Dirt Fondo – Marin County Bicycle Coalition
August 8 @ 12:00 pm
Join MCBC’s Annual Dirt Fondo for a breathtaking ride in the birthplace of mountain biking.
Dirt Fondo 2026 is back for another year of outdoor off-road adventure! Mark your calendar for Saturday, August 8, 2026, as 300 lucky riders will embark on a 43-mile journey from the Golden Gate to Mt. Tam and back.
More than a ride, Dirt Fondo is a day of testing your limits and celebrating the trails that make Marin legendary. Enjoy amazing scenery along the route and a good mix of trails, fire roads, and tarmac.
Every mile supports MCBC’s work to expand trail access, empower new riders and trail stewards, and protect the wild places we love to ride.
