Stinson Beach/Muir Woods Marathon, Half Marathon & 7 Mile

This trail event starts at Stinson Beach Park and climbs into the wooded trails of Muir Woods. The route follows the Dipsea trail to Steep Ravine and includes a wooden ladder, natural rock and wooden staircases, and sections that require scrambling under tree trunks. Runners pass brooks and waterfalls and run among towering redwoods and oaks before reaching a summit with panoramic views and descending back to Stinson Beach. The event is limited to 300 participants.

Distances

  • Marathon: full distance with two loops and an additional out and back turnaround.
  • Half Marathon: one loop following the same route as the marathon.
  • 7 Mile: shorter out and back that turns at the first aid station.

The course is marked with orange ribbon. Aid stations are located at miles 3.8, 7.5, 10.5, 14.2, 17.2, and 22.2; carrying water is recommended. There is a 6.5 hour course cut off; hikers and walkers are welcome. Bib numbers are mailed beginning two weeks before the event; participants who did not receive a bib can pick one up on race morning at the start area. Parking is available at Stinson Beach Park. For safety on narrow trails with steep drop offs, audio devices and headphones are not allowed. Visit the organization's website for the most recent information.
