Sky Pilots Ouray Backyard Ultra

The Sky Pilots Ouray Backyard Ultra is a unique endurance running event held in Ouray, Colorado, starting at Fellin Park. Participants run a 4.167-mile out-and-back course featuring a mix of asphalt track, smooth dirt roads, and the scenic Uncompahgre River Walk with minimal elevation gain (140 feet). Runners must complete each loop within an hour to continue, with the race lasting until only one runner remains, who must then complete one additional lap to win.

The course sits at about 7,700 feet altitude, adding a challenging element despite its easy terrain. Amenities include personal stations, nearby hot springs, and local shops, creating a supportive and vibrant atmosphere. Visit the organization's website for the most recent information.
