Topping the charts in inspiration and popularity, the Cutthroat Classic provides incredible mountain views along a spectacular section of high alpine trail. The Cutthroat course is an 11-mile singletrack trail run through the North Cascades, following the iconic Pacific Crest Trail up and over Cutthroat Pass. This year's race will be September 6, 2025 and is limited to 400 participants. It sells out early every year, so don't wait to register.
