The 2021 Crimson Canyons Ultra was held Saturday, September 18, 2021.
It was our 5th official year. Mother nature again threw a chaotic storm our way on race day, but that added to the adventure.
Explore wild red rock canyons and primal trails in this unforgettable run. This run links several canyons, dry washes, remote sections of the Paiute ATV Trail system, and the brand new Pahvant Mountain Bike Trail System, into a very unique experience. 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.
