Uinta Wilderness Ultra

The Uinta Wilderness Ultra is a trail running event in the Uinta Mountains with two distance options. The course runs on mountain ridges, through pine stands, and past mountain lakes, and includes singletrack, ATV roads, and river crossings. The race starts and finishes at the North Slope Parking Lot off Mirror Lake Highway.

Distances

  • Half Marathon: 13.5 miles, 1,822 ft climbing, 5 hour cutoff.
  • Marathon / Ultra: 27 miles, 3,627 ft climbing, highest point listed at 9,448 ft, 8 hour cutoff.

The marked course includes a wooden bridge over the East Fork of the Bear River, Lily Lake, ridge sections with valley views, and aid stations located on the loop (examples at about mile 3.2 and mile 7.6 on the route). The marathon or ultra consists of running the 13 mile loop twice in opposite directions.

Aid stations at the finish and on course are stocked with water, ice, Tailwind electrolyte drink, fruit, candy, chips, Uncrustables, bug spray, sunscreen, and a first aid kit. Every finisher receives an award and all runners receive a T-shirt.

Race rules and logistics note that a National Forest day pass is required for all vehicles (fee required and must be displayed), each runner must carry at least a 16 ounce water bottle, dogs are not allowed on the course, animals must be leashed at the finish, and participants must follow Leave No Trace principles. Entry fees are non refundable; race deferral may be arranged with the organizer before August 19. The nearest town with lodging is Evanston, Wyoming, about 30 miles north, and multiple dispersed and maintained camping options are available near the start area.

Volunteer roles include course marking, aid station support, finish line duties, check in, and parking; volunteers receive a race shirt and entry incentives based on hours served. Visit the organization's website for the most recent information.
