Suh Yun-bok — 1947 Boston Marathon winner and South Korean marathoner

Overview

Suh combined a compact stature and light frame with endurance and tactical pacing. Listed at about 166 cm and 56 kg, he was among the smaller elite marathoners of his time. His Boston victory in 1947 was notable not only for the win itself but because the performance was recognized as the fastest marathon time in the world that year. Financial support for his appearance in Boston came in part from donations collected by servicemen with the United States Forces in Korea, reflecting the international connections shaping sport in the postwar era.

1947 Boston Marathon

On his trip to the United States, Suh competed in the Boston Marathon and finished with a clocked time of 2:25:39, which at the time was reported as a world best. His coach, Sohn Kee-chung, had himself held a previous world-best mark set in Tokyo in the mid-1930s. Suh's win marked the first time a world-best marathon time was recorded at the Boston event and brought international attention to Korean distance running.

Olympic participation and later career

Following his Boston success, Suh represented Korea at the 1948 Summer Olympics in London where he ran the marathon as part of the national team. Although he did not reach the Olympic podium, his presence at the Games was significant for a newly independent Korea building its international sporting identity. Suh retired from competitive running around 1949 and later lived in Seoul, where he died in June 2017 at the age of 94.

Style, training, and significance

Trained by Sohn Kee-chung, Suh's preparation emphasized long-distance mileage and practical pacing strategies typical of mid-20th century marathon training. Without modern sports science, his accomplishments relied on discipline, experience, and the mentorship of a previous Olympic champion. Suh's Boston record and international appearances helped inspire interest in marathon running in Korea and contributed to a national tradition that produced later international competitors.
