JTBC Seoul International Marathon invites runners from around the globe to experience one of Korea's most beloved races. This vibrant race winds through the heart of Seoul, featuring iconic landmarks and historic sites that tell the city’s rich narrative. From Deoksugung Palace with its stunning architectural details, past Dongdaemun Market, a bustling hub for fashion enthusiasts, and continuing on to Gwanghwamun Square where modern Seoul meets tradition, runners will also pass by locations significant in Korea's sporting history like World Cup Stadium and Olympic Park. The event is celebrated not only for its scenic route but also as the premier running festival for young adults. With 80% of participants falling within their 20s to early 30s, this marathon thrives on a youthful energy that keeps it fresh and exciting year after year. Top-tier global sportswear brands support the race annually, ensuring runners have access to cutting-edge gear. Both the full marathon and 10K events are highly sought-after; they sold out within hours of registration opening last year. This overwhelming demand led organizers to introduce a lottery system for entry this season, yet interest remains undiminished. Participants must collect their race packs at the expo before the event begins, requiring all runners to present valid passports that match the personal information provided during registration. Foreign residents are eligible to register exclusively through World's Marathon. This unique opportunity offers an unparalleled chance to explore Seoul’s dynamic blend of history and modernity while celebrating alongside thousands of enthusiastic young athletes from around the world.
