Behind the Rocks Ultra starts and finishes at the Behind the Rocks Trail, along the border of the Behind the Rocks Wilderness Study Area.

The bike course is physically demanding but technically mellow all on double track and gravel bike compatible. There are steep ups and downs with only a few rocky bits, no drops or steps. The run is typical North desert with ups and downs.

Point to point scenic trail run follows the Tabeguache Trail from Bangs Canyon trail head to Unaweep Canyon for a net descent but with a significant climb. Self-supported, double track but rough.

Scenic singletrack loop on top of Grand Mesa mostly through forest and meadows with a long crest section that is narrow with short sections of exposure. Starts at 10,455' with a high point of 11,170'.

Above Colorado National Monument and Glade Park on Pinon Mesa in the Fruita section of the Grand Mesa National Forest. Run through aspen groves, lush meadows, pine forest and often a mud hole or two. Wildflowers are usually abundant.
