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 Born to Run Ultra 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 Night Runner game — it gets you comfortable moving after dark — essential for 100-milers that run through the night. 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.
