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.

Message of Jan Frodeno to you

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
