The Gorge Waterfalls 100K, taking place on April 11, 2026, in scenic Cascade Locks, Oregon, offers an unparalleled journey through the heart of the Columbia River Gorge National Scenic Area. This 100-kilometer (62-mile) ultra-marathon is a world-class scenic tour, immersing runners in a landscape of lush, moss-draped forests, sweeping views of the Columbia River, narrow cliffside trails, and countless cascading waterfalls, including iconic Multnomah and Wahkeena Falls. The course is an out-and-back route, starting and finishing at Marine Park Pavilion, and challenges runners with approximately 11,000 feet of elevation gain and loss over varied terrain. Expect a mix of rocky, semi-technical singletrack, smoother dirt paths, and intermittent sections of paved pedestrian/bike connectors and rural roads, requiring both focus and grit. With typical race day conditions seeing highs around 58°F and lows around 41°F, and a 34% chance of precipitation, runners should be prepared for potentially volatile weather and slippery, muddy sections, adding to the race's demanding nature.

The Gorge Waterfalls 100K is renowned for being a challenging yet runnable course, punctuated by numerous punchy hill climbs and technical sections that demand sustained effort. It's a qualifying race for the prestigious Western States Endurance Run, requiring a sub-17-hour finish, and is also a UTMB Index race. Runners can rely on eight "full service" aid stations, strategically placed along the route, offering a wide array of sustenance from Neversecond gels and hydration to PB&J sandwiches, fresh fruit, and warm, savory options at later stations. These stations are staffed by enthusiastic volunteers, contributing to the race's celebrated atmosphere and comprehensive support. Participants are encouraged to bring their own reusable drinking vessels as the event is cupless.

This event, organized by Daybreak Racing and Freetrail, is celebrated for its professional execution, vibrant community spirit, and spectacular natural setting, making it one of the most popular and well-supported trail races in the United States. The Marine Park staging area in Cascade Locks provides excellent amenities, including ample parking and even participant camping options on Thunder Island. While not an entry-level 100K, experienced ultra-runners consistently praise the Gorge Waterfalls for its stunning scenery and well-managed challenges, calling it "well-managed and just so gorgeous." Be ready for an unforgettable adventure where the beauty of the Pacific Northwest converges with the ultimate test of endurance.
