About the Mt. Tam Trail Run
The course starts at Stinson Beach and goes up, steadily and seriously, to the high ridgeline of Mt. Tamalpais. The views from the top are wide and open. The return brings you through Headlands trails before dropping back to the beach, so the finish feels earned in a way that flat courses rarely do.
Parking is in the Mt. Tam State Park and Muir Woods National Monument area. Post-race, there is food at the beach, and the setting makes it easy to linger with whoever came out to watch.

The Mt. Tam Trail Run has been held every year since at least 2022. That is as far back as RunSignup's records for this race go, so it may well be older.
How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Sep 22, 2026.
