Chase the Moon

Chase the Moon is an overnight endurance event held on June 27, 2026, at Mountain Vista High School in Highlands Ranch, Colorado. The event uses a rolling 10.3 miles loop in the Highlands Ranch Backcountry Wilderness area that is almost entirely dirt trail with approximately 870 feet of elevation gain per lap and largely exposed views of the surrounding metro area and front range.

Event formats include solo and team relay options:

• 12 hour solo, 6 hour solo, 3 hour solo
• 50K solo
• 3 person relay
• 5 person relay with alternating shorter and longer loops

The course is well marked with flags, reflective tape, signs, and spray chalk. Runners are required to carry a headlamp or handheld light source while on course. Two aid stations support runners: Outlaw Aid Station at about mile 4.3 and the Start/Finish at about mile 10.3; both offer water, Tailwind endurance fuel, soda, and a selection of sweet and salty snacks plus fruit. Port o potties and basic first aid supplies are available at aid stations.

Crew support and drop bags are allowed only in the designated Start/Finish area. Pacers are not allowed. Race medical staff are based at the Start/Finish and serious evacuations are reserved for critical medical needs. Distances may vary slightly each year due to permitting.
