Registration For the 2021 Miwok 100K

Due to the “covid-cancellation” of the 2020 Miwok 100K, we will not use a lottery for the 2021 event. Spots will be filled first-come, first-served after our 2020 entrants have registered. We will have a waitlist once the entrant list is full to improve runners’ chances of getting to run this beautiful ultra – our 25th Miwok.

Registration link for the 2021 Miwok 100K at Ultrasignup.com: Miwok 2021 Registration

Registration will be open for the 2020 entrants November 1 through November 7, 2020. (If you were on the 2020 entrant list, you must register by midnight on November 7th to be assured a spot.)

On November 8th, registration will open for everyone else. We do expect to have spots available.

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.


The 2021 entrant list will be posted here in November, 2020 as soon as all runners have registered.
