Course
All courses start at the Bonneville Salt Flats Speedway and run sections of the salt flats used for land-speed record attempts. The route includes about 13 miles of exposed salt followed by roughly 3 miles of mud-flats, then connects to the "Islands," which are mountain peaks rising out of the salt. The 50K uses an out-and-back to the "No Post" aid station at 15.5 miles for an exact distance. The 50 Mile, 100K and 100 Mile routes continue onto rolling hills and include multiple significant climbs; the 100 Mile course crosses into Nevada at a historical emigrant route point.
Awards
Each distance awards the top three overall men and the top three overall women. Visit the organization's website for the most recent information.
