Format, facilities and rules

Runners complete a loop of 4.167 miles (6706 metres) each hour. A lap must be completed before the next hour begins and runners must be in the start area before the hour horn; failure to do so leads to disqualification or a DNF. Runners must start each loop and cross the line within 30 seconds of the start horn. A start corral is marked and whistles will sound shortly before each wave. No on-course support is allowed and competitors may not visit their tent or receive assistance after starting a loop. The route is fully marked. Race HQ offers a camping area adjacent to the HQ, an indoor area, wifi, USB charging, showers, changing rooms, and a small aid station with hot and cold drinks, liquids, fruits, sweets and snacks. Extra tables are provided for runners without a support crew. Visit the organization's website for the most recent information.
