About the Stinson Beach/Muir Woods Marathon
Enviro-Sports' Stinson Beach/Muir Woods race is a destination trail marathon rather than a mass road event, capped at a small field on classic Marin terrain.
Course
The trail route climbs from Stinson Beach into Muir Woods, uses Dipsea and Steep Ravine terrain, and sends marathoners through repeated technical sections.
Race-day weather
May near the coast is often cool, but exposed climbs can warm quickly. Trail shoes, water, and comfort on stairs matter more than road-race splits.
