Participant requirements and logistics
Each entrant must complete eight hours of volunteer service prior to July 1 or pay a $100 opt-out donation to the Ouray Trail Group. Entrants who have not submitted the service form or paid the opt-out fee by July 10 will forfeit their registration fee and be denied entry. The race is no longer processed as a UTMB qualifier.
Runners are required to carry a provided SPOT tracker for live tracking, with location updates every five minutes. Top finishers in the 100 mile event are eligible for cash awards: $1,000 for the top male and $1,250 for the top female, contingent on urine and/or blood drug testing. Tests may include checks for steroids, testosterone, EPO, and THC; a THC threshold of 150 ng/ml is noted for a positive result. Visit the organization's website for the most recent information.
