Switchback Sorrows 50k Trail Race
This single-day event takes place on October 10, 2026, at Riverside State Park near Spokane, Washington. The race is a 50k distance (about 31 miles) run on a looped trail course that features roughly 3,100 feet of elevation gain.
The route passes alongside the Spokane River and over the CCC Suspension Bridge, and it goes through ponderosa pine forest and areas of volcanic "haystack" rock. Trail surfaces include singletrack, riverside paths, and technical rocky sections, plus multiple winding switchbacks. Organizers list a 10-hour course time limit and a finish-line cutoff on the same day.
The event is described as crew friendly. The park layout allows support crews to meet runners at several designated points for gear changes and aid. Riverside State Park requires a Discover Pass for all vehicles. Day and annual pass prices are noted as $10 and $45 respectively, and passes are available at automated pay stations within the park or online.
Entry offers on the event listing show a price range in US dollars. The event is presented as a trail-focused race that highlights local natural features and provides multiple on-course support options for participants. Visit the organization's website for the most recent information.
