We have plenty of spots left for 2021.

2015, 2016, 2017 and 2020 we sold out but had a waiting list. We are not there yet for 2021 - we still have plenty of spots left. The Uncomphagre National Forest Service is allowing 250 spots this year and as we are inscribed as a UCI XCM event, 30 of those spots will be held for 100 Mile Elite/Open athletes until June 1st. After June 1st, we will open those remaining 30 spots to all on the waiting list.

Once the race is full, how does the waiting list work?

1) Any spots given up will go to racers on the waiting list on a first come/first serve basis.

2) We assume that if you are on the waiting list you would like a spot so if by chance you change your mind please remove yourself.

3) For the years that we sold out enough spots opened up and 90% of those on the wait list had an opportunity to race if they wanted to, so don't hesitate to sign up, your chances are favorable.

Colorado Search & Rescue Card is REQUIRED for all race participants!

San Miguel County Search & Rescue has asked that all racers have a Colorado S&R card. It is $3 for one year OR $12 for 5 years and has tons of great benefits. You can purchase yours online today:
