The 2014 Miwok 100K 

What a race! After a few years of last-minute changes, the 2014 Miwok 100K was the course we had all been looking for. Marin County got some much-needed rain in the week prior to the event, averting any drought-related course alterations. The temperature and the wildflowers cooperated, and even the poison oak kept its tendrils off most of the trail. The Trails in Motion Film Festival organized by Robert Rhodes at Sports Basement in San Francisco on the Wednesday before Miwok put everybody in a great mood. How can you not be inspired watching Ryan Sandes, Seb Chaigneau, Kilian Jornet, Krissy Moehl, Dakota Jones, Tony Krupicka, Scott Jaime, and some of the other greats strut their stuff on epic trails around the world? We were ready – for steep climbs, gorgeous views, hot competition and cool ocean breezes – and the Miwok runners delivered. About 450 runners checked in on race morning, with 357 crossing the line at the end of the day. Helping them on their way were over 130 volunteers, who took care of race week tasks from Costco to course marking to cleanup, and everything in between. Huge thanks go to all the volunteers, and our Captains:
  • Course-marking: Florencia Gascon-Amyx
  • Bolinas Ridge: Ana Braga-Levaggi
  • Randall: Chuck Wilson
  • Cardiac: Alex Varner and Jorge Maravilla

For those of you planning to use the Miwok 100K as a UTMB qualifier, the UTMB Qualifying Race system changed on April 17, 2014, now requiring stacks of paperwork and a sizable chunk of euros; certification is in progress.

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 Muir Beach in the evening), so remember to bring your own. The entry lottery will open at Ultrasignup.com in early December and you’ll have one week to put your name on the list. Please check back in late September for the exact lottery dates.


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.
