Usain Bolt Becomes Olympic Immortal As Jamaica Wins 4x100m Relay Gold

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.

Usain Bolt's 'triple triple'  came on the eve of his 30th birthday.

According  to publication, Bolt confirmed in February he would retire after the 2017 World Championships in London and will not compete at Tokyo 2020, at which point he will be nearly 34.

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.
