From the Organizer
We are thrilled to share these incredibly beautiful fall season races across the iconic Columbia River Gorge! With a purely point-to-point 25K race and super sweet 50k lollipop, world class scenery, autumnal vibes and epic views, Thunder River doesn’t cease to amaze. Each race course travels along the iconic Pacific Crest Trail and Gorge 400 trail before cruising under the Bridge of the Gods into the town of Cascade Locks. Both races conclude with a trail loop around Thunder Island surrounded by the mighty Columbia River, culminating with the finish at Marine Park. We simply can’t think of a better way to close out our event season!
Thunder River is staged at Marine Park in Cascade Locks, Oregon, nestled in the heart of the Columbia River Gorge. This event offers the perfect late season trail race getaway before winter weather settles in.
