Embark on an extraordinary adventure at the SISU 24 Ultra PNW, a truly unique "choose-your-own-adventure" endurance event set for June 27, 2026, in Enumclaw, Washington. Nestled in the breathtaking Cascade Mountains, near Mount Rainier National Park and Crystal Mountain, the race offers a stunning backdrop of towering cliffs, pristine waterfalls, and majestic wildlife. Participants can choose from a grueling 100-mile challenge with over 25,000 feet of elevation gain, or test their limits in a 24-hour solo or 3-person team event. With 100% un-paved trails featuring rocks, roots, and ruts, runners navigate six distinct out-and-back routes, each assigned points based on difficulty and distance, allowing for strategic race planning.

What truly sets the SISU 24 Ultra PNW apart is its dynamic format, encouraging runners to not only conquer challenging trails but also engage in a series of "side quests." These can range from midnight yoga and memorization tasks to connect-the-dots, trivia, and knot tying, all designed to earn additional points and keep the experience engaging. This event is built around a central base camp at Camp Sheppard, offering three days and two nights of inclusive camping for runners, their crews, and families, creating a supportive and festive atmosphere complete with movies and crafts. Aid is never far, as runners continually return to the base camp, though bringing a headlamp, hydration, food, and a water filtration device for trail water sources is required.

Known for its brutal yet awesome trails and incredibly supportive community, the SISU 24 Ultra PNW has a reputation as one of the toughest and most rewarding ultras. Typical race day conditions in late June bring pleasant highs around 71F and lows around 51F, with only a 15% chance of precipitation, providing ideal weather for an epic endurance challenge. This is more than just a race; it's an opportunity to forge unbreakable grit and create lasting memories.
