Third gold for Bolt
Usain Bolt completed his hat-trick of sprint titles at the World Championships tonight.
Bolt ran the third leg as Jamaica's 4x100 metre relay team stormed to victory in a championship record of 37.31 seconds in the Olympic Stadium.
Trinidad and Tobago took silver in 37.62secs with Britain's quartet of Simeon Williamson, Tyrone Edgar, Marlon Devonish and Harry Aikines-Aryeetey third in 38.02.
With the Americans disqualified, that left the minor medals up for grabs, but Jamaica had rested Bolt and Asafa Powell in the heats and were always red-hot favourites to win with the individual 100m gold and bronze medallists restored to the side.
"I wasn't really thinking about getting three gold medals because I could be in better shape," insisted Bolt, who broke his own world records in the 100m and 200m with times of 9.58 and 19.19 respectively.
