To limit the spread of the novel COVID-19 pandemic and prioritize the health of our community, our team is canceling all events for the foreseeable future, including trail work days, community meetings and events. We have also closed registration for the Archipelago Ride as we monitor this public health crisis.  We will provide updates on  the Arch Ride in a few weeks to current registrants and volunteers.  

Our thoughts are with everyone around the world that is currently affected by this virus, and we wish all a speedy recovery. 

Check our Trail Etiquette page for links and updates at federal, state, and local open spaces, parks, and trails.

Celebrating 25 years of improving trail access for mountain biking in San Diego County

Over 1400 members have stepped up to help SDMBA make mountain biking better for everyone in San Diego County. SDMBA advocacy volunteers provide a unified voice for trail users in public land use policies favoring sustainable outdoor recreational opportunities. Liaisons, trail builders, and other advocates seek out and build harmonious unified alliances and partnerships with businesses, land managers, and communities. Specialized volunteer-run programs support this mission and further inspire youth to explore and learn about nature and become its future stewards.

Got Trail Work?  We do!  Volunteers needed.  Check all opportunities on our Event Calendar.
