This was the 12th appearance of the 200 metre freestyle event. It was first contested in 1900. It would be contested a second time, though at 220 yards, in 1904. After that, the event did not return until 1968; since then, it has been on the programme at every Summer Games. Four of the 8 finalists from the 2000 Games returned: gold medalist
Pieter van den Hoogenband of the Netherlands, silver medalist
Ian Thorpe of Australia, seventh-place finisher
Rick Say of Canada, and eighth-place finisher
Grant Hackett of Australia. Thorpe and van den Hoogenband had finished first and second, respectively, at both the
2001 and
2003 World Championships. American
Klete Keller had taken third in 2001, with Hackett earning bronze in 2003. Added to this already strong field was
Michael Phelps—an individual medley specialist who had set an American record in the 200 metre freestyle as the lead leg at the 2003 World Championships (not swimming the individual event there) and beaten Keller by six-tenths of a second at the U.S. trials. The Cayman Islands, Chile, Georgia, Latvia, Macedonia, Morocco, and Serbia and Montenegro each made their debut in the event. Australia made its 12th appearance, the only nation to have competed in all prior editions of the event. ==Competition format==
