Other trail races within 50 miles
Quad Rock 25 Mile covers a single clockwise loop through Lory State Park and Horsetooth Mountain Park, gaining 5,500 feet across 25 miles of mostly singletrack trail. The course winds through exposed ridgelines with the Great Plains to the east and Longs Peak to the west, connecting some of the most beloved trails in the Fort Collins trail running scene. A well-organized, festive event with a full post-race meal at the Soldier Canyon finish.
