Event Overview

A 100-mile point-to-point crossing of Utah's Wasatch Range with roughly 24,000 ft of climbing, high mountain terrain, and a 36-hour limit.

Course & Terrain

Point-to-point mountain course from East Mountain Wilderness Park in Kaysville to Soldier Hollow.

Key course features to know before comparing this race:

• High point near 10,450 ft at Point Supreme, mile 72.3
• Wasatch Range traverse ending at Soldier Hollow
• Nearly 4,200 ft of climbing in the first 4.4 miles up Bair Canyon
• Desolation Lake and the Wasatch Crest Trail
• Catherine Pass and the Plunge below Mill Creek Peak
• High point near 10,450 ft

A sustained high-country trail route with long climbs and descents, at elevations that make pacing and weather preparation central. It starts at 4,887 ft in Kaysville and climbs nearly 4,200 ft in the first 4.4 miles up Bair Canyon to the Wasatch crest. It then follows the ridgeline south past Francis Peak, along Sessions Ridge and over City Creek Pass, Big Mountain Pass and Bald Mountain to Lamb’s Canyon. The second half climbs past Desolation Lake onto the Wasatch Crest Trail and over Catherine Pass (10,233 ft) to Point Supreme, the 10,462-ft high point at mile 72.3. Runners then go around Mill Creek Peak through the Glide and the Plunge and drop through Decker Canyon to Soldier Hollow at 5,541 ft. The organizer describes footpaths, game trails and dirt roads with stretches of sagebrush, scree, waist-high grass and fist-sized cobblestones. Some sections between aid stations exceed nine miles. Ribbons mark the course every quarter mile by day, and reflectors alternate with ribbons every eighth of a mile at night.

The organizer says race temperatures have typically ranged from 25 to 90°F. Many years bring mild running weather, but one year fresh snow fell on Catherine Pass with a wind chill below zero, another had trail temperatures above 100°F, and another was rainy and muddy on both days with low cloud limiting visibility. Utah’s low humidity can lead to severe dehydration, and the organizer expects entrants to know the signs of heat exhaustion, hypothermia, frostbite and altitude sickness.

Format & Support (as run)

Why This Race Matters

Wasatch is the third-oldest 100-miler in the United States, after Western States and Old Dominion. Richard Barnum-Reece conceived it in the summer of 1980, and Steve Baugh mapped the route. On September 27, 1980, five runners left Highway 89 near Winder Dairy for Sundance, and only Laurie Staton and Greg Rollins finished, together, in 35:01:21. The race has run every year since except 2020, when COVID-19 cancelled it, and John Grobben has directed it since 1988. Wasatch also created the Grand Slam of Ultrarunning, an idea from UltraRunning’s Fred Pilon in 1985, first awarded to Tom Green in 1986 and still run by the race. Wasatch is the mandatory final race of the Slam. Geoff Roes (18:30:55, 2009) and Bethany Lewis (22:21:47, 2014) hold the fastest times.

Preparing for a Race Like Wasatch Front 100 Mile Endurance Run

The 100-mile race guide covers the format as a whole. These guides go deeper:

• Walking strategy for ultramarathons: When and how to walk by terrain, effort and cutoffs.
• Crew and aid-station strategy: Crew tables, aid stops, drop bags and runner preferences.
• Gut training for ultrarunners: A six-week practice sequence for race-day fueling.
• Tapering for ultramarathons: Plan the taper and race week around your own recovery.

Best Fit

• Experienced mountain 100 runners who can look after themselves on long, remote stretches
• Grand Slam of Ultrarunning hopefuls, for whom Wasatch is the mandatory final race
• Runners who value tradition and trail stewardship over race-day spectacle
• Runners 60 and over, who may have a pacer from the start

Planning Notes

• Treat intermediate cutoff gates as part of the course. Build enough margin for aid stops and late-race slowdown, and verify every current gate in the official rules.
• Train for terrain-specific fatigue. Technical trails and mountain courses demand downhill durability, hiking efficiency, and reliable night lighting.
• The directory does not mark this as having simpler logistics. Confirm qualification, terrain, support, registration, medical, and withdrawal requirements before planning around it.
