Usain Bolt wins ninth Olympic gold with 4 x 100m relay success

Jamaica have won gold in the men's 4 x 100m relay in Rio de Janeiro as Usain Bolt ended his Olympic career in style.

The legendary sprinter was aiming to earn his ninth gold medal at the Games since making his bow in 2008 and it never looked in doubt as he and his Jamaican teammates easily saw off the field.

Bolt ran the anchor leg to complete victory for a formidable team also made up of Asafa Powell, Yohan Blake and Nickel Ashmeade as they ran a time of 37.27s.

Japan and Canada won silver and bronze respectively, with Great Britain in fifth from the inside lane.
