Course Description

The course essentially consists of two big loops: first counter-clockwise around Flying Dog, then across to Jeremy Ranch for a second loop up the Mormon Pioneer and Great Western trails.

Twisted Fork Ultra elevation profile The race begins with a short sprint to the single track. Other than a bit of dirt road running 90% of the course is on single track itself. But don’t worry, you’ll have plenty of opportunity to pass other runners. You’ll run what is called the “Flying Dog” loop counter-clockwise. This will give us a short climb at the beginning, then take you down to a flat section before the big climb up to the top of Flying Dog. We will have a timing mat at the bottom and top of this climb and the combined time for the Flying Dog climb and the Big Mountain Pass climb (later in the race) will determine the King and Queen of the Mountain.

Next there is a long, fast descent through aspen groves and past a beaver dam as you make your way through the woods and down to the 24/7 trail intersection, where you turn right and continue down to Jeremy Ranch. After the Jeremy Ranch aid station you start a 19 mile loop that will bring you back to this point. The course turns down a dirt road for 4 miles to the Mormon Flat aid station. This entire section is easily accessed by family and friends. Once you reach Mormon Flat you turn off the dirt road to climb up to Big Mountain Pass on the Mormon Pioneer Trail. This historic trail was once a busy route that was used by many of the earliest settlers of the American West, famously the Donner-Reed party and subsequently the Mormon Pioneers. This is the second of our two climbs that define the King and Queen of the Mountain and there will be timing mats at the bottom and top (as for the Flying Dog climb).

Once you reach Big Mountain pass you will turn left onto the Great Western Trail, following the route of the Wasatch Front 100 course. But when you reach Pence Point (where the Wasatch course turns and descends into Alexander Basin) you will keep going straight and continue past the cell towers above Jeremy Ranch. From here it’s a beautiful two mile descent via Moose Hollow back down to the Jeremy Ranch aid station where your family and friends will see you again.

At this point you’re about 80% done: just seven miles to go! You have a short steep climb retracing your steps back up the 24/7 trail, then fast gently rolling terrain traversing above Jeremy Ranch, across Red Hawk, above Bob’s Basin and then finally descending on the Stealth trail to the Spring Creek trailhead at the bottom of Glenwild.


Finally, a quarter-mile of pavement takes you to the finish: duck under I-80 via a pedestrian tunnel, and along the path to the finish line at Newpark Amphitheater, where you’ll be greeted with live music, food and drink.An award ceremony will follow the race and recognize the top three overall male and female, as well as age categories category winners by gender. Awards will also be given for the King and Queen of the Mountain as well as the male and female Sprint Champions. Bonus awards will be announced during the ceremony.
