High-Altitude Swimrun in Colorado
ÖTILLÖ Colorado USA takes place in Fort Collins, featuring a course set at an elevation of more than 5,000 feet. The event is staged at Lory State Park and Horsetooth Reservoir, providing a landscape that transitions between open-water coves and rugged single-track trails. This location represents the only high-altitude race in the U.S. series.
Participants can choose from three distinct race distances:
- Colorado Experience: 9,656 m total (2,414 m swimming and 7,242 m running) with 89 m elevation gain.
- Colorado Sprint: 17,703 m total (4,828 m swimming and 12,874 m running) with 288 m elevation gain.
- Colorado World Series: 37,820 m total (8,045 m swimming and 29,773 m running) with 637 m elevation gain.
The event includes categories for male, female, and mixed teams, as well as solo categories for the World Series and Sprint distances. Mandatory equipment includes a wetsuit, shoes with grip, and a whistle. Solo racers are also required to use a flotation device.
The race venue is the Soldier Canyon Event Facility in Bellvue, approximately one hour north of Denver International Airport. On-site facilities include indoor restrooms at the start and finish area, and a bag drop for changing clothes. All finishers have access to food and drinks after reaching the finish line.
Packet pickup is held the day before the race at a local running store in Fort Collins, though a race-morning pickup option is available as a pre-purchased add-on. Visit the organization's website for the most recent information.
