Race format and support
The event follows a backyard ultra format with a looped course. Each loop starts precisely one hour after the last. Competitors must be in the starting corral at the bell and must start each loop at the bell. Each loop must be completed within one hour to count, including the final lap. Personal aid during a loop is not allowed; common aid stations are permitted and one will be at HQ. Artificial aids, including trekking poles, are not allowed. The winner is the last person to complete a loop; other runners who finish before 32 miles are recorded as DNF. Supporter rules restrict access to the corral, limit phone contact with runners on course, and reserve the kitchen area for staff. Visit the organization's website for the most recent information.
