Salt Flats Endurance Runs

At the Salt Flats Endurance Runs, you have a choice of 50K, 50 mile and 100 mile distances, with all three events starting at the same time at 7AM on Friday, and the finish cutoff for the 50K at 3pm Friday afternoon, the 50 mile at 9PM Friday evening, and the 100 at 7PM Saturday evening. This gives an 8 hr duration for the 50K, a 14 hr duration to the 50 miler, and a 36 hr cutoff for the 100 making all three accommodating to a wide variety of runners.

The courses all start at the Bonneville Salt Flats Speedway, and run the same section of Salt Flats that the land-speed records are set each year at “Speedweek”. After 13 miles of salt and three miles of mud-flats, the runners connect up with the “Islands”, mountain peaks that rise out of the salt and seem to float like islands on a white sea. 50K runners will run out the flats to the Lone Post Aid Station at 16 miles, and then reverse the course for a “long 50K”. 50 Mile and 100 Mile runners will run along rolling hills and connect two and four significant climbs respectively along the remainder of the course, and the 100 milers will even cross into Nevada where the Donner-Reed Party left Utah on their way to their fateful encounter with the harsh Sierra Nevada Mountains. All three courses finish back at the start where plenty of salt awaits those who need a little electrolyte boost.

A 5K fun run was introduced in 2021 and participants had a ton of fun on our simple out & back course with no frills. This is perfect for family or crew who are waiting ultra runners to finish. Bib pickup is 10:30-11:30am & the 5k starts at NOON. Everyone will get a Salt Flats Endurance Runs tech shirt & bib number.
