About the Race
This event is Postponed to June 26, 2021. All current registrations will be forwarded to the new date
SISU ENDURANCE presents one of the most unique events on the planet. You have 24-Hour to explore and run any distance you like, with the opportunity to achieve one of the toughest 100-Mile races anywhere! We start at a private Boy Scout Camp (Camp Sheppard) located in the spectacular Cascade Mountains, just minutes from Mount Rainier National Park and Crystal Mountain ski area. Cliffs tower overhead, pristine falls can be found nearby, and giant elk freely roam the meadows.
You are encouraged to come Friday and set up your base camp. Bring the entire family, crew, or friends – all extra support team are free and encouraged! Kids love camping for the weekend at the Boy Scout Camp! Saturday morning the race starts. Everyone races together, the 100-Mile runners go out with 24-Hour Individual and 24-Hour Team runners. The race ends Sunday, 24-Hours after it begins for the team and individual runners. For the 100-Mile runners, there is a 32-Hour cutoff. If an individual or an individual of a team achieves 75 miles during the course of their 24-hour race, they may elect to carry on.
This race is self-supported. You have a base camp. We encourage everyone to be festive and creative with your camp. We will have movies as well as arts and crafts for the family! There are multiple loops all leaving from base camp. The longest distance is 18.5 miles, and the shortest approximately 3.5 miles. Every time you head out you check in at the head table which is at base camp. You choose which loops you want to do, and how many you desire! There are also challenges throughout the 24 hours if you desire such as midnight yoga, and community service.
At the end, points are earned by your route choices and any extra challenges you complete. There are also bonuses for those who complete a majority or all of the trail routes. You are never too far from base camp and your gear/fuel/food. There will be a food truck at camp as well as an espresso cart! The mood is festive with lights, movies, crafts, and onesies.
