A 200 metres race is a sprint running event. On an outdoor 400 m track, the race begins on the curve and ends on the home straight, so a combination of techniques are needed to successfully run the race. A slightly shorter race, called the stadion and run on a straight track, was the first recorded event at the Ancient Olympics. The 200 m places more emphasis on speed endurance than shorter sprint distances as athletes rely on different energy systems during the longer sprint.
In the United States and elsewhere, athletes previously ran the 220-yard dash (201.168 m) instead of the 200 m, though the distance is now obsolete. The standard adjustment used for the conversion from times recorded over 220 yards to 200 m times is to subtract 0.1 seconds,[1] but other conversion methods exist.
The race attracts runners from other events wishing to double up and claim both titles. This feat has been achieved nine times at the Olympic Games, most recently by Jamaica's Usain Bolt in 2008. An Olympic double of 200 m and 400 m was first achieved by Valerie Brisco-Hooks in 1984, and later by Michael Johnson from the United States and Marie-José Pérec of France both in 1996.
The men's world record holder is Usain Bolt, who ran 19.19 s at the 2009 World Championships. The women's world record holder is Florence Griffith-Joyner of the United States, who ran 21.34 s at the 1988 Summer Olympics. The reigning Olympic champions are Usain Bolt and Veronica Campbell-Brown, both of whom are from Jamaica.
Because humans use the same muscles for both support and forward speed, the runners in the inside lanes are disadvantaged by centrifugal force during the bend phase. Consequently, the middle and outer lanes are preferred.[2]
