Welcome to San Diego Ultra Running Friends (S.U.R.F.)! We are THE 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.
Please read the latest news from the Cleveland National Forest on what is open and what is closed in our local mountains.
We’d love to run with you. Whether you’re fast or slow, younger or older, if you love to run long and on trails or just starting to think about it, you’ll want to check out the SURF community!
