Usain Bolt brought the curtain down on his Olympic career with a record-equalling ninth gold medal on Friday, anchoring Jamaica to relay glory in a perfectly-scripted finale to complete his unprecedented “triple-triple.”
The 29-year-old superstar, widely seen as the greatest sprinter in history, stormed over the line in 37.27sec to trigger an eruption of adulation in the Olympic Stadium.
Japan’s quartet took a surprise silver in 37.60sec while Canada took bronze after the United States, who crossed in third, were later disqualified.
The victory saw Bolt complete a third consecutive clean sweep of the 100m, 200m and 4x100m titles following his six gold medals in the 2008 and 2012 Games.
It leaves Bolt – who will retire in 2017 – level with Carl Lewis and Paavo Nurmi on a total of nine Olympic gold medals, a record for a track and field athlete.
