Michael Johnson

Michael Johnson is one of the greatest sprinters of all time, and in the 1990s he dominated the 200m and 400m, going undefeated in the latter for seven years. Born in Dallas in 1967, he studied at Baylor University and was spotted by coach Clyde Hart. After gaining a degree, he committed to full-time athletics and in 1991 won the 200m world title. Sadly, food poisoning denied him individual success at the Barcelona Olympics, but he helped the US 4x400m relay team to gold. From 1993, Johnson went undefeated in the 400m for 58 races and in 1996 achieved the 200m-400m double at the Atlanta Olympics, setting world records in both. He retired in 2001 having won 8 world and 4 Olympic gold medals.
