Flamme Rouge Racing (FRR) has built a reputation for incredible and unique Zwift race events over the past three years, but this Saturday they’re doing something totally different: a 24-hour Charity Club Challenge!
The basic idea is simple: join one or more of the FRR events in order to climb France’s epic Ventoux climb to raise funds for good causes. Read below for details!

FRR is asking riders to donate at least a minimum amount through the FRR JustGiving page:
FRR asks that you share your VenTop effort with friends and family so they have the opportunity to reward your efforts and perhaps twist your arm to do another ascent for a few pounds more!
Additionally, all riders will be able to purchase an FRR T-shirt at the lowest cost possible, and each shirt sold will generate a £1 donation.
Events are scheduled every 30 minutes for 24 hours beginning 7am BST May 18th (2am EDT, 11pm PDT). Events are on one lap of France’s Ven-Top route, so if you want to do multiple separate ascents you can finish the route then join the next event, which will be at most 30 minutes away.

Anyone can simply join an event, ride up Ven-Top, and make a donation via JustGiving. But if you want your efforts to count toward your Club’s totals and/or the additional carrots below, you’ll need to register with FRR (click “Register Your Participation Here” on the FRR homepage.)
If you are attempting multiple ascents as part of a continuous challenge like vEveresting, FRR says to “start one of the FRR events and just keep going, once you complete your journey send Race Control the Strava activity and we will do the rest.”
As if a good hard ride for a great cause isn’t enough, FRR has extra carrots on offer for exceptional participation:

Zwift version 1.65 begins its phased rollout today. This is a very minor update, with a few bug fixes and quality of life tweaks. See details below…
There’s not much to dig into in this update, but we’ve added a few notes in italics after Zwift’s notes below:

Wahoo’s KICKR is the most popular direct-drive smart trainer in the world, and for good reason. The latest versions are quiet, super solid, WiFi connected, and provide accurate power readings within +-1%. The KICKR’s little brother, the KICKR CORE, is hugely popular as well, especially now that it’s available as the KICKR CORE Zwift One.




While Wahoo trainers are well-built and popular, they do require calibration in order to deliver accurate power readings. There are actually three kinds of calibrations supported by Wahoo trainers, so let’s make sure we understand those first:
In the ideal scenario, users of KICKR v1-4 trainers should be able to perform a spindown calibration and see power numbers that are accurate within +-2%. Additionally, users of the newer KICKR v5, KICKR v6, KICKR MOVE, or KICKR CORE trainers shouldn’t need to worry at all about calibrating their trainers, as they’re automatically calibrated (assuming you’ve updated your trainer’s firmware to support auto-calibration, a step many KICKR CORE owners have missed).
But those are ideal scenarios. In the real world, I’ve seen perfectly functional KICKR trainers that refused to manually calibrate or auto-calibrate accurately. They would, instead, consistently read too high or too low. This includes a KICKR v4, a KICKR MOVE shipped directly to me as a test unit when it was first released, and a KICKR v6 that performed flawlessly for over a year before starting to read too high. In fact, the majority of the KICKR trainers I’ve used have needed a factory spindown performed at least once!
I’m not sure what causes a KICKR to go “out” and need a factory spindown, but based on my experience and others I’ve heard sometimes moving the trainer (picking it up, setting it down, etc) can throw things off, requiring a factory spindown before the trainer is accurate again.
When racing on Zwift I often dual-record my power data, so I can compare my trainer readings to my Assioma Duo pedals. Recently, I started noticing that my trusty KICKR v6 had started to read, on average, closer to 2% higher than the Assiomas, where in the past they had consistently been within 1% of each other.
I didn’t think much of it until the day I hopped on to ride and noticed that the KICKR was reading much higher than my Assiomas – in the neighborhood of 20 extra watts, even when I was only putting out 140W!
I let the trainer spin down without me pedaling, to trigger an auto spindown calibration, but the power readings didn’t get any more accurate even though I repeated the process several times.
Here’s what that dual recording looked like (click chart to see live data on ZwiftPower):
So I disconnected the trainer from Zwift, opened up the Wahoo app, and performed a factory spindown. Closed the Wahoo app, paired the trainer up to Zwift, and starting riding. Viola! The power was accurate once again! Here’s what that dual recording looked like (again, click for live data):

(The disconcerting thing here is that if I didn’t have a trusted secondary power source, I might have thought my KICKR’s power numbers were accurate since I was trusting it to auto-calibrate properly.)
On Wahoo’s Factory Spindown page, they say “This process is performed during production to account for very small differences in the manufacturing process and should not be done unless absolutely necessary.” They also state that “Performing a factory spindown improperly may cause harm to your device as the calibration test produces heavy drag on the unit.”
Despite these rather serious-sounding warnings, I’ve never heard of anyone damaging their Wahoo trainer via a Factory Spindown. I have, however, heard of many people fixing inaccurate power readings via a Factory Spindown!
Wahoo has hidden the factory spindown utility in its mobile app, presumably to avoid users accidentally running it. They also don’t make the support page easy to find.
So here are precise instructions for accessing and completing a KICKR factory spindown. These instructions apply to all Wahoo KICKR trainers.
You will need at least 5 minutes to complete a Factory Spindown on your KICKR, assuming you’ve already got the Wahoo app installed.
Make sure your KICKR isn’t connected to any other devices such as Zwift or your bike computer. (If another program is controlling your KICKR’s brake the spindown may not complete properly.)
This is done via the Wahoo app on iOS or Android (screenshots in this post are from iOS, Android may differ). Make sure your KICKR is powered on and Bluetooth is enabled on your phone, then from within the app tap Devices.
If your KICKR isn’t listed, tap the + to add it to your list of devices.
Tap your KICKR trainer in the device list, then tap the image of your trainer at the top of the screen 10x (or until the spindown dialogue pops up). Tap “Factory Spindown”, and start pedaling. You must do a 3-minute warmup before letting the unit spin down.




The factory spindown consists of three simple steps:
Once completed, the screen will display “Spindown Complete”, along with some stats. All done!

When asked about competitive women’s-only racing on Zwift, most people would immediately think of the Zwift Racing League (ZRL). This popular series offers women fast, electrifying racing against other women of a similar ability, while also working closely with up to five teammates to maximize the team result. For many racers, ZRL is the only women’s specific series they participate in during the year. But it only runs between the months of September and March.
Fortunately, there are a growing number of women’s only race series that could engender as much competitive spirit within the women’s community on Zwift. The recently-held Iceni Racing Series is one example. It offers women another opportunity to compete in the “off-season” in a fun, supportive environment.
So, what can you expect from a women’s race series like Iceni?

Here’s what women had to say about the racing:
“Team eSRT took part of the ICENI race series, we had a blast!
Thank you Aeonian race team for a fun well organized series! 🙂
Team eSRT had a great series, our women performed, helped and pushed eachother, fun series, great efforts and results we all can be proud off! 🙂” – Team eSRT
“Thank you Karla for including us Aussie girls this time around.. I truly appreciated it.” – Tammy (AHDRL CherryBombs)
“Just to say the eSRT ladies all enjoyed racing the ICENI series so thank you so much for highlighting and giving an opportunity to celebrate Womens racing – the livestream was exceptional and the commentary was impressive. Congrats to all riders and all involved in bringing an awesome Month of Women’s racing!!!” – Vinnette Powell, eSRT
More praise for the series:
“A Great Series, thank you Karla awesome to have such many ladies to fight with throughout the month!”
“Awesome series, cheers for putting it together! Great challenge and great competitors”
“I really enjoyed it Karla – really appreciate the effort you put in to organising and manage all the races. Great fun watching the YouTube coverage too.”

If you’re interested in joining a women’s series, please take a look at the coverage from this year, below. Join a series that works for you by clicking on the race calendar from the women’s home page.
Right now, you can find the Zwift Women’s Series, which spans eight weeks and offers multiple opportunities to race per day and a catchup day on Saturday. If you’d like to try out something like the popular weekly Team Time Trials, look into joining a women’s team.
Celebrate Ride Like King’s 16th year (and 7th year on Zwift) next week with events featuring celebrity leaders, product giveaways, jersey unlocks, and even Buffalo bikes!
Every 500km ridden by the Zwift community means one more Buffalo bike donated to World Bicycle Relief – up to 600 bikes! Read on for details…
In 2007, at age 73, Giant Group King Liu completed a 15-day, 927km ride around Taiwan. This resulted in a renewed passion for cycling and the benefits it brings to the individual, community, and country. Following this, King traveled to countries and spoke with governments to promote the positive impacts of cycling.
His message resonated within the company as well. ‘Ride Like King’ started in 2009 as a small event within the Giant Group to celebrate their founder’s passion for cycling. But it grew to be an annual event and now is in its 16th edition! Zwift is an active partner and has been hosting the event on its platform since 2018.


“Ride to Raise” warm-up rides are scheduled hourly from 6am UTC Monday, May 13 to 3am UTC Friday, May 17th. These rides rotate every other hour between two formats and have no special unlocks or prize drawings, but rides in these events (and all events in the RLK16 series) count toward our community distance goal to earn Buffalo bikes:
“Celebration Rides” are scheduled from 4am UTC Friday, May 17th to 6am UTC Monday, May 20th and include in-game kit unlocks and prize drawing entries. The schedule rotates through three blocks of events, with each block hosting 7 event time slots which are 4 hours apart:

See upcoming events at zwift.com/events/series/ride-like-king-16/
The big weekend Celebration Rides will feature pro riders from Giant and Liv’s most notable teams, including Team Jayco AlUla, Liv AlUla, Liv Factory Racing, the Giant Factory Off-Road Team, and Liv Racing Collective. Also, Giant and Liv ambassadors like Ayesha McGowan, Gustav Iden, and others will join in on the fun!
Hint: check the signup list in Zwift Companion to see who is signed up as a ride leader for any events you’re interested in!

Participate in the RLK main events from May 17–19, and you’ll unlock the exclusive Ride Like King 16 kit in game.
Also, each main event you complete earns you an entry to win a limited-edition RLK16 jersey along with a signed card by King Liu himself! Three winners will be drawing per main event, meaning 63 winners will be drawn overall.

How did you get into cycling? I engaged in handball throughout my youth and early twenties, but unfortunately had to quit due to injuries. Determined to stay active, I transitioned to cycling, initially focusing on mountain biking. As time passed, I ventured into road cycling as a pursuit for greater speed and endurance. My desire was to cover longer distances with increased swiftness. I’ve embraced triathlon now, because I find joy in the diverse challenges it offers. The combination of swimming, cycling, and running adds a refreshing variety to my fitness routine and resonates with my appreciation for variety. Despite declaring that I would never run more than 10km after I had to quit handball, this year marks a significant shift as I am preparing for my first 70.3 triathlon. I learned: “Never say never” or “I can change my mind at any time”.
How many years have you been racing on Zwift? I’ve been actively participating in racing for nearly three years now. Initially, I would occasionally take part in races, but my commitment intensified when I became a part of a team – CrushPod, leading me to compete on a more regular basis. It’s more fun suffering together – joking aside: we learn from each other, provide mutual help and support, push and encourage when needed, and even exchange baking recipes.
Are you part of a Virtual team? Yes, I joined CrushPod in August 2021. We are a women’s-only team, and thanks to the cycling tours organized by NoGodsNoMasters, many of us have had the opportunity to meet in real life.

What do you love most about racing? I have a passion for challenges, and every race presents one. It tests not only your physical and mental strength but also your concentration, endurance, reaction time, creativity with tactics, ability to endure suffering, and how well you can collaborate as a team. There’s so much more to it than simply pushing the pedals. It involves competing with others as well. Each race provides a goal for the next – to be faster, earn more points, time sprints better, and strategize attacks earlier or later. Ultimately, I aim to learn something valuable from every race.
What is your favourite style of race (e.g. points, scratch, iTT, TTT, Chase, duathlon)? The team time trials will always be one of my favourites because it aligns with what I learned with CrushPod, and since their founding, at least one team has participated in the weekly WTRL TTT. Points races are great because you have to collect FTS/FAL points, and for me, it often means pushing to the limit. In comparison, a scratch race focuses on drafting to perfection and timing your finishing sprint. In a chase race, it’s a challenge to find the team players and work together – you need to get organized quickly, and when you get caught, it completely changes. Every race category has something unique, and I can’t really decide.
What is your favourite Zwift women’s race series? It is the Tour de Boudica stage race hosted by the Warrior Games. This year, I participated in it for the first time, although CrushPod had teams competing there before. The format is great, the organization is amazing, and all the women who race in it are fantastic – there’s a great spirit from all of them.
What is your most memorable racing experience, inside or outside or BOTH? Outside: achieving victory in a 12-hour race with an all-women’s team and completing my first triathlon in Styria (where I originally come from) with a big smile. Inside: winning the ZRL with CrushPod Verdandi.
What is your favourite food to eat post race? Kefir – well, not exactly a food, but since the races are mostly in the (late) evening, and my stomach is a wetty when it comes to eating late.
What advice would you give to a woman entering her first Zwift race? Do it, and it doesn’t matter what the outcome is. Just feel the passion of racing. But what comes next? Find a team that provides a safe and fun community, so you can grow with them and step out of your comfort zone.
