South Korean archer Park Seong-Su was a surprise pick for the national team at his home Olympics in 1988 in Seoul. Park went on to justify his selection by winning gold in the team event with compatriots Lee Han-Seop and Jeon In-Su, as well as silver in the individual event. In 2000 he became a coach in the sport, eventually coaching the national team in 2004. At the 2012 London Olympics he helped coach Oh Jin-Hyeok in winning the gold medal.
Park’s greatest achievement as a coach came in 2024, leading the South Korean team to a clean sweep of gold medals in all five events at the Paris Olympics.
