Thunder River : November 8, 2025
Thunder River is a trail race staged from Marine Park in Cascade Locks, Oregon, in the Columbia River Gorge. The event offers two courses: a purely point-to-point 25K and a mostly point-to-point 50K. Both courses use sections of the Pacific Crest Trail and the Gorge 400 trail, pass under the Bridge of the Gods into Cascade Locks, include a trail loop around Thunder Island in the final mile, and finish at the Marine Park staging area. The race takes place in fall and the course passes through areas with seasonal colors and river views.
