Usain Bolt cemented his place in Olympic folklore by claiming a second three-gold medal haul in successive Games as Jamaica stormed to a world record-breaking 4x100m relay victory on Saturday.
It was the perfect send-off to a track and field programme at the Olympic Stadium dominated by Bolt, who became the first athlete in history to successfully defend his Olympic 100 and 200m titles earlier this week.
His part in the podium-topping relay team means he has now replicated his treble gold showing in the Beijing Games in 2008.
The quartet of Nesta Carter, Michael Frater, double Olympic sprint silver medallist Yohan Blake and Bolt scorched to 36.84sec, beating their previous record of 37.04sec set in the 2011 worlds in Daegu.
The United States claimed silver in a national record of 37.04sec, with Trinidad and Tobago taking bronze in 38.12sec after Canada were disqualified.
