Tooele Trail Racing puts on 4 or 5 great, minimalist trail runs each year.  No shirts, no medals, just come for the love of the trail.

The 2023 Crimson Canyons Ultra includes a brand new 50 mile route, in addition to our traditional 50km, 25km & 10km trail runs.  All will be run on Saturday, September 16, 2023.  The new 50 mile route will climb to the summit of White Pine Peak at 10,200 feet and then drop 4650 feet over 18 miles on the newly completed Spinal Tap Trail - this is the signature center of the 50 miler.

No matter the distance run, pristine red rock canyons and primal trails await! This race links several canyons, dry washes, remote sections of the Paiute ATV Trail system, and the brand new Pahvant Mountain Bike Trail System, into a 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.

The race is located in Richfield, Utah, just a 2 hour 35 minute drive South of the SLC International Airport.
