This workout is designed to improve leg speed and increase the efficiency of your fast-twitch muscle fibers, which contributes to overall aerobic development. Power will be low but leg speed will be high keeping a higher demand on your cardiovascular system. If you're unable to hit the target cadence, simply hold the highest cadence you can for the full duration of the interval. Alexey Vermeulen is a Wahoo-sponsored athlete who brings energy, versatility, and a fresh perspective to the gravel scene. After racing in the World Tour and chasing results in Europe, he's found his stride in the U.S. gravel and off-road world — where the racing is hard, the community is tight, and the vibe is all-in. Known as much for his performance as his personality (and for occasionally racing with his dog, Sir Willie the Weiner), Alexey trains and races with Wahoo tech to stay ready for anything - from high-altitude climbs to unpredictable gravel conditions. He's all about pushing limits while keeping it fun. Stay up to date with Alexey's adventures on Instagram.
