Miwok 100K

The course covers about 62 miles of single-track and dirt fire road, with roughly a mile of pavement and more than 11,000 feet of gain. It starts and finishes at the Stinson Beach Community Center, climbs the Dipsea Trail in the dark, and heads south through Muir Beach and Tennessee Valley toward the Golden Gate before turning back north.

The second half climbs past Pan Toll to Bolinas Ridge, drops to Randall Trailhead at mile 49, and returns on the technical Matt Davis Trail. Intermediate cutoffs are enforced at aid stations including Tennessee Valley, Muir Beach, Cardiac, Randall and Bolinas Ridge, and the overall limit is 15 hours 30 minutes.

Miwok 100K has run out of Stinson Beach, just north of San Francisco, for about three decades and is now presented by The North Face. The field is capped at 400 runners, and the race sells out quickly.

The event is cupless and low-waste, offers a four-person relay alongside the solo race, and is a UTMB Index race and a Western States qualifier. Volunteers who work at least eight hours earn priority entry for the next year.
