第30回国境マラソンIN対馬 2026

The Kokkyo Marathon in Tsushima takes place in June, starting at Miuda Beach in Kamitsushima, Nagasaki. This beach is one of Japan's 100 best. Participants can select a half marathon (21.0975 km) or a 7.1 km race. The half marathon begins earlier and has a 3-hour time limit. The course presents a challenge for a beachside event, featuring significant elevation changes instead of a flat, waterside path. Runners are treated to expansive views of the sea and sky. This event is considered a significant local race in Tsushima. Entry is open to healthy individuals aged high school level and above. Guide runners are permitted for those requiring assistance, and awards extend to top finishers in each category, along with special prizes.
