Tamarancho Dirt Classic – 511 Contra Costa

Tamarancho Dirt Classic

Tamarancho Dirt Classic is the only Cross Country Mountain Bike race in Marin County! Mostly technical single-track with a few fire road climbs and lots and lots of vertical feet of climbing. The race benefited the NorCal High School MTB league and the new Off-Road Advocacy Program of the MCBC. Others benefiting include Stafford Lake Bike Park and Access4Bikes.
