Your Night Runner plan for the Western States 100

Cadoo verifies the work before race day: camera reps and device steps. It does not time the course. Open the Ultra & Trail Arcade: Cadoo to pick this event and start a train-for game.

Night Runner

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. Cadoo verifies camera reps and device steps. It does not time the course, and this race does not pay a cash prize.
