Salt Flats Endurance Runs

The Salt Flats Endurance Runs take place at the Bonneville Salt Flats International Speedway near Wendover, Utah. This event offers multiple ultramarathon distances including 50K, 50 mile, 100K, and 100 mile races, all starting simultaneously on Friday morning. The courses begin on the iconic salt flats, featuring a mix of salt, mud flats, and scenic mountain "islands." Longer distances include rolling hills and significant climbs, with the 100-mile route crossing into Nevada. A new 5K and 10K fun run were added in 2026, ideal for families and crew members. The event finishes back at the salt flats, providing a unique endurance running experience in a striking natural setting. Visit the organization's website for the most recent information.
