Choose your teammates, review the legs, and start talking about who’s running where. Even the shortest leg brings plenty of climbing!

Epic views and plenty of vertical gain are huge part of the Miwok 100k, and we encourage you to really think about what it means for you.

Steep climbs, exposed ridges, and changing coastal weather are all part of the experience, along with tight cutoffs that will require thoughtful pacing and clear strategy from the start.

Preparing means building climbing strength, getting comfortable on technical trails, practicing your fueling and learning how to manage a long day outside.

Before registration opens, review the course and cutoff times alongside your experience and training plans. Give yourself an honest picture of what it will take to arrive ready.
