Come join us for the 4th annual Run the River Marathon and Relay, 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 3 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!
