Sky Pilots Ouray Backyard Ultra

The Sky Pilots Ouray Backyard Ultra is a unique running event held in Ouray, Colorado, featuring a "last person standing" format. Participants complete a 4.167-mile course, and if they finish within an hour, they continue to run each hour until only one runner remains. The course is relatively easy, with minimal elevation gain, but the high altitude of 7,700 feet may pose a challenge.

Runners have designated personal stations for support, and the event encourages a festive atmosphere with jeerleading and nearby amenities, including hot springs and local shops. Registration closes shortly before the event. Visit the organization's website for the most recent information.
