Come join us for the highest DOWNHILL half marathon in the country and possibly the highest DOWNHILL 4 Mile Run!

Do not be misled by the name but this is the Slacker Half Marathon/4M Race! It is the highest downhill half marathon in the country–beginning at 10,630 feet and traveling over a rolling hill descent to 8400 feet! The half marathon begins at Loveland Ski Area--BASIN and travels the first mile on dirt roads before joining a non-motorized paved bike path for five miles through a Forest Service area of wetlands and natural waterfalls on a trail built to sustain the weight of an ambulance!
