At the 1996 Atlanta Olympics on August 1, Michael Johnson delivered a groundbreaking performance in the men's 200m final, setting a new world record of 19.32 seconds, surpassing his previous mark of 19.66 set five weeks earlier. Johnson's victory completed an unprecedented 200m-400m double at the Games, having won the 400m three days earlier in 43.49 seconds with an Olympic record. His second 100m split in the 200m was reportedly 9.20 seconds. Frankie Fredericks of Namibia finished second with an African record of 19.68 seconds, and Ato Boldon of Trinidad and Tobago placed third in 19.80 seconds. Johnson missed the 4x400m relay due to a hamstring injury from the 200m final but described the world record as a “bonus” beyond making athletics history.
That same evening, Marie-José Pérec of France made Olympic history by winning the women's 400m final in 48.25 seconds, setting a new Games record. This victory made her the first woman to successfully defend the 400m Olympic title and the second woman to achieve the 200m-400m double, following Valerie Brisco-Hooks. Pérec narrowly beat Australia's Cathy Freeman, who finished second in 48.63 seconds.
