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 week we started pushing the endurance Boone was building, working to keep the watts higher over the duration of the ride. This fourth week was similar to week three, with some cadence work mixed in.
The Plan
As a reminder, here’s the basic plan we’ve 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 #13: More Power PRs with Cara
Our goal today was to ride with Cara as long as possible, then spin the legs out for a bit to cool down. Boone hung with Cara for 30 minutes, beating his old record by 5 minutes.
He told me, “My legs felt great at 27 minutes. And dead at 29.” He spun for another 15 minutes on Fuego Flats, but felt pretty dead – possibly because he’d been working outside all day, hiking up and down the side of a hill, stoking a burn pile with timber and breathing in smoke. He had also raced in Crit City the day before, so was probably feeling that effort.
Despite blowing up in spectacular fashion, he set some new bests between 25-30 minutes on his critical power curve with this ride.

Ride #14: Spinups with Dan
Today we decided to go for a more mellow effort with Dan Diesel – to purposely ride with Dan in order to keep the effort lower, while working on cadence with some high-RPM spinups.
Cadence work can be a real help for beginning cyclists like Boone, because it teaches your muscles and brain to fire efficiently. Think about it: cyclists are asking a diverse bunch of muscles to lengthen and shorten 90 times per minute in a precise pattern – that’s no small ask!
I told Boone not to shift to a harder gear, but just increase his cadence and try to hold it for 30 seconds or more without bouncing in the seat. On his first set he was able to barely touch 110RPM, but on subsequent sets he was closer to 120 as his brain and body got in sync with each other.
He did several of these spinups – this I think was his second attempt:
Ride #15: Chasing Cara, Earning Drops
Today we wanted to try another “How Long Can You Hang” outing with Cara, but after a short warmup. We wanted to see if a better warmup would let Boone hang longer with Cara, so he spun with Dan Diesel for the first 15 minutes, doing some cadence spinups but keeping the overall wattage pretty low. Then we exited the game so we could join Cara’s group.
Boone managed to hang with Cara for over 30 minutes this time, but that wasn’t a huge improvement from his previous Cara outing. What was impressive was how he was able to keep his power up after falling off the Cara group’s pace. A product of the warmup? Perhaps
He was hammering toward the end of the ride, and I couldn’t figure out what he was working toward until he told me, “I’ve got to get to 200,000 Drops!” And so he did. His first 25-mile ride, and his longest in terms of time as well, around 70 minutes.
This ride also set new power PRs throughout the 24-54 minute range, which is a big range for a new PR!
Ride #16: DNS
Boone had consistently kept our M-W-F-Sunday schedule since we began this challenge, but today was the first ride he skipped. He wanted a change of pace, and asked what I thought of him using the treadmill instead. Would a jog help boost his cycling fitness?
I shared my experience with him. “At your fitness level, doing more cardio/endurance work will help everywhere. When you get MORE fit, running won’t really help your riding much.”
So he did an hour on the treadmill – 5 minute warmup followed by 50 minutes of steady jogging and a cooldown. 4.3 miles total.
Week #4 Takeaways
Boone really felt like the cadence work helped him pedal more fluidly, so he was pleased with those results. And it was nice to have the power curve data Zwift supplies, so we could see how he’s been able to increase his wattage this week, even though he felt like he was “failing” near the end of some of his rides.
When it comes to building fitness, many people (myself included) find it motivational to track progress with specific data. Today’s tools make this easy for cyclists! Even if you don’t feel or look stronger from week to week, you can dig into the data and see your progress. There’s a lot of value in that.
One thing Boone has mentioned more than once is that it would be nice if Zwift had a Pace Partner in between Dan and Cara’s paces. At Boone’s current level, Dan is simply too slow if Boone wants to push himself – and Cara is so fast that Boone can only hang for half his ride.
I think more Pace Partners will arrive eventually, but this was a good reminder that Zwift needs a more diverse range of paces in order to meet everyone’s needs.
Support Boone

Thanks to everyone who followed Boone on Zwift and Strava and gave him lots of Ride Ons and Kudos. He’s loving it! If you haven’t done so yet, follow him on Zwift (name “Boone Bridges”) and Strava.

Problem with high cadence for me is the noise. It’s all nice and quiet until 80 rpm, but then above that I get really conscious about it.
I always ride with heapdhones…so noise is not an issue..even if my trainer is super silent…the fans blowing air are always noisier.
Go Boone! I’m slightly envious of him starting out, a bit like watching some get into GoT for the first time. I’m enjoying this series of posts. I didn’t have Zwift to boost me in winter months when I started out riding road bikes so it made spring riding the first few years pretty tough. I hope this is what gets him into an athletic mindset for life; huge gains beyond fitness to be made.
Great work Boone! Big fan of this series :). I am not familiar with this power curve graph, is there a way to see them for past rides? Or can you only see it in the post-ride overview?
Use intervals.icu. connect with Strava/Zwift and you’ll get all your power curves.
It’s only in the post-ride overview, unless you use a third-party service like Nikki references below (including Strava premium). ZwiftPower will give you a power curve as well…
Thanks Eric & Boone, Loving this series. (& love this website)
as a mid to upper level Cat D rider myself I am experiencing a similar issue with the jump from Dan Diesel to Cara Cadence. Certainly an additional Pace Partner focused around 2.0-2.4 would mean I could ride in my sweet spot rather than slightly above threshold with Cara or upper zone 2 with Dan. However, I view a ride with Cara as the same as riding with someone fitter than you (which in my opinion is one of the best ways to increase your own fitness).
Boone may be struggling with a perceived slow in progress from the initial fitness gains as he managed to go from being dropped by Dan to finding Dan too easy in the space of 2-3 weeks. But if every time Boone rides with Cara he can stay on the group for an additional 1 min then this can be seen as an achievement & fitness gain, rather than that he is “failing” in his goal. (and before long an hour with Cara will be more than achievable and he will have his sights set on Bowie!)
I’ve ridden on the MTB with Dan to make it a bit more work, but not as much as Cara.
I personally I’m hoping that Zwift will Have peace partners that will actually do the variance in ranges they posted As far as power is concerned. It is really enjoyable to ride with the paste partners when you’re recovering or just wanting to have someone to ride along with
Totally agree they need a Pace Partner between Dan and Cara. I’m in the same boat as Boone.
Agree on the pace partner issue! I’m a mid D with 20 minute at 2.4w/kg, 74 years old. DD is too slow and CC is too much for me currently! Maybe the fluctuating power within the range would solve the issue!
I’ve always found Zwift’s critical power curve to be a bit … weird. No vertical scale, for starters. And the curves displayed are not right at all. That’s not how a CP curve is supposed to look when you set a CP best (orange curve for this ride is below gray all-time curve for all time intervals).
Yeah, their CP curve is whacked for sure! But the data at least seems accurate, if you mouse over it to look at the numbers…
“muscles to lengthen and shorten 90 times per second” That would be 5400 rpm, leave that for week 7.
LOL! Fixed…
Would love to give Boon a race in one of TFC TTT mocha teams we cover US and Europe timeslots. D cat riders are so popular and most people move through and off (pardon the pun) int oC cat after a handful of races.
Agree on the pace partner between Dan and Cara. I find that I’m soft pedaling to stay with Dan but immediately get spit out the back when I switch to Cara unless I’m going pretty hard. I’d prefer to use the pace partners as a zone 2 ride rather than going hard. Something in between (around 2-2.5) would be perfect.
Isn’t it Coco Cadence for cycling and Cara Cadence for running? Or did he go for a run after riding w/Diesel Dan?
ZwiftHQ told me they were changing her name from Coco to Cara. Then they changed it in game to just C. Then released the running bot named Cara. So… I’m calling her Cara.
Hmmm…so there is two Cara Cadences? Zwift can’t even give a pacer bot a name without completely messing it up. No wonder they can deliver a new UI, fix the fence, etc….
Try riding the Mt Bike with Dan Diesel, makes it a little harder to keep up with him
good idea! or even a TT bike.
