Organized by JTBC, the Seoul Marathon returns on November 2, 2025, featuring both a certified full marathon and a shorter 10 km event that showcase the best of Seoul. Runners in the full marathon will traverse a flat, fast course starting from Sangam‑dong’s World Cup Park and finishing at Olympic Park after crossing multiple bridges along the Han River. The 10 km race begins separately from Yeouido Park, designed for fitness runners and community participants. Known for its fast times and memorable city scenery, the event welcomes both competitive athletes and casual participants, all supported by pacers, race tracking, medical aid, hydration, and post‑race festivities. With over 25,000 runners expected, the JTBC Seoul Marathon is one of Korea’s premier autumn road races.
