Chase The Moon

Chase the Moon is a 12-hour team relay and solo ultramarathon, run overnight under the light of the full moon in the Highlands Ranch Backcountry trail system (we promise some of the best views of the metro and front range). Run as a solo ultrarunner, or get your fellow moon chasing friends for a 3-person or 5-person relay team.

NEW THIS YEAR! Want a taste of insomniac running, but not sure you want the full 12 hours? That's OK, we now offer shorter and set distances including 5 mile, 10 mile, 25K & 50K. So pick your event, grab your headlamp, and let's rock some incredible nighttime singletrack!

Chase the Moon begins at 7 p.m. on Friday during a beautiful Rocky Mountain sunset, continues through the night beneath the illumination of the full moon, and finishes at 7 a.m. on Saturday as the sun rises in the east to paint the foothills with alpenglow. Don’t miss this unique and incredible running experience. A portion of the proceeds of the race benefit the open spaces and trails of Highlands Ranch, and our partner charities.
