Kenai River Marathon Course Details

The Kenai River Marathon presents a captivating 26.2-mile journey through the heart of Alaska's natural beauty. Starting in Old Town Kenai, runners embark on a loop course that seamlessly blends rolling hills with flat stretches, primarily on road and pavement. The race winds along the picturesque Unity Trail, linking Kenai and Soldotna, and offers consistent views of the Kenai River, renowned for its fishing spots.

As participants navigate the course, they are treated to the serene beauty of spruce forests and riverside trails, with occasional glimpses of the majestic, snow-capped Kenai Mountains. The marathon's timing during the peak salmon running season adds an extra layer of excitement, as runners may spot fishermen landing their catch along the way.

Despite its generally flat profile, the course's rolling hills and occasional inclines introduce a moderate challenge. The intimate setting, with its small field size and remote locale, provides a uniquely personal marathon experience, offering tranquility but with fewer spectators and support. Overall, the Kenai River Marathon is a scenic adventure that beautifully combines Alaska's natural splendor with the thrill of a marathon.
