Utah Trail Races & Ultramarathons
Utah has nearly a dozen trail races and ultramarathons on the calendar, and two-thirds of them are in Moab alone — red-rock, slickrock desert terrain around 4,000 feet. The outlier is Speedgoat Mountain Races at Snowbird, widely called the toughest 50K in the U.S., climbing to 11,000 feet at Hidden Peak. Season runs October through July depending on elevation.
Masters Athlete Insights
Two-thirds of Utah's calendar is one race, in one place, on one kind of terrain: Moab's red-rock slickrock and sand, at a moderate ~4,000 feet where heat and technical footing are the limiters, not altitude. Speedgoat is the exception that changes the whole training picture — 11,000 feet of alpine terrain where the climbing itself, not the distance, is the race. Figure out which Utah you're training for before you build the plan.
For a Moab-distance goal, our 16-week 50K plan is a reasonable base; for something Speedgoat-adjacent, prioritize hill repeats and altitude exposure well beyond what that plan assumes on its own.
FAQ
What is the best Utah trail race for beginners?
The Arches Half Marathon near Moab — a defined 13.1-mile distance on scenic but non-technical red-rock terrain, a good introduction to desert racing before a longer Moab ultra.
What is the hardest trail race in Utah?
Speedgoat Mountain Races at Snowbird — widely called the toughest 50K in the U.S., with over 11,000 feet of climbing to an 11,000-foot high point in just 31 miles.
Why are so many Utah trail races in Moab?
Moab's slickrock and sandstone canyon terrain is some of the most distinctive trail-running ground in the country, and it draws race organizers accordingly — six of the nine races on this page are there.
When is trail racing season in Utah?
Roughly October through July. Moab's desert races run fall through spring to avoid summer heat; Speedgoat, at altitude, runs in July once the high country is clear of snow.
Are there masters (40+) divisions at Utah trail races?
Most races on this list award age-group results in 5- or 10-year brackets rather than one "masters" category, but brackets vary by organizer — check each race's rules page before registering if it matters to you.
