Thunder River

This trail running event takes place on a Saturday in November in Cascade Locks, Oregon. The event is organized by Daybreak Racing and is staged at Marine Park, which is approximately a 40-minute drive east of Portland. The park is along the banks of the Columbia River.

The event offers two race distances: a 25K and a 50K. Both courses use sections of the Pacific Crest Trail and the Gorge 400 trail. The 25K course is purely point-to-point. The 50K course is mostly point-to-point. Both races finish with a trail loop around Thunder Island before concluding at Marine Park.

The event marks the end of the organizer's event season and takes place before winter weather sets in. Visit the organization's website for the most recent information.
