Here is what the website says about the course:
This is a fast, predominately flat course on pavement. The marathon route has been certified by USATF (Certification AK08002FW). Course begins with a run through Old Town Kenai allowing runners to take in a short but delightful look at the mouth of the Kenai River and the Kenai mountains. Once out of town, the course primarily follows the Unity Trail connecting the cities of Kenai and Soldotna, crossing the Kenai River twice. The course meanders through the residential area of Soldotna before connecting again with the Unity Trail along the Kenai Spur Hwy bringing runners back into Kenai for the finish at the Kenai Visitors & Cultural Center.
