Train for the Western States 100 with Cadoo
The Western States 100 is a 100 Miles Ultra in Squaw Valley, CA on Jun 27-28, 2026. Signing up is the easy part — showing up for every training session until race day is where most people fall off. Cadoo fixes that by turning your build-up into a money-motivated game: stake money on hitting each session, hit your goal and get paid, miss it and your stake goes to the athletes who showed up.

Your Night Runner training game
For an event like this, Cadoo runs a Night Runner game — a 28-week plan pitched at difficulty 10/10. 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, distance and steps via Apple Health or Google Health Connect), so the money only moves on work you actually did.
Built for training crews like #UltraGrit, #TrailBeast, #ElevationGain.
