Yellow Fork singletrack and canyon ridges in the Wasatch foothills
Other trail races within 163 miles
A demanding 50K that takes in the best of Yellow Fork Canyon and the Butterfield trail network. The opening 11 miles are the crux — a long, gnarly push over rocky ridges and through scenic canyon terrain before dropping into Yellow Fork. From there, the Red and Blue loops deliver some of the most scenic trail running in the Wasatch foothills, with the course closing on exposed singletrack back to the Butterfield Trailhead. No pacers; drop bags available at Yellow Fork.
