The Miwok 100K is entering a new chapter as the Miwok 100K Presented by The North Face.

For nearly 30 years, Miwok has been defined by challenging trails, deep community roots, and respect for the land on which we run. Partnering with The North Face allows us to build on that legacy, with a shared commitment to stewardship, storytelling, and inclusive trail running beyond race day.

We’re grateful to the community, volunteers, and runners who make this event what it is, and we’re excited about what’s ahead.

The Course

Set in the Marin Headlands just north of San Francisco, the race offers 62 miles of gorgeous trails, over 11,000 feet of gain, and nonstop views, from redwoods to ridge lines to crashing coastal cliffs. Learn more about the cutoff times and course

Who should run Miwok 100K presented by The North Face?

This race is for runners who:

• Embrace steep climbs, exposed ridges, and fast-changing weather
• Have experience with trail ultras and self-supported effort
• Respect the land and leave no trace
• Can stay ahead of tight intermediate cutoffs (to ensure safety and meet permit requirements)

You don’t need to be elite. But you do need to be prepared.
