This is the home for Chicago 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 Negative Split Trainer game — 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, steps and distance via Apple Health or Google Health Connect. The money only moves on work you actually did.
