Usain Bolt ended his Olympic career by claiming an unprecedented ‘triple triple’ and his ninth gold as Jamaica won the 4x100m relay final in Rio.

Bolt, 29, had won the 100m and 200m in Rio and is the only man to win all three sprint events at three Games.

He combined with Asafa Powell, Yohan Blake and Nickel Ashmeade to finish in 37.27 seconds.

Japan won a surprise silver.

In February, Bolt confirmed he would retire after the 2017 World Championships, meaning Rio marks the end one of the greatest Olympic careers of all time.

His haul of nine gold medals is the joint highest among Olympic athletics, equal with USA sprinter and long jumper Carl Lewis and Finnish long-distance runner Paavo Nurmi. (BBC)
