Miwok 100K

The Miwok 100K is a 62-mile ultramarathon through the Marin Headlands just north of San Francisco, featuring over 11,500 feet of elevation gain across some of the most diverse and dramatic terrain in California. Runners start and finish at Stinson Beach Community Center, winding through coastal redwood forests, exposed ridge lines above the Pacific, and historic fire roads — all within the Golden Gate National Recreation Area. The race features nine aid stations, drop bags at Tennessee Valley (miles 13 and 26) and Randall Trailhead (mile 49.2), and crew access at three points. Pacers may join at Randall, with 13 miles to go. Now presenting-sponsored by The North Face, the event has been defined since its 1996 founding by strong community roots, sustainability leadership (cup-less since 2013), and a commitment to trail stewardship. Tight intermediate cutoffs — required by California State Parks permit — demand consistent pacing throughout.
