Ham Kee-Yong (함기용), Song Gil-Yoon (송길윤), and Choi Yun-Chil (최윤칠) - in April 1950, two months prior to the start of the Korean War, these three Korean athletes achieved the astounding Korean Podium Sweep at the 1950 Boston Marathon. The first place finisher Ham was reportedly coached by the first Korean Olympic Marathon Champion, Sohn Kee-Chung (손기정), who won gold at the 1936 Berlin Olympics.
It is noted that the first Korean to win at the Boston Marathon was Suh Yoon-Bok (서윤복) in 1947, who was also coached by Olympic Champion Sohn, and the last and only other Korean Boston Marathon winner is Lee Bong-Ju (이봉주) in 2001 (with Lee also winning the Olympic silver medal at the 1996 Atlanta Olympic Games).
