One day, three sports, nine ways to suffer well. The All For 1 Endurance Challenge sends gravel riders, trail runners and dual-sport motorcyclists into the Sierra foothills above Nevada City — each on their own course, all chasing the same finish.
Every entry supports two local and international charities. Ride hard, run far, twist the throttle — and make it count for somebody else.
Pick your poison
Scenic. Gritty. Unforgettable.
Mostly dirt. All epic.
Rugged trails. Elevate yourself.
Wild. Beautiful. Unrelenting.
Dual-sport paradise. Ride harder.
Technical. Remote. Legendary.

November comes fast.
In the price
Not racing this year?
A day this big runs on volunteers. Aid stations miles from the nearest road, marshals at the junctions that matter, hands at the start line, and a sweep riding in behind the very last athlete — none of it happens without people willing to give a Saturday.
You get the best seat in the house: the sharp end of the course, and the moment somebody finishes a thing they weren't sure they could. Same mountains, same community, same two charities — no entry fee, no training block. Crew call is 6:00 am, an hour before the first athletes roll out.
Where we need people
Medically trained? EMT, paramedic, nurse, physician, PA or NP — choose AF1MedSupport instead.
On BikeReg, choose AF1Ambassador — it's free, and we'll be in touch about where you're needed.
