What Makes It Great

The shortest Bighorn event starts at Dry Fork Ridge and follows the final 18 miles of the 100-mile course to the finish at Scott Park. Runners crest Camp Creek Ridge at 8,100 feet, descend through Sheep Creek drainage and Tongue River Canyon, and finish on gravel roads into Dayton. A great introduction to Bighorn's rugged terrain and canyon scenery without the ultra distance commitment.
