About the race

SISU 24 PNW is a base-camp, 24-hour trail event on June 26, 2027, held near Mount Rainier National Park in Enumclaw, WA and organized by Side Quest Adventures. The event offers both solo and team formats and includes camping at Camp Sheppard for the weekend. Participants choose their own routes from six fully marked out-and-back trails. Trails range from approximately 3 to 19 miles and include forest paths, waterfalls, and long climbs.

Each trail has a rubber stamp at its farthest point; runners use an ink pad and quest log to prove completion and must check in and out at headquarters so staff can verify points and track safety. A dynamic point system rewards earlier completions more than later ones, creating multiple scoring strategies. Optional side quests appear throughout the weekend and reward creativity, teamwork, and problem solving; these tasks are voluntary and vary in type and difficulty. Race logistics include verified stamping and a check-in/check-out process. Required gear listed by the organizer includes a headlamp, hydration pack or bottles, water filtration or purification, food for the event, and an ink pad for the quest log.

Every participant receives a custom finisher award, and additional awards recognize top overall finishers, teams, mileage leaders, and a community-voted SISU Spirit Award. Visit the organization's website for the most recent information.
