BayTrailrunners

We are a homegrown, grassroots running community that was founded locally in the foothills of the Santa Cruz Mountains and the Marin Headlands. We meet regularly for fun, noncompetitive and social group trail runs in and around the San Francisco Bay Area. There is no cost to join! Check the calendar, bring a friend, and enjoy some of the best trailrunning on the planet!
