Your Trail Warrior plan for the Miwok 100K

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.

Trail Warrior

For an event like this, Cadoo runs a Trail Warrior game: it builds the specific fitness this event demands, one steps or camera-reps session at a time. Cadoo verifies camera reps and device steps. It does not time the course, and this race does not pay a cash prize.
