About this race
The Miwok 100K, a trail ultramarathon in the Marin Headlands, starts and finishes in Stinson Beach with Mount Tamalpais as a backdrop. The course features redwoods, ridge lines, and coastal cliffs, mixing single-track, dirt roads, and some paved sections. Runners will receive excellent support and earn a custom finisher’s medal and a sweatshirt.
