Since the Sydney Olympics major championships honours had been split between 1992 and 1996 Olympic Champion Aleksandr Popov and Pieter van den Hoogenband who won in 2000. The possibility of a final showdown between the two men in Popov’s last championship appearance ended at the semi-final stage where Popov was touched out of a place in a final by 0.02 seconds. The South African pair of Roland Schoeman and Ryk Neethling took out the pace over the opening half of the race but Dutchman Van den Hoogenband kicked on in the later stages to successfully defend his Olympic title. Schoeman held on for silver but Ian Thorpe narrowly prevented Neethling joining his South African compatriot on the podium.
