Point-to-point from East Mountain Wilderness Park (near Kaysville) to the Soldier Hollow pavilion (Midway) along the crest of the central Wasatch Mountains, crossing Bair Canyon, Francis Peak, Farmington Flats, Big Mountain, Lamb's Canyon, Mill Creek Canyon, Desolation Lake, the Wasatch Crest, Brighton, Catherine and Sunset Passes, American Fork Canyon, Pole Line Pass, Baker Pass and Decker Canyon. Altitude ranges 4,887 to 10,462 ft. Daytime aid stations stock water, electrolyte drink, fruit, a salty item and usually soda; nighttime stations add hot drinks; 'crossover' stations carry all of the above; most stations also add soup, potatoes, sandwiches, sweets, pasta or breakfast items depending on volunteers. Desolation Lake and Rock Springs have no vehicle access and are hike-in stations supplied only with water, electrolyte drink and limited other items. The finish-line aid station serves pancakes, bacon, eggs, coffee, tea, broth, fruit, chocolate milk and (later) grilled cheese, plus at least 3 independent food trucks. The race caps entries at an approximate range of 280-330 starters a year for trail-access reasons; there is no single published fixed field cap.
A 100-mile point-to-point trail run across the central Wasatch Mountains, from East Mountain Wilderness Park near Kaysville, Utah to the Soldier Hollow pavilion in Wasatch Mountain State Park, Midway, Utah. Starts 5:00 a.m. the first Friday after Labor Day with a 36-hour limit (finish by 5:00 p.m. Saturday). Approximately 24,000 ft of cumulative gain and 23,300 ft of loss, altitude 4,887 to 10,462 ft. Entries are capped by trail-access limits to an approximate range of 280-330 starters a year (no single published fixed number). One of the five oldest 100-mile trail runs in the country and the mandatory closing race of the Grand Slam of Ultrarunning, which it organizes and awards.
First run in 1980; two of five starters finished that first year. The idea for the Grand Slam of Ultrarunning (Western States, Vermont, Old Dominion and Leadville, run within the same summer, with Wasatch as the mandatory closing race) was proposed by Fred Pilon of Ultrarunning Magazine in 1985 and organized in cooperation with then-Wasatch race director Steve Baugh; the first Grand Slam award was given to Tom Green in 1986. By 2021, 165 of 298 starters finished. The race's official written history (by Dana Miller, a 20-time finisher since 1985) is a multi-year article series published on the site's own History page.

This changes nothing on the page on its own. Somebody checks it against the race first.
We want the address of the file the race publishes, not the file. We download it from there so the page can say where the line came from.
We read every one of these and we write back. Every fact here carries the source it came from, and the way a wrong one gets fixed is a person checking it against what you tell us.
NavRun builds your pacing from your own training, then turns it into a plan your crew can follow: when to leave and where to park.
