About
The Run the River Marathon and Relay takes place in Kennewick, Washington, in mid-April, on a course that crosses Kennewick, Richland and Pasco along the Columbia River. Runners pass three landscaped parks, with views of the river and the surrounding mountains. The marathon (26.2 miles) and a four-person relay both start at 7:30 AM, the half marathon (13.1 miles) at 8:30 AM and the 5K (3.1 miles) at 8:45 AM. The marathon runs on paved paths and roads. The flat terrain and cool spring weather create good conditions for a quick finish, and the event is accessible to runners and walkers of all levels.
