The San Diego Mountain Biking Association is a 501(c)3 Nonprofit

Our work is supported by generous donors like YOU!  

We are gearing up for a very busy 2022-23 Trail Work season on projects throughout the county from Mount Laguna to Daley Ranch to Chula Vista, Penasquitos and more!  When you donate to this general fund, we promise to use your gift where it's needed most.  Whether that's covering operating costs, clearing a fallen tree,  or buying lumber for a new bridge or a shovel for a volunteer to use, we'll make sure your money has the most impact on our trails and our community.  

Past contributions and grants have allowed us to purchase and maintain a mini-excavator, a motorized wheelbarrow, a plate compactor, a water buffalo and water distribution equipment,  and loads of hand tools and materials to help us maintain and build trails.  In addition, your support provides resources for our staff and our volunteer trail experts to partner with user groups, land managers, and policymakers to improve access and your trail experience.  Learn more about current projects here past projects here.
