2027 Stinson Beach / Muir Woods Marathon, Half Marathon & 7 Mile
The event takes place on May 8, 2027 at the Stinson Beach Parking Lot in Stinson Beach, California. It is limited to 300 participants and offers three distances.
- Marathon
- Half Marathon
- 7 Mile
The course is a trail route that leaves sea level at the start and climbs into the wooded trails of Muir Woods via the Dipsea trail to Steep Ravine. The route includes a wooden ladder, natural rock and wooden staircases, and stretches where runners must scramble under tree trunks. Participants 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 course will be marked with orange ribbon. Seven milers turn at the first aid station; half marathoners and marathoners complete a loop, with marathoners repeating the loop and adding an out and back that is signed at the turnaround. Aid stations are located at miles 3.8, 7.5, 10.5, 14.2, 17.2, and 22.2; carrying water is recommended. The course cut-off time is 6.5 hours. Hikers and walkers are welcome.
Bibs are mailed beginning two weeks before the event; participants who do not receive a bib may pick one up on race morning at the start/finish area where safety pins and course maps are available. Parking is available at Stinson Beach Park. For safety reasons, headphones and other audio devices are not allowed. Registrations are non-refundable and non-transferable; if refund protection was not purchased, cancellations by April 8, 2027 may receive a rollover credit minus a $20 fee.
