Format and race rules
The event uses a backyard ultra format. Each official lap measures the yard distance and must be completed within the hour. Participants who complete the lap continue into the next hour. The 1-mile event is scheduled to run for 24 hours; after 24 hours a tie-breaker procedure adds one mile per additional hour until only one participant remains. The winner is the last person able to complete the yard within the hour. Additional course maps and event rules are available from the organizer.
