Black Squirrel Half Marathon Fort Collins, CO   Sep 12, 2026

The Black Squirrel Half Marathon will take place on the wonderful trails of Lory State Park to the northeast of Fort Collins, Colorado.

The half marathon course offers a tour of the outer boundaries of Lory State Park, providing breathtaking views to the south and east of Horsetooth Reservoir, Fort Collins and the Great Plains; and to the West of the awe-inspiring Rocky Mountain swell.

The race covers a variety of terrain, all of which is runnable although technical in places. After a mile of dirt roads, the course ascends a little under four miles and 1,500 feet to the apex at 7,000 feet on Lory’s west ridge. The views are well worth the climb. A bomber descent follows, leaving three and a half miles of beautiful, gently rolling hardpacked singletrack into the finish.

The aim is to offer a trail running experience that is challenging, yet accessible to all.
