The race
The Gunsan Saemangeum International Marathon is a prestigious World Athletics-recognized road race that highlights the unique geography of South Korea's western coast. The course is celebrated for its flat, fast terrain, running alongside the world’s longest seawall (the Saemangeum Seawall) and offering expansive views of the Yellow Sea. Often held during the cherry blossom season, the race attracts international elites and thousands of recreational runners, blending a high-performance, record-chasing environment with a festive community atmosphere that showcases Gunsan’s modern landmarks and scenic coastal beauty.
