Fort Collins, CO

Taking place on the trails and hills west of Fort Collins in Lory State Park and Horsetooth Mountain Park, the Quad Rock 25/50 will take you on a tour of the Fort Collins skyline, situated on the northeastern edges of Colorado’s mighty Rocky Mountains. Look east from the course’s high ridges and you’ll see the Great Plains extending into Nebraska as afar as the eye can see. Look west and you’ll take in the layered ridge lines and summits of Northern Colorado’s Rocky Mountain swell, dominated 30 miles away by a towering Longs Peak, the undisputed monarch of Colorado’s northern Front Range.
