Welcome to SURF

The mission-driven community for all things ultra-running in San Diego County

Welcome to San Diego Ultra Running Friends (SURF)

SURF is the mission-driven community resource for ultra running and trail running in San Diego.

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 engagement, local 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.
