Whether you’re a seasoned mountain biker or a gravel-curious adventurer, this event offers a unique way to explore the region’s natural beauty while supporting a great cause.

Riders can choose from 45-, 32-, or 24-mile route options, each winding from the Marin Headlands to the trails of Mt. Tam and back. Expect a satisfying mix of trails, fire roads, and tarmac - all with world-class ride support. Along the way, you’ll be cheered on by friendly volunteers, refuel at four energizer stations, and benefit from course marshals, sweeps, and SAG support.

The day wraps up with a festive post-ride party at the Presidio Riding Club Stables, complete with delicious food, community vibes, and plenty of dirt-earned high fives.

This ride is more than just a challenge; it’s trail advocacy in motion. Proceeds benefit MCBC’s efforts to expand trail access, equitably share open space, and inspire the next generation of riders.
