About This Race
The 85K distance represents the marquee challenge, demanding both physical endurance and mental fortitude over its extended loop format. This ultra-distance option attracts seasoned trail runners ready to test themselves against sustained technical terrain and significant time on feet. The course's demanding nature makes it a proving ground for runners seeking to push their limits in Colorado's rugged landscape.
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.
