About the Miwok 100K

The Coast Miwok

The Miwok 100K got its name from one of the main trails of the early course. The trail was named afer the original Indigenous stewards of Marin County, who settled the land at least 10,000 years ago. (In typical colonizer fashion,“Coast Miwok” is the name assigned these first caretakers. “Huuku’i’ko” is what the First Inhabitants of this area called themselves.) Abalone, salmon, acorn flour, wild strawberries, edible forbs and corms: while nature’s menu varied from one season to the next, under the attentive management of the Huuku’i’ko, it was almost always abundant.

Tragically, the invasion, first, of Spanish missionaries in the early-1700s, then, of white colonizers, destroyed almost 95% of the tribe within just 200 years. Despite it all, the descendants of the First People are still here. We are grateful to the Coast Miwok (Huuku’i’ko) for their reverence for the land on which we run. We feel an obligation to care for this land so future generations can walk here in peace and beauty.

If you’d like to know more about the people whose ancestral home is this stunning area, visit www.coastmiwokofmarin.org. This website will give you an extra appreciation of the region and its Native American inhabitants today as you traverse its trails. And as you run Coyote – one of the many trails that comprise the Miwok 100K course – be aware there are many Coast Miwok stories about Oye (Coyote), a much-loved trickster. So remember to watch your step.

History

Since its inception in 1996, the Miwok 100K has been defined by an unbroken line of female leadership. Visionary Kellie Sheehan launched the event, and that tradition was proudly carried forward by Tia Bodington starting in 2004, and is now championed by Magda Boulet who took the reins in 2023. What began as a humble race with 69 starters has blossomed into a world class event celebrated for its deep commitment to sustainability, inclusivity, and unwavering sense of community. This inspiring continuity has guided the Miwok 100K through necessary course evolutions—including the significant 2012 move to the iconic Stinson Beach start and finish—always adapting while holding fast to its core values.

Sustainability & Community

For over a decade, the Miwok 100K has led the way in sustainability—pioneering recycling, composting, and a cup-less race since 2013. Leftover food is donated to local shelters.

We are a proud business member of 1% For The Planet and Leave No Trace , and partner with GU Energy Labs to TerraCycle all sports nutrition packaging.

Our Miwok 100K Bridge to Trails Initiative, launched in 2020, focuses on improving inclusion, visibility and access in trail running for Black, Indigenous, and People of Color. To partner or learn more, contact Magda Boulet, RD at miwok100k@gmail.com

Race Director – Magda Boulet

Magda Boulet carries forward the legacy of Tia Bodington, who grew up on the trails of Mt. Tamalpais, ran her first Miwok 100K in 2000, and helped shape the race as Race Director. Tia’s adventurous spirit from Western States to Badwater and UTMB continues to inspire the Miwok community today.

Following in those footsteps, Magda, a U.S. Olympic marathoner, earned her spot on the 2008 U.S. Olympic Team with a second-place finish at the Trials. A native of Poland who became a U.S. citizen on September 11, 2001, she holds a bachelor’s in Human Biodynamics from UC Berkeley and a master’s in Exercise Physiology from Cal State Hayward.

After conquering the marathon, Magda found a new challenge on the trails. In 2015, she won the Western States 100 and went on to victories at Leadville 100 and the Marathon des Sables. She lives in Oakland, California, with her family, running the Bay Area trails and leading GU Energy Labs in Berkeley.
