The Miwok 100K is a cup-less race. 2015 Entrants must each bring their own cup to use at aid stations. There will be no paper cups on the course. Start/Finish will once again be at the Stinson Beach Community Center nestled against Mount Tamalpais in the town of beautiful Stinson Beach, with its excellent cafes, a small market, lodging, and more. The Miwok 100K is very hilly (approximately 11,800 feet of cumulative elevation gain) with spectacular views of San Francisco  and the Golden Gate Bridge, Mt. Tamalpais and the Point Reyes National Seashore. The course features fire roads and single-track trails with less than a mile of paved road. The race is very competitive at the front, and a rewarding challenge for all. There is fantastic post-race food, a tech-fabric race shirt and goodie bag with useful, ultra-specific items from our outstanding sponsorsMiwok is a cup-free race (except at the finish, and for soup at Randall in the evening), so remember to bring your own.


Miwok is a lot of fun to run, and volunteering at the race can also be a blast. You meet great people, help your community, and get food and some cool swag, too. It’s also a good way to learn about ultrarunning and improve your own performance by observing a lot of runners’ pacing and aid station strategies. All 2014 volunteers (8 hours) will receive an extra ‘ticket’ into the 2015 Miwok lottery, and many volunteers get into the following year’s race. All 2015 volunteers get the same deal!
