100 Miler

The Salt Flats Endurance Runs started with our 100 mile event in 2007. We offer a premier 100 mile event, exposing the runner to the mind-bending terrain and extreme environment of the Salt Flats, Island Mountains, and Mud-Flats surrounding the Bonneville Speedway.  Finish in less than the 36 hour cutoff and the coveted Salt Flats Endurance Runs 100 Mile buckle is yours! 


50 Miler

The Salt Flats Endurance Runs also offers a premier 50 mile event, exposing the runner to the same mind-bending terrain and extreme environment of the Salt Flats, Island Mountains, and Mud-Flats surrounding the Bonneville Speedway.   The course will start with the 100 Milers and take the runner along the same course as the 100 Mile Endurance Run up to mile 23, where it diverts and heads back south, over two mountain passes, and returns to the flats for the finish.  The finish cutoff is 14 hrs, and every finisher receives the 50 Mile "mini-buckle" medal!


50K

In 2016 we introduced our new 50K option. It is proving to The 50K starts at the same time as the other events, at 7AM on Friday morning, and follows the 50/100 mile course for the first 16 miles.  At the second Aid Station the runners will reverse the course back to near the start for a 31.1 mile 50K.  The cutoff is a generous 8 hours accommodating runners of all abilities, and all finishers within that 8 hr span will receive the "mini buckle" medal!
