SAN FRANCISCO BAY AREA TRAIL RACING

BayTrailrunners is a homegrown, grassroots running community that was founded locally in the foothills of the Santa Cruz Mountains, the Marin Headlands and the San Francisco Bay Area's Mid-Peninsula.  Not only do we host some amazing trail races, but we also meet regularly for fun, noncompetitive and social group runs. Check the calendar, bring a friend, and enjoy some of the best trailrunning on the planet!
