Mexican Ana Guevara had been dominant in the past two years, winning 23 consecutive races, among which was the 2003 World Championships. But she was finally beaten in the month before the Olympics by Bahamian Tonique Williams-Darling at a Golden League meet in Roma. Williams-Darling had placed only fifth at the 2003 Worlds, but in Zürich at the Weltklasse, she again defeated Guevara. In the final Williams-Darling was in the lead, trailed by Guevara and American Sanya Richards. Guevara made up ground on the turn and almost pulled even by 50 metres to go, but could never quite close the gap, as Williams-Darling defeated her for the third consecutive time. The bronze was won by Russia’s Nataliya Antyukh, who had not been a factor early on but finished with a rush to get third.
