2015, 2016, 2017 and 2020 we sold out but had a waiting list. The Uncomphagre National Forest Service is allowing 300 spots this year.

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 from the waitlist.

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:
