About This Race

The 25K serves as an ideal middle-distance option, perfect for runners seeking a solid challenge without ultra-distance commitment. This distance allows participants to experience the technical aspects of the terrain while maintaining a faster pace throughout. The course length makes it accessible to intermediate trail runners looking to test themselves on demanding Colorado trails.

The courses wind through Black River State Forest's diverse terrain, shaped by Ice Age glaciation into the buttes, hills, and ridges that characterize this landscape. Scenic overlooks punctuate the trails as they traverse woodlands and rolling terrain, with the ridge sections offering the most dramatic views across the forest canopy.

The 85K distance uniquely combines all race courses into one comprehensive tour of the forest, starting and finishing at the Smrekar Lot. Runners experience the full range of terrain and elevation changes, from gentle woodland sections to the more challenging ridge climbs that provide those coveted overlook rewards.
