Race format and logistics
The event is self-supported from a base camp. Runners select trails, collect a rubber stamp at the furthest point of each route, and must check in and out at HQ before and after each run for safety and tracking. Points are awarded for completing the six main trails; point values change based on how many participants have completed each route. Optional side quests on trails and separate activities (examples: midnight yoga, memory tasks, connect-the-dots, carrying an egg, sudoku, knot tying) also award points.
Awards include a custom wood round medal for all participants, podium awards for top three male and female finishers and top three teams, a custom buckle for 100-Mile finishers, a SISU Spirit Award voted by racers, and a SISU Miles award for most miles in 24 hours. Participants may select a non-binary category at registration; separate non-binary awards require a minimum of five entrants. Required gear includes a headlamp, hydration, water filtration device, food for 24 hours, and an ink pad. Visit the organization's website for the most recent information.
