The Mormon Trail is the 1,300-mile (2,100 km) long route from Illinois to Utah that members of The Church of Jesus Christ of Latter-day Saints traveled for 3 months. Today, the Mormon Trail is a part of the United States National Trails System, known as the Mormon Pioneer National Historic Trail.

The HURL links up the 13 major peaks surrounding the Hyalite Creek drainage while staying on the ridge whenever possible. The route consists of 14 off-trail miles accompanied by 7.5 miles on singletrack and 2.5 miles on road. There is somewhere in the neighborhood of 13,000-14,000 ft of elevation gain on route with very little time on flat ground. Most of the terrain is Class 2/3 with Class 4 moves on loose rock sprinkled in.
