Registration For the 2021 Miwok 100K

Due to the “covid-cancellation” of the 2020 Miwok 100K, we did not use a lottery for the 2021 event. Registration for the 2020 entrants was on Ultrasignup.com November 1 through November 7, 2020. On November 8th, registration opened to fill the remaining spots.

We’re looking forward to an amazing race day, and our 25th anniversary of this epic event.


The top three men and women will each receive a special award. Age group awards will be given to division winners in the following:

Men and Women: 18 – 29, 30 – 39, 40 – 49, 50 – 59, 60+

Goodie Bags

Miwok race finisher pewter medal

All participants receive a goodie bag with great stuff from our sponsors, along with a top quality, run-in-rabbit tech shirt (men’s and women’s sizes) and our traditional custom pewter finisher’s medal.


Assuming that we get the go-ahead in January from the State of California and Marin County, to hold a running event in May, the 2021 entrant list will be posted here as soon as everyone who signed up has confirmed their registration.
