Pro Cyclist to Trail Runner: Physiologist Noah Collins on Starting Over

Noah Collins is an exercise physiologist, a former Category 1 road racer, and the founder of the endurance coaching company RyseOn. He has worked as head physiologist for Carmichael Training Systems and Zwift.

In this conversation, Zoe and Brendan talk with Noah about the IMAX documentary that hooked him on cycling in seventh grade, finishing dead last every week of his first time trial series (with ice in his hair), and why he sold six of his seven bikes. Then he explains why so many retired cyclists end up on the trails, why he coaches by time instead of mileage (including the client who ran laps of a parking lot to hit an even number), and what research on the gut microbiome might say about motivation to exercise. Plus, Zoe picks a bar fight over sweet spot training, and Noah offers one very practical sign that you're taking too many supplements.
