Participants can choose from three challenging distances—50K, 50 miles, and 100 miles—starting at the Bonneville Salt Flats Speedway, known for its land-speed records. The route traverses 13 miles of salt flats and 3 miles of mud, leading to the "Islands," stunning mountain peaks that appear to float above the white landscape. 50K runners will head to Lone Post Aid Station before reversing, while 50-mile and 100-mile participants will encounter rolling hills and significant climbs, with the latter even crossing into Nevada on their epic journey. All courses culminate back at the start, offering a unique electrolyte boost from the abundant salt.
