Quad Rock 25 & 50 Mile Trail Races

Event Overview

Taking place on the trails and hills west of Fort Collins in Lory State Park and Horsetooth Mountain Park, the Quad Rock loop will take you on a tour of the Fort Collins skyline. Look east from the high ridges and see the Great Plains, look west and witness the layered ridgelines and summits of Northern Colorado’s Rocky Mountain swell, dominated by a towering Longs Peak.

Participants will tackle a 25-mile loop with approximately 5,500 vertical feet ascended. The 50-mile challenge includes running the second loop in reverse, resulting in a net vertical gain exceeding 11,000 feet.
