2026 Dirt Fondo
August 8
The 14th Annual of MCBC’s Dirt Fondo returns for a day of off-road adventure on Saturday, August 8, 2026. Register here!
Choose from 3 different routes – 43 miles, 32 miles or 24 miles – and join 300 lucky riders as you embark on a journey from the Golden Gate to Mt. Tam and back.
It’s a breathtaking experience in the birthplace of mountain biking. And every registration supports MCBC’s work to expand trail access, empower new riders and trail stewards, and protect the wild places we love to ride. Sign up today!
All proceeds support MCBC’s Off-road program. If you have any questions, please contact Sandy Allen.
We can’t wait to see you and celebrate 14 years of off-road adventure at the Dirt Fondo!
