Run up a slot-like red rock canyon, trek atop a packed natural clay fin under colorful hills, power up and speed down remote trails, and catch great vistas along ridgelines. There is a 50km ultra, a 25km, and a new 10km.
The race is located in Richfield, Utah, just a 2 hour 35 minute drive South of the SLC International Airport.
