Ötillö Swimrun Colorado 2026

If you’re looking for an adventure that smells of nature and the wide-open spaces of Colorado, the Ötillö SwimRun Colorado in Bellvue ticks every box—even the ones you didn’t plan for 🏔️.

Pick your format based on what you’re craving that day: Colorado Sprint to go full speed and treat yourself, Colorado Experience to savor the terrain and scenery, or Colorado World Series if you want the big thrill and the “I’ll remember this for a long time” option 🏅.

Come for the race, stay for what’s after—because around Bellvue you’ve got plenty of ways to reward yourself without going miles out of your way ✅.

After you finish, head over to Horsetooth Reservoir for a stroll along the water, or gain some elevation at Horsetooth Rock for a view that settles it for everyone.

If you want to stay close by, swing through Fort Collins: a pleasant old town, terraces, and the perfect stop to relive the race “turn by turn” over a great meal.

In short, you come to swim and run between the lakes, and you leave with your head full of images—and a little urge to do it all again.
