Miwok 100K

Miwok 100K

The Miwok 100K is one of the most beautiful and iconic trail ultramarathons in the world. The course is hilly (11,800 feet of gain) but runnable, with spectacular views of San Francisco and the Golden Gate Bridge, Sausalito, Mount Tamalpais, the ancient redwoods and the Point Reyes National Seashore. The course features single-track trails and dirt roads with about a mile of paved road. The race is competitive at the front, and a rewarding challenge for all. Less than an hour from San Francisco, the Start/Finish is in the town of beautiful Stinson Beach, nestled against Mount Tamalpais, with its excellent cafés, a small market, lodging, and more. Course marking is excellent, and you’ll be supported by some of the best volunteers on a race course anywhere. We hire professional medical for all aid stations for those occasional skinned knees and such. Our 2026 runners will receive a custom Miwok 100K finisher’s medal and a Miwok 100K mug.
