueled the fire in Dexter to become a better climber. 

So far, Dexter has improved her Alpe time from 99:20 upon her first attempt, to her most recent climb of 67:53, placing her in the top 50 for 60+ female Zwifters (see Zwiftpower segment stats).  “I don’t think any of those days on Mt. Kilimanjaro was as hard as the hour pIus I spent climbing ADZ,” Dexter remarks, “I can only imagine how doing it under an hour will feel.” 

I am confident Dexter will get the chance, but not as confident as she is!

Dexter’s Tips For Being a Successful Master’s Athlete:

  1. I think being consistent is very important.
  2. Listen to your body and don’t get tangled up in numbers.
  3. Recovery is the key to better performance.  

Climbing is Life for Dexter Yeats

Dexter sums it up best when describing her motivation and the insatiable drive to push herself to the limit… and beyond.

“Life is a series of challenges. Climbing hills is also a series of challenges. There are many summits in life that we all attempt to reach. Once we reach one of them, we look for and set our sites on the next summit. Summits can be relationships, jobs, places we live, retirements, or even earning badges on Zwift!”

Well said, Dexter!  Ride On!
