Background
This was the 24th appearance of the event, which is one of 12 athletics events to have been held at every Summer Olympics. Five of the finalists from 1996 returned: defending gold medalist Michael Johnson and fourth-place finisher Alvin Harrison of the United States, bronze medalist Davis Kamoga of Uganda, seventh-place finisher Davian Clarke of Jamaica, and eight-place Ibrahim Ismail Muftah of Qatar. Johnson had stretched his world championship streak to 4, set a new world record, and was the (overwhelming) favorite again in 2000. Both of the other medalists ( Sanderlei Parrela of Brazil and Alejandro Cárdenas of Mexico) from the 1999 worlds were in Sydney as well. Following the breakup of the Soviet Union, Lithuania and Ukraine appeared in this event for the first time; Russia appeared for the first time since 1912. The United States made its 23rd appearance, most of any nation, having missed only the boycotted 1980 Games.Qualification
EachCompetition format
The competition retained the basic four-round format from 1920. The "fastest loser" system, introduced in 1964, was used for the first round. There were 9 first-round heats, each with 7 or 8 runners. The top three runners in each heat advanced, along with the next five fastest overall. The 32 quarterfinalists were divided into 4 quarterfinals with 8 runners each; the top four athletes in each quarterfinal heat advanced to the semifinals, with no "fastest loser" spots. The semifinals featured 2 heats of 8 runners each. The top four runners in each semifinal heat advanced, making an eight-man final.Official Report, Results Book for Athletics.Records
