25K

The Thunder River 25K is a purely point-to-point Gorge tour — a fast, scenic route built for runners who want a big-view day without the 50K distance. The course follows a mix of classic Gorge trail, delivering fall color, river views, and that windswept, dramatic terrain the area is known for.

After passing under the Bridge of the Gods into Cascade Locks, you’ll wrap up with a loop around Thunder Island and finish at Marine Park.
