Salt Flats Endurance Runs

Salt Flats Endurance Runs take place at Wendover, Utah, on April 30 and May 1, 2027, out on the state's salt desert. The ultra distances all start at 7:00 a.m. on May 1: 100 miles, 100K (62 miles), 50 miles and 50K (31 miles). A 10K and a 5K complete the program. The routes cross vast, flat, blindingly white expanses that offer almost no visual landmarks and a real sense of isolation.

That emptiness is the difficulty here as much as the mileage: the ground is flat, but running for hours with nothing to measure your progress against is mentally demanding, and desert conditions can turn extreme. The long formats are for runners already experienced in ultras, with a year of build behind them, a written fueling plan and sun protection worked out in advance.
