Rainbow Ridge 50k
Rainbow, United States • 11 Oct 2025
Rainbow Ridge 20k/50k is the inaugural ultramarathon in the Pacific Northwest near Rainbow, Oregon along the McKenzie River corridor. The event offers two rugged distances: 20k with a ~2,600-foot ascent to Kings Castle summit and a fast, single-track descent back to the upper McKenzie community center; and a 50k with roughly 7,000 feet of vertical gain, starting with a shuttle to Olallie North Trailhead, climbing Horse Pasture Mountain, traversing the ridgeline past Macduff Mountain, and finishing with a six-mile descent to the community center. Expect epic old-growth forest climbs, expansive 360-degree views of the Three Sisters and Cascade peaks, and a classic Pacific Northwest race atmosphere. Proceeds benefit Bridgeway House, with swag from Territory Run Co. Visit the organization's website for the most recent information.
