Overview

The Black Squirrel Trail Half Marathon takes place on the wonderful trails of Lory State Park to the northwest of Fort Collins, CO.

The trail half marathon course offers a tour of the outer boundaries of Lory State Park, providing breathtaking views to the 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, with a mix of moderately technical and non-technical trails. After a mile of dirt roads, the trail ascends a little under four miles and 1,500 feet to the apex of the course at 7,000 feet on Lory’s west ridge. The views are well worth the climb. A rapid and somewhat technical descent follows, leaving three and a half miles of beautiful, gently rolling hardpacked singletrack into the finish. Finishers can start chowing down at the post-race pancake breakfast and kick back and enjoy the post-race party.

We will also have a fun and free kids trail race on a 1 mile loop beginning and ending from the start/finish area of the main race.

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

Course Description

The Black Squirrel Trail Half Marathon will start and finish at the Soldier Canyon Picnic Area in Lory State Park to the northwest of Fort Collins, Colorado. Runners will head south on the Lodgepole Drive Spur Road for a little less than a half mile before looping back north on the main Lory Service Road to the Timber Trailhead where they will access the Timber Trail and ascend all the way to the Westridge Trail.

The course takes a right on Westridge, looping around to connect with the Howard Trail (right turn), which runners will take down to the Arthur’s Rock Link Trail (hard left) and Arthur’s Rock Trail (right) to the Arthur’s Rock Trailhead. From the trailhead/aid station, the course will run south on the west side of the South Valley Trail until it turns back north on the east side of the loop at the Horsetooth Mountain Park border. Runners will then pass through the Arthur’s Rock Trailhead again to connect with the East Valley Trail which will take them back to the finish.

You will climb ~1,500 feet between mile two and mile six, descend an equal distance over the next two and a half miles and then run on gently rolling terrain for the last 4.5 miles.
