How entry works

Overseas runners register through the Dong-A Marathon Club shop on a set opening date (September 1, 2026 for the 2027 race). The full marathon requires an officially recognized race record under 4:59:59 from January 1, 2024 to November 30, 2026; the 10K does not. Korean residents register on a separate staged schedule.
