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

Saturday, May 13, 2023 • Astoria, OR • Course Map

You’ll get the chance to run what some observers have called the “yellow brick road” of Astoria at the Run on the River Half Marathon, which unfolds along the five-mile-long Astoria Riverwalk here in this city located on the mouth of the Columbia River, where it empties into the Pacific Ocean.

Run the old Burlington Northern Railroad. The Riverwalk was built on the abandoned tracks of the old Burlington Northern Railroad, which closed up its operations in the Astoria area decades ago but left behind its tracks along the Columbia River.

In the 1980s the tracks were converted into a running, walking and hiking trail, and even today you can see signs of the old tracks, especially when you run the stretch of the race on wooden surfaces where the tracks once lay.

Out-and-back. The race begins at the riverwalk at 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.
