Sisu 24 Ultra PNW

SISU 24 PNW is a self-supported, 24-hour endurance challenge at Camp Sheppard in the Cascade Mountains near Enumclaw, Washington, close to Mount Rainier National Park and Crystal Mountain. Runners select from six marked trails (3–18.9 miles) and earn points by completing routes, stamping proof at checkpoints, and tackling optional side quests, including Midnight Yoga, with some athletes aiming for the ultimate 100‑Mile Adventure under around a 32-hour limit. The weekend centers on base-camp life—three days of camping, restrooms and showers, and a festive atmosphere with lights and activities.

Awards include wood medals, top male/female and team honors, a 100‑Mile buckle, and a spirit prize. Visit the organization's website for the most recent information.
