This is the home for Naperville 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 Distance Countdown game — it counts down the long runs to race day so every week has a clear, escalating target. 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 Distance Countdown game maps to race day.
Every marathon, ultra, tri, bike race, walkathon and duathlon on Cadoo.
