Come join us for the 3rd annual Run the River Marathon, starting at Columbia Park in Kennewick, WA. This road race features a scenic course that travels through the towns of Kennewick, Richland, and Pasco all while staying next to the mighty Columbia River.

This classic road marathon follows paved paths and roadways the entire time and offers participants with great views of beautifully landscaped parks, the meandering Columbia River, as well as the rugged surrounding mountains. The flat course and cool spring weather will provide runners with a prime opportunity for a fast finish time if that is their goal. Likewise, the course lends itself well to runners of all abilities as well as walkers... which tend to have the best time out there!

For those that aren't wanting the full marathon distance, there are a few other options. You can gather up some friends and do the 4-person relay option, which covers the entire marathon course, or you can do the half marathon or 5k options instead.

New for 2025, there will be a kids marathon where you run 25 miles on your own before race day and then 1.2 miles on race day to finish the full marathon distance. More details will be provided in the future about this exciting event.

Spring in the Tri-Cities can bring a mix of sun, rain, and wind - it just depends on the year. Please watch the forecasts as it gets closer to race day to make sure you are prepared. Since the course makes a large loop, any wind encountered should only be for a limited time. Over the last twenty years, the temperature at start time has varied between 43°F and 62°F, with an average of 51°F.
