Seo Yun-bok

Suh Yun-bok (1923–2017) was a South Korean marathon runner. In 1947, coached by Sohn Kee-chung, he ran the 51st Boston Marathon and, at age 24, won in a world-record time of 2:25:39, becoming the first Asian athlete to take the title. Achieved on the international stage shortly after Korea's liberation, the victory is remembered as a milestone that made the name of the young Republic of Korea known to the world. He went on to represent Korea at the 1948 London Olympics and, after retiring, worked as a track-and-field coach.
