Train for the Chicago Marathon with Cadoo
The Chicago Marathon is a Marathon in Chicago, IL on Oct 11, 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 Negative Split Trainer training game
For an event like this, Cadoo runs a Negative Split Trainer game — a 16-week plan pitched at difficulty 7/10. It trains you to finish faster than you start — the hallmark of a strong race. 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 #MileageClub, #RoadWarrior, #PRHunter.
