All About Your Critical Power Chart on ZwiftPower

Cycling is a voyage of self-discovery. While it teaches us a lot about how we think it also teaches us so much about our physical selves. How much recovery do I need? How strong am I at different types of efforts (sprints, endurance rides, etc)? And how do my physical strengths rank against others?

Thanks to the universe of data amassed by ZwiftPower, Zwifters have a powerful, free tool at our fingertips to help us better understand our physical selves. But before we dig into that, let’s lay a foundation.

Rider Phenotypes

“Rider phenotypes” categorize cyclists based on their maximum average power over different time periods, also known as “critical power”. The time periods vary from book to book or coach to coach, but one popular model uses 5 seconds, 1 minute, 5 minutes, and FTP. A rider’s power numbers may be placed on a graph, creating something like this:

Bar chart titled Pursuiter comparing cycling performance levels (World Class to Novice 2) for 5 seconds, 1 minute, 5 minutes, and FTP, with highest value at 1 minute (14.89 W/kg, World Class).

chart from Training and Racing with a Power Meter, 3rd Edition

In Training and Racing with a Power Meter the authors define the following phenotypes:

  • All-Rounder: generally even across all four time periods.
  • Sprinter: downsloping plot with best power in the 5s range
  • Time Trialist, Climber, or Steady-State Rider: upward-sloping plot with best power in the FTP range
  • Pursuiter: an inverted V-shaped plot with the peak in the 1-minute range

What’s Your Phenotype?

Here’s the fun part: ZwiftPower displays critical power charts on the profiles of each ZwiftPower user, allowing us to see where our strengths and weaknesses lie. Just view your profile page (here’s mine) and look at the graphs directly below your profile pic. Here’s what mine looks like today:

Two charts show cycling power data: left chart displays 15 sec (11.16 w/kg), 1 min (6.50 w/kg), 5 min (4.46 w/kg), 20 min (3.86 w/kg); right chart shows 922W, 531W, 371W, and 319W for same durations.

Mouse over each bar for a little more detail, including a percentile ranking against the overall cycling population using Cycling Analytics’ numbers found here. (This percentile grade is split by gender.)

The bars on the left display your power numbers in w/kg, while the bars on the right display them in pure watts.

Your best three bars in terms of population percentile rank are color-coded – these are your strongest points. Orange is your best, dark blue second best, light blue third best. So in my profile, my best is 20-minute wattage, followed by 5-minute and 1-minute.

A Word about Data Quality

It’s worth noting that your phenotype charts will only be as good as the data fed into them. ZwiftPower uses your last 90 days of group ride data for its phenotype charts, so if (for instance) you haven’t put in a hard 20-minute effort in the last 90 days, your chart may show you as a weak Long Climber or Time Trialist even though you may be very strong. And keep in mind this is only for events set up on ZwiftPower, which means your free rides or personal workouts won’t be included.

If you are regularly participating in all-out Zwift races of varying lengths your charts should be quite accurate.

Using the Data: Racing

Two charts show cycling power data: left chart displays 15 sec (11.16 w/kg), 1 min (6.50 w/kg), 5 min (4.46 w/kg), 20 min (3.86 w/kg); right chart shows 922W, 531W, 371W, and 319W for same durations.

A quick glance at a Zwifter’s chart can tell us what sorts of race situations suit them best. In my chart above we can see that, first of all, pure wattage is my strength. Power to weight (w/kg) is not! So I’ll do better on flatter courses, where wattage determines speed more than w/kg. Since my 20-minute power is my biggest strength (69.98% rank), I’m looking for flat TTs, or road races where the pace stays high throughout and there is a lot of attrition as riders drop off.

Now look at my weakest bar: 5-minute w/kg of 4.46w/kg (49.22% rank). My chart says that if a race involves a substantial climb in the 5+ minute range, I will struggle to stay with the front riders. And guess what: that’s true!

Contrast my chart above with the current world top-ranked Zwift racer, Stefan Kirchmair:

Bar chart displaying cyclist power output: 16.87 w/kg at 15 sec, 10.35 w/kg at 1 min, 6.70 w/kg at 5 min, 5.79 w/kg at 20 min; and 1080 W at 15 sec, 653 W at 1 min, 429 W at 5 min, 371 W at 20 min.

You’ll notice his best numbers are all on the w/kg side, indicating he excels in races with substantial climbs. His 20-minute power of 5.79 w/kg places him in the 98.66% rank, indicating that very few riders can beat him on long climbs. This is the power profile of a rider who is nearly unbeatable when the road tilts upward!

Not all top racers are lightweight climbers, though. Holden Comeau is the 2019 Zwift USA National Champion, currently ranked 3rd in the world. Check out how different his profile is from Stefan’s:

Two bar charts compare power data at 15 sec, 1 min, 5 min, and 20 min intervals. Left shows 17.96, 9.84, 5.66, and 4.68 w/kg; right shows 1402, 768, 442, and 370 watts. Highest values are at 15 sec.

Holden doesn’t win races by attacking on long climbs – he sits in the pack and wins in the final minute with a super-strong ramp up punctuated by a blistering sprint. With 1-minute power of 768 watts (99.07%) and 15-second power that is ranked over 98% both in pure watts and w/kg, Holden is a rider you have to shake off well before the finish if you want to win!

Holden vs Stefan

If Holden and Stefan raced against each other they could use these critical power charts to come up with a plan and give themselves the best chance at a win. Let’s say they were racing Watopia’s Mountain 8, which begins with a climb up the reverse Epic KOM and radio tower (~18 minutes), then descends to a flat finish of approximately 9km.

  • Stefan would want to get away from Holden on the climb, putting as much time into him as possible while the road is steep. Then he would want some high-wattage teammates to tow him to the line, keeping him well ahead of Holden so it doesn’t come down to a head-to-head sprint.
  • Holden would want to limit his losses on the climb, perhaps using teammates to lend a bit of draft and pacing. Then he would want teammates on hand to help him reel Stefan back in on the descent and final flat portions of the race, forcing the race to end in a head-to-head sprint.

Using the Data: Training

Just as the phenotype chart tells you your strengths, it also tells you where you are weakest. Coach Shayne Gaffney says “race your strengths, train your weaknesses.” Even if you aren’t working with a coach, you can use these charts as a simple guide to spot your weakest points.

I know I need to work on my 5-minute power while dropping a bit of weight. What about you?

If you’re looking for a resource to help you train, check out the latest edition of Training and Racing with a Power Meter. The other book I’d highly recommend is “The Cyclist’s Training Bible” by Joe Friel. This is a very well-respected resource from one of the most trusted cycling coaches in the world.

Conclusion

There’s much more we could discuss with these rider phenotype numbers, but I hope this gets you started. Questions or comments? Post below!

Time Flies When It’s Flat and Hot – Tips for WTRL TTT #82 – Tempus Fugit

About this Series

Since March I have become obsessed with the weekly Team Time Trial… so I asked Eric if I could share my obsession with you all, in weekly doses.

Each week on a Friday 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! Don’t forget to tune in to the live TV show on Zwift Community Live’s YouTube Channel at 6:15 (UK time). 

Review of TTT #81 UCI Richmond

Over to RIchmond VA for the TTT last week. I took a break from my time targets – and well done to Joy Murphy of the ZSUN Saturn Frappe team – for calling me on it. ZSUN are one of those great forces in Zwift racing – and they have almost 30 teams! It’s great to know you guys have your eyes on the weekly recce, and even better that you like the target times!

Going into the TTT this week I felt very good about the R&K Hyenas. As a feeder and training team for R&K we are constantly getting new riders… then waving them goodbye. Over recent weeks so much has changed that I am the only rider left from the summer! That said, the mix of riders we have going to Richmond seemed the perfect squad for 8 ½ km flat and 8 ½ km with those three bumps. Two riders with a lot of oomph to go with their mass, four lighter climbers, and two all-rounders. We had a plan that would get us through lap one together, and a plan for the endgame.

Mike Tyson, famously, said “Everyone has a plan until they get punched in the face”. My plan got punched in the face pretty early on when two of our climbers got dropped – and in the aftermath the DS (that’s me) made the totally wrong call about whether to go back for them, leaving himself in the wind for a couple of minutes. These are the things races are made of – and while the team performed amazingly, their DS let them down (#sadface). Ah well… next week is another race!

Results are finalized now – so here are the PL times from UCI Richmond:

Category#47 PL#81 PL
Vienna1:14:45 (10 teams)49:51
Espresso48:06 (7 teams) 43:58
Frappe49:1746:00
Latte53:1750:45
Mocha1:08:1057:31

Massive gains between #47 and #81… demonstrating the level of professionalism and competition between March and November. Well done and “Ride On” to every team that rode out yesterday!

Thursday 12th November – Two laps of Tempus Fugit

We were last on Tempus Fugit in April this year (WTRL #52), and before that in January. WTRL #52 was my second TTT, and I went out with the CICC lads, a fine bunch of (mostly) expats living in France. Why they adopted this lost lamb from Colorado I don’t know. But they did, for which I will be forever grateful! 

Tempus Fugit has to be the flattest route in Zwift, making it the least technical TTT possible. That is perfect for any team wanting to show off their perfect paceline skills to reach max-aero without interruption from course-related complications. The highest mountain you will climb here is… 7m tall. A welcome change from Richmond perhaps. 

The Fuego Flats desert course that makes up Tempus Fugit is one of the most popular spots on Zwift, so I’m pretty sure every one of you has been there. The course for Thursday is two laps – so from the Fuego Flats pens it’s a 2.4km lead-in, up and around the cool futuristic building in Saddle Springs (the LAX control tower), back and through the start/finish arch, around the loop and back through the start/finish to complete the first of two laps. This is a fairly long TTT at 37.1km, but it is fast… very fast. A top-flight Espresso team will average 50kph and be done in 45 minutes… while the slowest Mocha team will be in and out in just over an hour.  

What to ride?

Don’t ride this

This course is flat… aero-rules-all kind of flat. At the top end, you are looking at Venge S-Works + Zipp 858/Super9 over Tron, with the Aeroad following close behind. Whatever you do, don’t ride the one in the picture above… however sexy it looks!

Here are the recommendations at various levels:

  • Level 6 Zwift Aero frame and DT Swiss ARC 62 wheels
  • Level 13 Canyon Aeroad 2021 and Zipp 808s
  • Level 33 S-Works Venge with ENVE SES 8.9
  • Level 35 S-Works Venge with Zipp 808/Super9
  • Level 45 get those 858/Super9 wheels and pair them with the S-Works Venge

I know I say it every week but it is doubly important this week. Get the Tron! Someone on one of the Zwift Facebook groups asked “what is the one thing you wish you’d known at level 1”… the answer is I wish I’d known how important Tron was! 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. On this course Venge S-Works beats Tron… but Tron remains the perfect “set it and forget it” bike.

Route Recon Rides

A few places to go for information – a race-focused recce from Zwift can be found here. Of course, it is focused on profiling the course from an individual racer’s perspective, but worth reading anyway. 

There are so many ways to recce this route – the simplest being to hop on and select Tempus Fugit. If you want an organized ride or race follow this link to Zwifthype. There are a lot of individual TTs on the roster since this is one of Zwift’s iTT routes – and that can be an interesting way to test yourself. 

Paceline skills are going to be a huge differentiator this week – so if your team wants to do some paceline practice remember you can always set up a private group ride (Meetup) in Companion!

Race Breakdown 

There really isn’t a breakdown of the route that makes sense… other than scenery there is nothing that gets in the way of good team formation. Take a look at the Veloviewer profile (I have purposefully stretched the elevation so you can see the “hills”) and you can see the flatness… one rise in the middle of the map, and another even smaller one in Saddle Springs… 

Target times

Tempus Fugit has been ridden in two TTTs this year – in January and in April. January wasn’t competitive, perhaps because everyone was still hungover. #52, in April, was much faster – but I think the influx of teams and the honing of skill will drive up the speeds of the teams significantly in #82.

Category#37 PL#52 PL
Vienna1:10:09 (6 teams)55:20
Espresso51:49 (9 teams)47:30 
Frappe51:2249:19
Latte55:1353:07
Mocha1:02:36 (7 teams) 1:00:28

So what do I think will happen this week? Well… I think times will be faster across the board. I have assumed the same splits (10k, 20km, 30km) as the last time. Here we go:

Category10km split20km split30km splitFinish
Vienna14:4029:2043:3052:25

Latte14:2028:4543:2052:50
Mocha16:0031:5048:0058:24

I took a little break to think about my life choices after being so far adrift 2 weeks ago. Let’s see how Tempus Fugit treats me!

As for the Hyenas, I don’t know who the team on the ground will be – but right now I’m going to set a target time of sub 54 minutes.

Wrap up

This race is all about team time trialing teamwork. There isn’t anything in the 34km that will get in the way of your team’s aero-excellence. Frankly, while I usually say get out there and recce the route, here I say get out there with your fellow riders… and practice teamwork!

Z Pro Tri Race Series Returns: New Format, Community Racing

0

Zwift’s first Z Pro Tri series earlier this year successfully showcased Zwift bike racing to the pro triathlete crowd. Now Zwift has announced the return of the series, with a revamped format and the opportunity for non-pro community riders to participate! Here are the details…

New Format

The brand new 3-part race format will test the all-round abilities of racers. Each week will include a Points Race, Scratch Race and an Individual Hill Climb TT. Events are scheduled together, so you can go from the points race directly to the scratch race and into the TT (each race is approximately 30 minutes long.)

Community riders can race all three back to back “for the full Z Pro Tri experience”, or just jump into one race and give it a try. Each week’s racing will mirror the courses which the pros race.

Community Series

Dates, times, and route details for the community races can be found at zwift.com/zprotri.

Events began November 6, and run through November 26.

Pro Series

The pros will begin racing on November 11.

This race series will be live streamed on Zwift’s Youtube and Facebook channels, with Matt Lieto and Sarah True providing commentary. Here are links to the upcoming race broadcasts:

Race 1 on YouTube (November 11, 11am PT)
Race 2 on YouTube (November 18, 11am PT)
Race 3 on YouTube (November 25, 11am PT)

The start list for each race contains 20 of the biggest stars in the sport, in both short and long distance racing. Confirmed athletes include Teresa Adam, Holly Lawrence, Laura Philipp, Emma Pallant and Annabel Luxford. On the men’s side, Alistair Brownlee, Jonny Brownlee, Sebastian Kienle, Joe Skipper and Antony Costes.

Zwift Racing League 2020/21 Round 1 Week 5 Guide: Everything Bagel

14

The fifth week of Zwift Racing League is upon us, and it’s going to be a punchy climber’s dream racing New York’s Everything Bagel. Let’s dig into the course, including some tips for bike choice and key selection areas.

Looking At the Route: NYC Everything Bagel

Here’s a route preview from Rick over at No Breakaways:

Route Breakdown

This route is basically never flat, but it’s not as pitchy as the profile below might lead you to believe. Still, the key selections of the race will happen on the first climb, which begins just 2km into the race!

The NYC KOM Reverse climb is an interesting one, because it’s really two climbs. First you’ve got the lead-in of ~800m, then the actual timed segment of 1.1km. Make no mistake – the effort will began at the bottom of the lead in, and it will be an all-out slugfest because riders know that all the intermediate bonus points will go to the group that makes the front selection.

After a quick descent (can the chasers recapture the front group?) the next intermediate is a sprint at ~13km. This has a quick kicker climb leading into it, so keep your eyes open and hammer that climb if you want to take sprint points.

Our next climb comes at 18.5km as we transition from the ground-level tarmac to the glass roads. This section is about 1km long, and is the longest climb on this route apart from the two KOMs.

Then we arrive at the forward KOM, which like the reverse has a lead-in (at 24.2km) before the official timed segment. Expect another all-out effort here as riders push to thin the pack and increase their chances for intermediate points at the top of the climb and the upcoming sprint.

Our final intermediate is the forward sprint at the bottom of the KOM descent, 28.1km in. This is a longer sprint section, so timing is crucial. Then it’s 6km of rolling roads to the finish, where timing is also vital! Many riders go too early here – a course recce is recommended.

Bike Frame/Wheel Choices

We tested various setups over this full course, and looked at segment times for the crucial KOMs. Here are the results:

Frame + WheelsetLapKOM RevKOM
Specialized Tarmac Pro + Lightweight Meilenstein56:413:34.694:34.00
Zwift Concept ZI (Tron)55:543:34.904:34.10
Canyon Aeroad 2021 + DT Swiss ARC 6256:103:34.914:34.23
Canyon Aeroad 2021 + ENVE 7.856:013:35.094:34.30
Specialized Venge S-Works + Zipp 858/Super955:553:36.004:35.44

Keep in mind the reverse KOM has a lead-in climb as explained above, so the time gaps above will actually be 30-40% larger over this first crucial climb. Is it worth going with the “pure climber” Tarmac Pro + Lightweights in order to gain an advantage of ~0.3 seconds, if you’re going to lose so much in terms of overall lap time due to the wheels not being very aero?

We don’t think so. Our pick for this course is the Tron bike, which performs next-best on the climbs and is fastest overall on the lap.

If you don’t have the Tron bike, look at the Aeroad 2021 + DT Swiss wheels for a rig that climbs almost as fast, but is available at only level 10.

And definitely do not go with a disc wheelset. That’s going to hurt you on the crucial climbs.

Strategic Options

There are 4 intermediates on Everything Bagel, each awarding extra points for those first over the line (5, 4, 3, 2, and 1 points). They come in this order:

  • KOM Reverse
  • Sprint Reverse
  • KOM Forward
  • Sprint Forward

There’s no escaping the fact that this is going to be a tough race for the sprinters. Because if you’re not able to get over the top with the front group, you’ve lost your chance at intermediate points.

There’s a slight chance that the front group will be small enough (and the chase group large and strong enough) that chasers could rejoin the front group on the descent after the first KOM. So if you find yourself just behind the front pack, don’t despair. Your group will have to work together to make something happen and pull back the front group, but especially if you’re still in or close to the top 30, it would be worth pushing to rejoin that group.

Some teams may attempt to “protect” their sprinters and try to get them over the first climb. We think this is a fool’s errand. The group will be too fast in the initial kilometers for you to attack and get a significant gap on the climbers, and that first climb is too long for you to preserve a gap of only a few seconds. (The only scenario where this may work is if your sprinter is just a few seconds back over the KOM, and another teammate gives them a wheel to pull them back into contention.)

This week’s race, more than any other on the ZRL season schedule, will see many riders dropped within the first 5 minutes, with no hope of getting anything except the single point for finishing the route. Enjoy your gruppetto time – it’s a rare experience on Zwift!

Lastly, powerups: there will be five opportunities for a powerup on this route. Make sure you know how each powerup works, and use them wisely! Hint: the anvil may prove useful on the descents following the KOMs.

How the Race Was Lost: ZRL Week 4 TTT on the Magnificent 8

23

This was the fourth week of Zwift’s groundbreaking Zwift Racing League, and the second team time trial of the series. Since this was our first TTT after being seeded into our division (Men’s EMEA East 2 Division 1B), we weren’t sure how we’d stack up against the competition. But we knew we were up against some very strong teams, and it would take every bit of power, technique, and strategy to come up with a good result on Watopia’s Magnificent 8.

The Warmup

My race prep followed the usual pattern – chewing some caffeine gum and applying PR lotion to the legs. Drank some beet juice as well, because I’m a glutton for punishment (that stuff tastes terrible). Then it was time to suit up and warm up.

My team (DIRTy Beasts Hellhounds) has members based in the USA, UK, South Africa, UAE, and Australia, so we’ve struggled to get together and practice apart from our pre-race warmups. On top of that, none of us have raced together prior to ZRL! But we’ve gotten along swimmingly and come to agreement on each week’s strategies via Discord text chat throughout the week.

Snowy Pruett, our team manager, had organized a Meetup on Tempus Fugit which began 35 minutes before we had to be in the start pens. Our plan was to chat on Zoom during this Meetup, to practice our rotations, and talk strategy. This worked out well, although our rotations were anything but smooth during these practice rounds. More practice is clearly needed, but we had no more time – to the pens!

The Start

We’d decided to try the start “launch” technique explained in a recent No Breakaways TTT Master Class video. Basically, you stay on the pairing screen (which prevents you from moving), rev up the watts as the final seconds count down, then hit Escape to close the pairing screen when the countdown hits “1”. This lets you jump up to full speed very quickly, as opposed to starting your pedaling when the clock hits zero.

It worked well, and we jumped off the Watopia pier and into formation quickly. I was to be behind Paul Robertson, and each of us had agreed to don a unique piece of headware so our avatars would be distinctive. Paul was in the a blue hat, then other team members had black, green, white, orange, and me with red.

Justin Wild took the first pull, then Paul, then I was up. I was feeling good so early in the race, so I let everyone know I’d take a 1-minute pull. My speed at the front, though, seemed stuck at 45kph, and we were shooting for 46-47 on the flats. I pushed harder, trying to hold 425W+ for the duration.

We quickly made our way through the Volcano and over the land bridge, then we encountered our first challenge: the twisty dirt climb to the Italian Villas. First the dirt slows you down, then the incline slows you even more! By the time I reached the top I was wondering if I’d overcooked it already. But I pushed to stay on Paul’s wheel and breathed deep, trying to recover a bit before the big climb.

Hilly KOM Reverse

Our plan on the climb was to push hard on the steep initial section, regroup on the flat, then ride as a blog to the top, letting stronger climbers pull at the front. Our strong climber Scott led us outup the climb as we caught and passed our first rider, then it was a hard effort up around the statues and back into blob formation. We kept pushing, then I went hard on the final straightaway, trying to pull keep our speed up, knowing recovery waited just around the bend:

We supertucked down the descent, made the neck-breaking turn onto Ocean Boulevard, then got back into formation. Fuego Flats was just up the road.

Fuego Flats

I made my worst rotation mistake of the race on the false flat leading into the desert. As I eased off to sink to the back of the group, Justin and Paul got stuck on my wheel, and no matter how much I eased they didn’t come around! A 20-30m gap opened ahead of me, forcing Justin and Paul to put in a harder dig once they got around my wheel.

This is definitely an area where I need more practice – timing my power so I quickly slide back after taking my pull, without taking any teammates with me or dropping off the back to far.

My poor technique aside, we arrived in Fuego Flats intact, with all 6 riders chugging along. We had already discussed the fact that the flat final section of this route would require efficient rotations and high wattage in front in order to maintain top speed, so we all settled in to make that happen. The desert kilometers went by quickly, and soon enough we were in the Ocean Boulevard tube, ready for the final push.

Here’s what a rotation through the desert looked like in the Zwift Insider Pain Lab:

The Finish

Our beautiful single-file formation had devolved into a blob starting on the Col du Saddle Springs ramp, and our speed seemed sluggish now as we made our way through the underwater tunnels. I voiced some encouragement over Zoom: “Just a few more minutes guys! We’ve got to push harder!” Justin Wild, the voice of experience on our team, said “If you’ve got power, move to the front.” Oh yeah – that makes sense!

I put in a dig as we neared the ramp out of the tunnel, and Scott let us know he’d be pushing hard up the ramp then dropping off, since we only needed 4 riders across the line. With just 1km to go, it was time to go all in. I gritted my teeth and pushed with all I had. “Push push push” Justin was saying from his pain cave in early-morning Australia as my wife cheered and teammate Alex from the UAE crossed the line first. I came in just behind him, totally spent!

Our final time was 40:30.837 according to WTRL – good enough for 5th place in our division.

This was my first time including Zoom audio in the recording, but I realized afterward that my own voice didn’t get recorded. Still, you may find our chatter interesting…

Takeaways

I set a few power PBs in the 36-38 minute range during this effort, so I’m happy with that. 5th place in our division (which, along with the EMEA East 1 Division 1B, is the toughest division in our timezone) is a solid result for the Hellhounds, moving us into 10th place out of 22 teams. And while it was nice to have a little extra to pull the team along in some of the final meters, I was toast by the time we hit the line – so I think I paced myself well.

Justin Wild is our strongest TT rider, and he’d been forced to drop out early in our first TTT event. It was very good to have him along for this effort – his watts helped enormously. It’s amazing what a difference a strong (or weak!) team member can make in a TTT.

As a team, we agree there’s still plenty of room for improvement in our TTT efforts. Keeping our rotation tighter is a big thing, and knowing just how hard to pull is another. We’re shooting for particular speed targets on flat sections, and will continue to hone our “sink and sprint” rotation method.

Zwiftcast Episode 91: Pace Partner Insights from HQ, Ray Maker on indoor cycling, and the gigantic success of WTRL

1

As the world waits – and much of Europe closes its doors – Simon, Shane, and Nathan try to be upbeat in trying times and consider the Two Big Hits in Zwift right now.

Pace Partners, or pacer bots, are a big success with Zwifters. Senior games guy Wes Salmon from ZHQ talks to Simon about scope for development and some ideas being tossed around to make Coco, Dan, and their pals even more bestie friends for Zwifters. The podcasters chuck in a few of their thoughts.

Ray Maker, or DC Rainmaker, is one of the most respected voices in sports tech. Simon pulls out two big indoor cycling talking points from Ray’s annual keynote address to the industry. The Zwftcasters have their say too.

And whilst the success of the WTRL TTT series may have been predictable, it’s made it no less overwhelming for the organisers. Simon talks to part of the leadership team, Martin Carew, about the headaches as well as the benefits of the TTT event that’s taking Zwift racing by storm.

There’s just time for a bit of Zwift-related banter and as ever, the Zwiftcasters take up the challenge. We hope you enjoy listening!

How Does Zwift Calculate Rider Speed?

Your riding speed in Zwift’s virtual world is determined by several factors:

  1. Watts: this is the main factor determining your speed. The more power you’re putting into the pedals, the faster you will go.
  2. World: road gradient, draft effects, road surfaces, and air density values in Zwift’s virtual worlds all affect the speed of your avatar.
  3. Weight: lighter riders will go faster on flats and climbs than heavier riders if both are putting out the same wattage. Heavier riders will descend faster. Just like outdoors! Read “How Rider Weight Affects Speed” for specifics.
  4. Height: taller riders are less aerodynamic than short riders, so the shorter rider will go faster if two riders are holding the same wattage and everything else is equal (weight, frame/wheels, etc). Read “How Rider Height Affects Speed” for specifics.
  5. Virtual Bike Choice: the frame and wheelset you choose affects your speed, as each frame and wheelset has a weight and aero (CdA) value assigned to it. See our frame and wheel charts for a detailed breakdown of the performance of each frame and wheelset on Zwift.

So How Do I Get Faster?

You can’t exactly alter Zwift’s physics or your height, but here’s the fun part: you have control over the other factors listed above!

Are you overweight? You’ve come to the right place. Cycling is an incredibly effective low-impact exercise that lets you burn calories without beating up your body. Couple daily rides with a smart diet and you can shed weight safely and quickly while gaining fitness. (Ride Your Way Lean is a good read covering the fundamentals of weight loss for cyclists.)

Want the fastest virtual bike setup possible? We’ve got all the info you need, and then some.

The biggest speed factor, of course, is power. What kind of wattage can you put out, and for how long? Every body is unique, and we’re not going to dig into training plans and philosophies here. What we will do, though, is recommend the “Build Me Up” training plan in Zwift for anyone looking to gain fitness via a proven training program designed by an experienced coach.

And we’ll recommend these two books – the very best resources available for cyclists looking to train smart with power:

Notes on Speed Mismatches

Zwift speed doesn’t match your Garmin speed? Since Zwift uses a variety of factors to mirror real-world physics, pairing your bike computer to your power meter or smart trainer will return a very different distance number than Zwift’s – and that’s as it should be.

Zwift speed doesn’t match your outdoor speed? Zwift simulates outdoor cycling quite well, but no system can factor in every single outdoor riding variable (think potholes, rider posture, and group dynamics for starters). Because of this, some riders have observed that their speed on Zwift doesn’t match their outdoor speed. But there are plenty of sensible explanations for this!

“Keep Everyone Together” feeling slow? The physics of group workouts on Zwift are modified in order to keep all riders together. For most riders, this results in a Zwift ride that feels slower than normal. Similarly, the “Keep Everyone Together” option in Meetups uses some black magic to keep your group together, often resulting in some riders moving faster than normal, while others move slower.

Garmin Never Stop Cycling Tour Announced

5

A new multi-day event series starts next week on Zwift! The Garmin Never Stop Cycling Tour is a “celebration of all cyclists, no matter your discipline.”

Four stages will be held from November 9-20, and you’ll have three days to complete each one. They represent four different types of cycling experiences – road cycling, time trialing, gravel riding, and mountain biking. Each route is a “signature course” for its category, with terrain that different types of riders will love! These Zwift events will be led by expert-level ride leaders.

Open and Women’s Groups

The Garmin Never Stop Cycling events are listed as group rides, but they do not use the ride fence and you will get results at the end. Some people might choose to race them, while others will cruise around for a social ride.

There’s an open category (A), where both men and women are welcome to participate, and a category for women only (B). Both ride the same routes for the same distance, and both are listed at “1-5 w/kg.” This usually means that riders are free to go at their own pace. When there is a ride leader, that person may announce a specific pace at the start, or she or he might just ride with the general flow of the group.

Ride Schedule

Nov 9-11 – Stage 1: Watopia’s Figure 8 – A Haven for Road Cyclists

  • Laps: 1
  • Length: 29.8 km (18.5 miles) Elevation: 234 m (768‘)
  • Description: “One of the most famous routes for road cyclists: the Figure 8. This ride covers the entire route, in both directions. This is perfect for an hour-long cruise with some short climbs and a nice mix of flats and rollers.”
  • Equipment: You’ll want a road bike and wheelset for this one, because the road is all tarmac. This route features a mix of flat roads and hills, so aerodynamics will be more important than weight.

Nov 12-14 – Stage 2: France’s Douce France – A Dream for Time Trialists

  • Laps: 1
  • Length: 24.1 km (15.0 miles) Elevation: 108 m (354‘)
  • Description: “This route was created for the first-ever Virtual Tour de France and is perfect for fast TT efforts through the upper portion of Zwift’s France map.”
  • Equipment: Be careful if you choose a TT bike for this one, because time trial bikes can’t draft in Zwift! Currently the event settings show drafting enabled, and they do allow you to ride the bike of your choice, whether it’s a time trial or road bike. This may change before the events actually happen.

Nov 15-17 – Stage 3: Watopia’s Road to Ruins – A Gravel Rider’s Wonderland

  • Laps: 1
  • Length: 29.6 km (18.4 miles) Elevation: 268 m (879‘)
  • Description: “Road to Ruins is where you’ll find a solid mix of both tarmac and gravel. The course is flat and all about maximizing your speed output. You won’t get bored, though. We’ve added a bit of elevation to keep things spicy. Clip in and have fun as you explore this course!”
  • Equipment: A gravel bike will ensure you don’t slow down too much on the gravel and dirt, while still keeping pace on the tarmac. Here’s our guide to how the different gravel bikes perform in-game.

Nov 18-20 – Stage 4: Watopia’s Jungle Circuit – A Shredder’s Paradise

  • Laps: 2
  • Length: 7.9 km (4.9 miles) Elevation: 79 m (259‘) Lead-In: 5.7 km (3.5 miles)
  • Description: “This all-dirt route is widely used for MTB riders who have a serious need for speed. Feeling competitive? Awesome. Swap your bike to get a faster record.”
  • Equipment: Mountain bikes go fastest on dirt roads, so if you want to ride one, take a look at our Zwift MTB performance guide.

Jersey Unlock

When you complete any stage, you’ll unlock a new Garmin kit to wear in-game.
