The race

SGRAIL is so much more than a triathlon. Expect the beauty of Marin County — the Bay, the Golden Gate and China Camp State Park — varied courses and aid stations with real character, combined with community events: a sporty warm-up, great local food and meeting your fellow SGRAILERS. At SGRAIL it’s not about the clock – it’s about the experience, good food and the moments you share.
