Ouray 50 Mile Endurance Run

Ouray 50 Mile Endurance Run

The Ouray 50 Mile Endurance Run is a 50 mile mountain ultramarathon held in Ouray, Colorado, with the start and finish at Fellin Park. The course features substantial climbing with a listed elevation gain of 23,582 feet and an average elevation described as nearly two miles above sea level. The organizer is Ouray Ultras.

The route includes highly technical trail sections and terrain intended to be more demanding than a typical 50 mile event. Runners are required to carry a provided SPOT tracker during the race; locations will be updated every five minutes. The race uses a 24 hour cutoff for official finishes.

Entry and participant requirements include a mandatory service obligation of eight hours of volunteer trail work or volunteering at another trail ultramarathon to be completed before August 15. Participants may opt out of this service requirement by making a $100 donation to Ouray Trail Group. Entrants who have not submitted the service form or paid the opt-out fee by August 22 will forfeit their registration fee and will not be permitted to participate.

The event provides cash awards for top 50 mile finishers with drug testing administered to winners. Cash awards are $500 for the top male 50 mile finisher and $625 for the top female 50 mile finisher. Podium awards are described as laser cut from traffic cones and a genuine western buckle is among the finisher items. The event is no longer a UTMB qualifier beginning in 2022.
