What Makes It Great

Behind the Rocks Ultra starts and finishes at the Behind the Rocks Trail, along the border of the Behind the Rocks Wilderness Study Area. Moab's last hidden gem; its tall standing Navajo Sandstone domes and fins can be seen from many places along the course. This course traverses some remote trails, and gives you the opportunity to enjoy the desert solitude. From smooth double track to sandy washes, technical doubletrack, and challenging singletrack, Behind the Rocks Ultra will test you mentally and physically.

The 50K gains around 3,100 feet of elevation and runs through three aid stations with a 12-hour cutoff. It offers a more complete experience of the Behind the Rocks Wilderness - covering technical slickrock, rim running with arch views, and sandy desert stretches - while being slightly more forgiving than the flagship 50-miler in terms of total vert and distance.
