ÖTILLÖ Colorado USA

ÖTILLÖ Colorado USA is a swimrun event in Fort Collins that combines open-water swims in Horsetooth Reservoir with trail running through Lory State Park at over 5,000 feet elevation. The course uses rugged single-track trails and open-water coves, with multiple swim-run transitions and notable elevation sections.

Three race distances are offered, each listing total, swim, run, and elevation:

  • Colorado World Series: Total 22.7 mi; Swim 5 mi; Run 17.64 mi; Elevation 1,986 ft

Logistics include a packet pickup location in Fort Collins the day before the race, limited parking at the Soldier Canyon Event Facility, and athlete parking and access arrangements within Lory State Park. Mandatory race gear is listed; event-provided items include color-coded swim caps, race bibs, and foldable cups. Athletes must supply wetsuits, a whistle, a compression bandage, and a tether or tow line. Water stops provide plain and electrolyte-infused water plus gels, and course littering can lead to disqualification. Awards are given to top solo and team finishers across categories. Volunteer positions are available and include a shirt and post-shift meal. Visit the organization's website for the most recent information.
