COVID-19 Updates

7/7/20 COVID-19 update

The modified permit has been approved. This means 100-Miler only, limit 35 runners, staggered starts every 15-seconds, enhanced safety and COVID mitigation plan in effect. Registration is closed. Runners check your email.

6/18/20 COVID-19 update

We’re moving forward at full force to put on Cool Moon despite uncertainties of COVID. As it stands now, all events are canceled in the Auburn State Recreation Area through June 27th with no direction thereafter. For the 100-Miler, we have 14 athletes in the race and 11 on the Waitlist. If permitting or grouping restrictions even limit events to 25 people, we will still put forth the race. As soon as I get more assurance from the State, I’ll let the 11 runners on the Waitlist in, then I may open registration (to more runners)... OR close/cap the registration at 25 runners.

4/29/20 COVID-19 update

I’m pausing registration until further notice. This means you may still register for Cool Moon, but the pause acts like a Waitlist. Your credit card will not be charged at this time. Auburn State Recreation Area has cancelled all special events through June 7th. This may be extended. Cool Moon is a resilient race, so I intend to put it on as long as it follows the State and ethical guidelines. If the race is unable to occur, your registration will be rolled over to the 2021 event or you will have the possibility for a partial refund 75%-50% relying on if we move forward paying third parties for the event costs in early June.


The 100-miler starts at 5:00am on Saturday, August 8th, 2020.

The course consists of a 13.5-mile loop and an 11.5-mile loop, upon which runners will alternate. Each runner will complete (4) 13.5-mile loops and (4) 11.5-mile loops to achieve the 100-mile distance. Runners will start North on a 13.5-mile, counter-clockwise loop from Cool Firehouse, head west to Pig Farm and Salt Creek, south toward the American River and back into Cool. Next, they will follow an 11.5-mile loop from Cool Firehouse South toward Northside School, to Knickerbocker, to the Rim Trail, past the radio towers, back to Northside School and Knickerbocker, and back to Cool. This course is not easy, do not take it lightly.

The course consists of single track and fire roads.

13.5-mile Loop elevation approximately 2200′
11.5-mile Loop elevation approximately 1150′
