Race Information
The Run the River Marathon 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 race follows paved paths and roadways the entire time and offers participants great views of 3 beautifully landscaped parks, the meandering Columbia River, as well as the rugged surrounding mountains. The flat and fast course and cool spring weather will provide runners with a prime opportunity for a fast finish time if that is their goal. The marathon is a Boston qualifier. The half marathon and 5k are certified courses. Likewise, the course lends itself well to runners of all abilities as well as walkers, who tend to have the best time out there! For those not wanting to run a marathon, the race also offers a relay, half marathon, 5k, and a kids marathon!
