A New Way for Serious Cyclists to Train Indoors This Winter

Wahoo’s long-awaited revamp of The Sufferfest endurance training app makes room for a whole lot more than suffering.

Confession: I never used The Sufferfest, a popular cycling training app that encourages users to apply maximal effort as they pedal through streaming workouts in the make-believe world of “Sufferlandria” on their stationary bikes. Being Outside on my mountain bike is my preferred training platform. Plus, I had the notion that The Sufferfest was geared toward ultra-competitive, sweaty cycling dudes battling it out on their trainers, which is sort of true. As its founder David McQuillen, a cyclist and former banker now based in Tasmania admits, the platform was “overly masculine.”

It was also, however, highly regarded for the sport science it brought to a training platform. So when I heard the news that Wahoo Fitness bought The Sufferfest in 2019, took two years to expand on the science, added a fully comprehensive tool kit beyond cyclingâ€"with components like yoga and mental toughness sessionsâ€"and changed the name to the more palatable SYSTM, I became intrigued.

The newly revamped training platform is being unveiled today, and I got the chance to take it for a prelaunch spin. The good news: The new SYSTM kept me fully engaged inside on a trainer during a week of gorgeous fall weather.

The standout feature of the redesigned app, whose target audience is endurance athletes, is how deeply it dives into science to analyze your performance in the saddle. Headed up by Neal Henderson, the Boulder, Colorado-based coach to Olympic champions like Flora Duffy and many others, Henderson’s theory is that a traditional functional-threshold-power-based workout, which is an athlete’s ability to sustain the highest possible power output over the course of 45 to 60 minutes, isn’t enough to train effectively. To improve upon it, he developed "four-dimensional power" (4DP) which, in addition to FTP, uses neuromuscular power, anaerobic capacity, and maximal aerobic power to devise a more efficient, finely tuned, and customized workout.

To find that magic 4DP while using the app, athletes work up to the hour-long Full Frontal ramp test, an all-out, guts-on-the-ground effort. Once the test is complete, the app will customize a training plan going forward tailored to each specific athlete's profile.

This all may sound too serious. Science and suffering aside, however, SYSTM is also a fun, educational, entertaining, and comprehensive cross-training platform that doesn’t take itself too seriously. It has five components: Cycling, Running, Swimming, Strength, Mental Training, and Yoga, all of which can be coordinated together in one place on the app’s easy-to-use calendar.

The device-agnostic SYSTM is available for Mac, PC, iOS, and Android devices. Since the app can be cast to a television or simply run on a phone or tablet, it's compatible with Wahoo trainers and bikes, as well as bikes from other brands.

I focused on Cycling, a catalog of dozens of rides broken into five major categories. On Location is set in stunning environs. I liked the sound of Getting Away With It, a 44-minute effort. The goofy story line starts you at the office, where, after telling the boss a few little white lies, you miraculously make your way to a mountain road in the Pyrenees to climb 2,200-meter Arcalis and other passes with pro cyclist Dan Martin and Mike Cotty, founder of The Col Collective. The Spanish scenery is augmented by commentary from the guides, a tempo-appropriate playlist, nuggets of regional history and culture, cycling prompts that pop on the screen like “stand up,” and a litany of goofy jokes about the “Couchlandrians” back at the office. Spoiler: The boss ultimately catches on and you’re fired. There’s a lot going on, but it felt like a challenging ride while engaged with friends having fun rather than slogging it out in isolation wanting to slay the virtual opponent from the UK who keeps passing me, as is the case with other platforms I’ve used.

The next category is the A Week With rides that are centered around cycling celebrities who show you how they train. I spent a day (or rather a 48-minute session) riding around the Boulder Velodrome with Neal Henderson, an activity I would not likely pursue in reality, considering it involves riding on a banked race track in close proximity with others on bikes without brakes. Pro Rides consist of real footage from the World Tour, along with a power file from a pro athlete that is scaled to your own 4DP. There are also Novids, a set of over 100 workouts with only text commands rolling on the screen; and indoor cycling classes led by favorite instructors from the Global Cycling Network. The app also has a catalog of more than 50 cycling films, stories, and documentaries, like Rising From the Ashes, a powerful 2012 documentary about the Rwandan cycling team, to increase the stoke.

I also explored a 15-minute basic yoga class tailored specifically for cyclists that even my stretching-phobic partner Brian would enjoy. The yogini’s mellow Aussie accent and easy-to-follow instructions were a relaxing oasis of calm in a hectic day. Then I tuned into the 14-minute "Getting Positive” video, one of 20 episodes over a 10-week series, designed to improve athletes’ mental fitness. I had to laugh: This particular episode used the example of how the brain often goes to dark and negative places after you drop to the back of the pack on a group ride, a sensation I have experienced. This program gives athletes the tools to visualize turning that negative energy into a positive outcome.

In my few weeks of playing around with SYSTM, my take is that it’s targeted toward serious amateur athletes who want more than a spin class but don’t have the funds or time to commit to a personal coach. There are whole categories, like Strength, Swimming, and Running, that I haven’t tapped into yet, but I’m in it for the long haul. There’s a long winter ahead.
