Corvallis Half Marathon & 5K

The Corvallis Half Marathon’s 15th yearly event back on April 11th 2026.
The race starts and ends in Parker Plaza, which is between Gill Coliseum and Reser Stadium on the Oregon State University. The race winds through neighborhoods in north Corvallis, then into rural Benton County, around the Benton County Fairgrounds onto the Campus Way bike party and through the Irish Bend Covered Bridge.
This scenic, 13.1 mile 'Tour de Corvallis' is mostly flat with two slow gradual climbs, and two gradual descents.
The entire course is on paved roads, sidewalk and bike paths.
The 5k is one of the flattest around. You can expect a PR on this course!
