MCBC 2024 DIRT FONDO – DEPARTS FROM The Marin Headlands, Saturday, July 20!
The 12th annual MCBC Dirt Fondo returns for another year of outdoor off-road adventure! Join us on Saturday, July 20, 2024, as 300 lucky riders will embark on a 45-mile journey from the Golden Gate to Mt. Tam and back. There is amazing scenery along the whole route and a good mix of trails, fire roads, and tarmac! Friendly faces will greet you at 4 rest stops on the way out as well as on the return and world-class support on course, including marshals, mechanics, and SAG.
The day culminates with a post-ride party among the horses at the Presidio Riding Club Stables in the Marin headlands.
When: Saturday, July 20, 2024 (soft start between 6:30 a.m. and 8:00 a.m.)
Where: Rodeo Valley Trailhead at the Presidio Riding Club Stables in the Marin Headlands
While the Dirt Fondo started as a mountain bike event, run what ya brung (aka Gravel, Cyclocross, or Single Speed)!
The classic route takes riders from the Marin Headlands to the top of Mt. Tam and back on a crisscrossing selection of trails and fire roads.
45, 32, and 24 mile options // Post-ride meal // Well-stocked energizer stations // Dirt Fondo Schwag // Course Marshals & Sweeps // SAG & radio support // Much more…

Traditional Territory of the Coast Miwok
As you enjoy the trails in Marin, please remember that you are riding within the traditional territory of the Coast Miwok, many of whom are now citizens of the Federated Indians of Graton Rancheria. Please help us acknowledge the Tribe and their continuing legacy as caretakers of their ancestral territory. Do your part to not disrupt the landscape by staying on the trail.
Dirt Fondo FAQs
Can I do these routes on a gravel bike?
All Dirt Fondo routes are planned with mountain and gravel bikes in mind. Upright bars and suspension will have advantages on the trails and rutted fire road segments, but a gravel bike is great for the smoother fire road bits and road segments. Either way, be prepared for some challenges along the way and walk tough sections if it looks too difficult – no one will judge you!
Are e-bikes allowed?
All routes cross multiple parks and e-bike regulations are not consistent from agency to agency. See our stance on e-bikes, and where you can ride them, at https://marinbike.org/resources/e-bike/
