Embark on the Cascade Crest 100M, a legendary ultra-marathon renowned for its rugged beauty and formidable challenge. On July 17, 2026, runners will gather in Easton, WA, at the local fire station, for a 9:00 AM start, embarking on a clockwise, 100-mile loop through the breathtaking Wenatchee and Snoqualmie-Mt Baker National Forests. This iconic course boasts over 23,000 feet of elevation gain across a diverse landscape of 70% technical trails, 26% forest roads, and a small percentage of paved sections, making it a true test of endurance and grit. Typical race day conditions in mid-July offer pleasant highs around 71F and lows near 52F, with a minimal 8% chance of precipitation, providing a generally favorable environment for tackling the demanding terrain.

The Cascade Crest is celebrated as one of the most challenging mountain trail ultras in the United States, earning its reputation as a Pacific Northwest classic since its founding in 1999. The course highlights are as unique as they are demanding: approximately 30-32 miles trace the historic Pacific Crest Trail, offering stretches of runnable "buttery" trails amidst towering trees. However, runners must also contend with a surreal 2.5-mile passage through the dark, uphill Snoqualmie Tunnel, a thrilling rope-assisted descent, the notoriously difficult "Trail from Hell"—a six-mile section of roots, fallen trees, and steep rollers—and the demoralizing "Cardiac Needles," a series of intense, technical climbs and descents in the latter stages of the race. These distinct features, coupled with stunning views of Mount Rainier and the surrounding Cascades, create an unforgettable journey.

Beyond the challenging course, the Cascade Crest 100M is revered for its "old-school" feel and unparalleled community spirit. A strong field of runners is supported by an incredible network of dedicated volunteers at 16 full and two water-only aid stations, many of whom return year after year to create a vibrant and encouraging atmosphere. These well-stocked oases provide everything from water and electrolyte drinks to salty snacks, fresh fruit, sandwiches, hot soups, and even hot food like grilled cheese at various points. Runners frequently praise the exceptional support and camaraderie, which are integral to the race's identity. Finishing the Cascade Crest is not just a physical accomplishment, but a deeply personal one, leaving participants with a profound sense of achievement from conquering one of the region's most iconic 100-mile adventures.
