Athletics at the 1988 Summer Olympics – Men's 100 metres
The men's 100 meters at the 1988 Summer Olympics in Seoul, South Korea saw world champion Ben Johnson of Canada defeat defending Olympic champion Carl Lewis of the United States in a world record time of 9.79, breaking his own record of 9.83 that he had set at the 1987 World Championships in Rome. Two days later, Johnson was stripped of his gold medal and world record by the International Olympic Committee (IOC) after he tested positive for stanozolol. The gold medal was then awarded to the original silver medalist Lewis, who had run 9.92. On 30 September 1989, following Johnson's admission to steroid use between 1981 and 1988, the IAAF rescinded his world record of 9.83 from the 1987 World Championship Final and stripped Johnson of his World Championship gold medal, which was also awarded to Lewis, who initially finished second. This made Lewis the first man to repeat as Olympic champion in the 100 metres (second, if Archie Hahn's 1906 Intercalated Games title is recognized).
