[UPDATE 9-July-2020: We are planning for our race to be held on the scheduled date this fall in September!  But given continued global uncertainty, we have changed our registration to WAITLIST only, so that no one will be charged until one month before the race date.  Stay say everyone, and enjoy the outdoors and trails as much as possible!]

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 systems, and the brand new (2019) 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 will be a 25km (approximately 16 miles) and a 50km ultra (approximate 31 miles). 

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

Race date is Saturday, September 26th, 2020.

The new Pahvant MTB Trail System completed the first 20 of 100 miles of single track in 2019.  Both distances will catch several amazing new single-track mountain bike sections that parallel previous years course routing. So expect to hit a couple of great new single track trail sections.

Note, because of licensing with the Forest Service we will not be holding a 50 miler in 2020.  But with tons of great new single track being created in 2020, we hope to bring it back online..
