SISU 24 Ultra PNW : Enumclaw, WA

SISU 24 Ultra PNW is a self supported trail running event held at Camp Sheppard near Mount Rainier and Crystal Mountain. The event combines marked out-and-back trails, a points system for route choices, and optional side quests during a multi day camp experience. Registration includes three days of camping with access to restrooms, showers, BBQ stands, and sinks. The campground is about 40 minutes from the nearest city.

Race format and logistics are participant driven. Runners set up a base camp, check in at the timing table before each outing, and carry an ink pad and quest log to stamp at the furthest point of each trail. Participants must check out and check in for safety and tracking. Some trails take runners far from camp and must be completed end to end; shortcuts are not permitted.
