SURF is a non-profit organization committed to serving the needs of the San Diego trail and ultra running community. SURF is dedicated to fostering positive growth in the community through education, athlete engagementlocal race support, and trail maintenance. Whether you’re fast or slow, younger or older, if you love to run long and on trails or just starting to run, you’ll want to join the SURF community 

    So why support SURF by joining?

    Without your support, a huge number of trails in our San Diego mountains would become impassible, like trails at Mt Laguna, Cuyamaca, and along a large section of the PCT. Through our TrailFit initiative, we respond and fix trail problems and conduct regular upkeep.
