Put money on your training. Stake on hitting each session, get paid when you finish, and let your stake go to the athletes who show up. Cadoo verifies every workout — so the results are real.
Everything you need to plan your build-up. Details below are for the event itself; the training happens on Cadoo.
This is the home for Mount Desert Island Marathon training games on Cadoo. As branded games and event skins go live, they will appear right here.
For an event like this, Cadoo runs a Pace Challenge game — it locks you into goal-pace efforts so race pace feels automatic on the day. Every rep, mile, and minute is verified: reps by CadooVision's AI camera check, steps and distance via Apple Health or Google Health Connect. The money only moves on work you actually did.
The full write-up: how the Pace Challenge game maps to race day.
Every marathon, ultra, tri, bike race, walkathon and duathlon on Cadoo.
