 The final was the first to have five men going under 20 seconds but despite this Bolt was two metres ahead of the field coming of the bend and just kept on running.On 21 August double Olympic champion Veronica Campbell-Brown couldn't replicate Bolt's 200 m success as she won silver in the 200 m final behind American Allyson Felix in a time of 22.35.On day eight of the Championships was the day of the sprint relays and the women's 4x100 m was without United States meaning that Jamaica were clear favourites as long as they got the baton round which is what they did as the team of Simone Facey 200 m finalist, Shelly-Ann Fraser 100 m gold medalist, Aleen Bailey 100 m finalist and Kerron Stewart 100 m silver medalist on the final leg ran 42.06 to win Jamaica's 6th gold medal.
