The Black Squirrel Trail Half Marathon takes place on the trails of Lory State Park northwest of Fort Collins, Colorado. The course makes a perimeter loop of the park and offers views to the east of Horsetooth Reservoir, Fort Collins and the Great Plains, and to the west of the Rocky Mountain peaks.
