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 30K sits in the middle ground between an introduction and a genuine challenge. It covers more of the course's signature terrain - Navajo sandstone formations, technical singletrack, and desert washes - while remaining accessible enough for runners who aren't yet ready for a 50K or 50-miler. It's considered a proper intro to what makes this area of Moab unique: the remoteness, the rock, and the views toward the La Sal Mountains.
