Run on the River Half Marathon, 10K & 5K

Sunday, May 20, 2018 • Astoria, OR • Course Map

Get your run on and help fund scholarships for low income families and individuals to access recreation programs at the 5th annual Run on the River Half Marathon, 10K & 5K in 2018.

The half marathon begins at 9:00 AM at the Astoria Riverwalk off 6th Street, and from there the course leads runners along the riverfront, heading west for the first three miles before making a turnaround and running east past the start and finish line again.

Much of the course provides beautiful riverfront views along the Columbia River that forms the border between Oregon and Washington. This along with the flat course makes Run on the River an excellent half marathon choice for beginners and those seeking to set a PR.

The course is open until 1:30 PM, and the 4 hours, 30 minutes course limit makes the event welcoming to walkers.
