Welcome to the 21st Annual Miwok 100K!

  • May 7, 2016 – 5:00 a.m. – Stinson Beach, California • 

A big thanks to everyone for participating in the 2015 Miwok 100K on May 2, 2015. On behalf of all the volunteers, spectators and sponsors, I’d like to congratulate you on meeting the challenge, or giving a great effort in the attempt. The weather was perfect for a long run, the wildflowers were out in abundance; I hope you all enjoyed the mysterious bagpiper at Cardiac, and our race pirate near the Pelican Inn. We had some top-notch competition and quite a few PRs this year and will endeavor to keep exactly this course for years to come, with cutoffs adjusted to reflect this year’s splits. Over $600 in proceeds from the sale of  “vintage” Miwok 100K shirts, hats and blankets will be donated to the Himalayan earthquake relief fund, and leftover food donated to a local Food For Families organization.   Our 2015 Captains and Clubs:

The Miwok 100K is a cup-less race. 2016 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 2015 volunteers (8 hours) will receive an extra ‘ticket’ into the 2016 Miwok lottery, and many volunteers get into the following year’s race.  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. Tia Bodington, Race Director
