Need to Know

Mad Moose Events' Special Request:
While running on the Hunter Canyon Rim Trail, please be aware of where you step so that you are sure to stay off of the Cryptobiotic Crust. The crust is a living organism that takes a long time to recover from human disturbances.


Behind the Rocks 50 miler will be held at the end of March. The course was designed to highlight the technical slickrock trails of Moab, the views of the Behind the Rocks Wilderness area, and the snow capped La Sal mountains.

The race will start at the 24-Hours of Moab and head north for a mile and a half to the Behind the Rocks Trail. For 10 miles, continue south on the trail to the Hunter Canyon Rim trail. Turn left onto the Rim Trail for 4.5 miles until Kane Creek Road. The rim trail starts off as a doubletrack but becomes a singletrack as you get closer to the canyon. As you get to the bottom, the trail also becomes super technical and somewhat difficult to follow. There are a few steep ledge sections that will require to you climb down.

Once you are off of the rim, turn right at Kane Creek road and head south for a mile until you reach the Amasa Back Trail. Turn left onto Amasa Back and immediately turn left onto HyMasa Trail. You'll follow HyMasa for less than a third of a mile until you intersect back with the Amasa Back trail. Once on Amasa Back, continue for a half mile until you turn right back on the the singletrack of HyMasa. Follow Hymasa for the next few miles, it will cross the Amasa Back a few times, until you reach Captain Ahab Trail.

Turn right at Capt Ahab and follow it for less than a quarter of a mile until you reach Amasa Back, then turn left. Run on Amasa Back until you reach the aid station in less than a mile. After the aid station turn left and drop down into Jackson Hole. Jacobs Ladder is right after the aid station. Just as it sounds, its a ladder down from the rim, be ready for a tough half-mile on the way back!

Run Jackson Hole counter clockwise for 4 miles and then back up Jacksons Ladder. Take a minute to enjoy the views of the Behind the Rocks with the snow covered La Sal mountains behind at the top of the ladder. Once you come back to the aid station, turn right back onto Amasa Back. Follow Amasa until you reach Rockstacker, a singletrack trail. Turn right onto Rockstacker and follow it until you reach Jacksons Trail. Turn left on Jacksons Trail.

Once you reach the parking lot, turn right onto Kane Creek Rd and follow the Rd until you are back at the Gatherer Canyon aid station. Turn left back onto the Rim trail for 4.5 miles until you reach Behind the Rocks intersection. Again turn right, not left like the way you started, and head back on the Kane Creek trail for 11.5 miles to the finish.
