Gyengju, South Korea · Sunday 18 October 2026
Held in Gyeongju, South Korea in October 2025, this marathon takes runners through a region rich with historical significance. The setting combines cultural heritage with accessible natural terrain, making it a destination race that appeals to runners seeking something beyond the typical urban marathon experience. The course itself is a trail-based route with gentle rolling hills throughout its 42.2-kilometer distance. With only 86 meters of elevation gain across the entire race, runners won't face any sustained climbs, though the undulating terrain means there's rarely a truly flat stretch. The elevation profile ranges between 28 and 78 meters above sea level, which translates to the kind of rolling landscape that keeps your legs engaged without demanding the brutal effort of a mountainous course. Expect a steady, rhythmic effort rather than dramatic elevation changes, the sort of race where pacing consistency matters more than power hiking.
