Dirt Fondo MTB Riders

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…

The ride begins at the Presidio Riding Club stables at 901 Bunker Road in the Marin Headlands with a soft rollout between 6:00 a.m. and 8:00 a.m. on Saturday, July 20, 2024. There is ample parking across the street, but please carpool if possible.

Dirt Fondo FAQs

What are the routes?

45 Mile Route – https://www.strava.com/routes/2984701028511893140

32 Mile Route – https://www.strava.com/routes/2984700821142326932

24 Mile Route – https://www.strava.com/routes/2984700611796093588

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?

The 32 and 24 mile options are e-bike legal. The 45 mile route includes the Mt. Tam Watershed, which currently considers the e-bikes motor devices, which are prohibited. They will likely be allowed under a pilot program by the July 20 event, but no guarantees. See our stance on e-bikes, and where you can ride them, at https://marinbike.org/resources/e-bike/
