Welcome to the 20th Annual Miwok 100K!

The 20th annual Miwok 100K will take place on the first Saturday in May, 2015

If you’d like to volunteer, email the RD at miwok100k@gmail.com

  • May 2 – 5:00 a.m. – Stinson Beach, California • 

The 2015 course will be run on the same trails as the 2014 course, but we’ll run the South loop (toward the Golden Gate Bridge) first and then the North loop (toward Olema). The park services prefer this direction since it lets runners complete the busier trail sections earlier in the day. The runners will love this direction because there is room to spread out before hitting the narrow single-track, and the tougher series of hills will be done by mile 40 or so. Please review the Mileage Chart for the revised data, and take note of the new cutoff times.

The Trails in Motion Film Festival organized by Robert Rhodes is slated for Thursday, April 30, 2015. Go to Ultrasignup to get your ticket! Miwok runners get a 20% discount; email the RD for the discount code

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 a fantastic post-race barbecue, great 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 bbq, 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! Check out the Volunteers link to see what you can do and send me an email at Miwok100k@gmail.com. If you cannot find the answers on this website, please feel free to e-mail me with any questions.
