When Johnson broke the world record for the 200 meter dash at the Summer Olympics in Atlanta in 1996, he ran the first 100 meters in 10.12 seconds. As incredible as it may sound, he ran the second 100 meters in 9.19 seconds which, as of October 15, 2007, is .55 seconds below the world record in the 100 meter dash. Historians have compared that run with the long jump of Bob Beamon in the 1968 Summer Olympics in Mexico City where he broke the existing world record by 21 3/4 inches or .55 meters. He had a running start for the second 100.
Wilma Rudolph's automatic timed world record in the 100 meter dash, 11.41 seconds set at the 1960 Olympics in Rome, was bettered by Wyomia Tyus at 11.23 seconds at the 1964 Olympics in Tokyo. She had run faster times but those races were not automatically timed. Her best 100 meter dash time was a hand timed 11.2 set at a meet in Stuttgart in 1961. Wilma's automatic timed world record in the 200 meter dash, 22.30 seconds set at the 1960 Olympics, was bettered by Edith McGuire at 22.05 seconds set at the 1964 Olympics.
The 200 meter dash made its debut in the Olympics at the 1900 Games in Paris.
