Ben Johnson's 100m Disqualification (1988)

Canadian sprinter Ben Johnson won the 100m final at the 1988 Seoul Olympics in a world record 9.79 seconds — only to be stripped of his gold medal three days later after testing positive for stanozolol. The race, once called "the dirtiest race in history," later saw six of the eight finalists linked to doping. Johnson's downfall made him the face of drug cheating in sport, but the subsequent revelations about his competitors raised the uncomfortable question: was he simply the one who got caught?
