What Makes It Great

A 50-mile loop beginning with 17 miles across the Bonneville Salt Flats and compacted desert sand, then looping through the southern Silver Island Range via two significant mountain climbs on narrow, rocky 4x4 jeep tracks. After a technical descent, runners return to the salt for the final miles to the finish. With only two crew-accessible aid stations, self-sufficiency is important. Finishes Friday evening with a 14-hour cutoff.
