About this race
Chase the Moon is a 12-hour solo ultramarathon and team relay, run overnight under the light of the full moon on the flowing and fun Highlands Ranch Backcountry singletrack trail system (we promise some incredible nighttime views of the metro area and front range). Running from sunset to sunrise means cooler temps and the opportunity to see how many miles you can accumulate in 12 hours. Solo runners who complete 100K will earn a coveted glow-in-dark buckle!
