Triathlon · Trail · Festival Marin County

October 3  –  4, 2026

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.

Two formats. One feeling. One weekend.

Whether the Olympic Triathlon or the Trail Half Marathon – SGRAIL Marin is an adventure you won’t forget. Race both days and earn extra awards. And bring your kids for the KIDS TRI
