Salt Flats Endurance Runs

Salt Flats Endurance Runs is a desert ultramarathon in Wendover, Utah, anchored at the Bonneville Salt Flats International Speedway. Runners choose from 100 mile, 100K, 50 mile, 50K distances, plus a 5K fun run and a 10K. The courses traverse the salt flats—the same stretch where land-speed records are set—before meeting the ‘Islands,’ peaks rising from a white sea.

The 50K offers a mid-race turnaround, while 50 mile, 100K, and 100 mile routes feature rolling hills and significant climbs; the 100 miler even crosses into Nevada. All races finish back at the start; organizers promise electrolyte-rich celebrations and finishers awards. Visit the organization's website for the most recent information.
