Usain Bolt confirms retirement after two races in London

Usain Bolt has confirmed he will retire after running two races in London.

The Jamaican will compete in the 100m and 4x100m relay at the World Championships in London in August before hanging up his running shoes.

The 30-year-old is an eight-time Olympic gold medallist and an icon of world sport.

He said: "My aim is to win in London. I want to retire on a winning note."

The World Championships take place from 4-13 August.

The men's 100m final is scheduled for Saturday, 5 August, while the men's 4x100m relay race - which will mark the end of Bolt's career – is due to take place on the following Saturday.

Bolt has won the 100m, 200m and 4x100m gold at the past three Olympic Games - Beijing 2008, London 2012 and Rio 2016.

However, his unprecedented 'triple triple' of nine gold medals was downgraded to eight after Jamaican team-mate Nesta Carter, who was part of the quartet that won the 4x100m in Beijing, tested positive for a banned substance. The decision has been appealed by Carter.
