Runners follow an out-and-back course that runs through Valley of Fire State Park near Lake Mead for the half marathon, which starts with the other races at the visitor center parking lot on Valley of Fire Highway. From there, the 13.1-mile course heads along the road north toward White Domes, with a brief out-and-back detour at the mile 2 marker. After that, the course heads north again all the way to the second turnaround point between miles 7 and 8, and then heads south back to the visitor center for the race finish.
