63.5 miles through the Tushar Mountains of southern Utah. 16,085 feet of climbing. Never drops below 8,855 feet. Every aid station, every descent, every rest section happens above the elevation where most races reach their hardest climbing. One of the toughest 100Ks in North America.
100 miles from Memory Grove Park below the Utah State Capitol to North Salt Lake. 20,869 feet of gain. A 5,768 ft overnight climb to Francis Peak with no crew for 34 miles. The newest 100 on the Wasatch Front — and already one of the hardest.

100 miles point-to-point across the Wasatch Range. 26,000 feet of gain. A 4,400 ft wall in the first 7 miles. A high point at 10,462 ft that doesn't arrive until mile 72. The tightest cutoffs in Utah ultra running. Here's what the data says and how to race it.
100 miles with 26,000 feet of gain, averaging 8,700 feet the entire way. A high point at 12,272 feet on Mann's Peak. Temperature swings of 60+ degrees. The highest race in Utah — and one of the most underestimated. Here's what the data shows and how to race it.
101.78 miles. 21,600 feet of climbing. Two summit zones above 9,000 feet. A mandatory shuttle. No crew access for 40 miles. 2025 finishers called it harder than Bear and harder than Wasatch. Here's everything you need to know about the Goat Rattler 100.
