By the mid-80s, he had established himself as Canada’s faster runner, and had broken all Canadian sprint records. He won Gold at the World Indoor Championships in Paris and at the World Cup in Canberra in 1985, and Bronze in the 200-meter sprint at the Commonwealth Games in Edinburgh in 1986. Sadly, he is most widely remembered for being stripped of his Gold Medal for the 100 meters in Rome in 1987 and his Gold Medal for his record breaking sprint at the Olympics in Seoul in 1988, after testing positive for steroid use. He also is famous for having a heated rivalry with fellow sprinter Carl Lewis.
