Usain Bolt captured a third gold medal and a third world record after Jamaica claimed the men's 4x100m relay gold. The quartet smashed the previous world mark of 37.40 seconds set by the United States at the 1992 Olympics by a huge margin to set a new benchmark of 37.10. Nesta Carter ran a strong first leg before passing the baton to Michael Frater, who handed on to Bolt before Asafa Powell brought it home. Trinidad and Tobago took silver with Japan coming home for bronze
