Jamaican sprint king Usain Bolt has confirmed he will run the 100 metres and 4x100m relay at the 2017 International Association of Athletics Federations (IAAF) World Championships, which will be his last event before retiring.

The 30-year-old multiple Olympic and world champion has already gone on record to say he plans to quit the sport after the Championships, scheduled to take place here from August 4 to 13.

The men's 100m final is due to take place on August 5, while the men's 4x100m relay race - which will mark the end of Bolt's career - is scheduled for August 12.

"My aim is to win in London," Bolt said today.

"I want to retire on a winning note."

Last month, Bolt won his final race on home soil, at the Racers Grand Prix in Jamaica’s capital Kingston, in 10.03sec.

He is due to compete in the 100m at the IAAF Diamond League event in Monaco on Friday (July 21).

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

He lost his 4x100m gold from Beijing 2008, however, after another member of the winning quartet, Nesta Carter, failed a drugs test for banned energy boosting substance methylhexaneamine following re-analysis of frozen samples.

Michael Frater and Asafa Powell were also stripped of their gold medals.

The team have all returned their medals to the International Olympic Committee.

Earlier this month, Jamaica’s independent anti-doping disciplinary panel revealed that Jason Livermore has tested positive for a banned substance.

The 29-year-old was part of the team that won 4x100m relay gold at the 2014 Commonwealth Games in Scottish city Glasgow alongside Bolt, Kemar Bailey-Cole and Nickel Ashmeade.

Livermore also won individual 200m bronze in Glasgow.

The illegal substance found has not been named, but Livermore returned the positive test on December 16.

A full hearing has been scheduled for September 11.

The IAAF World Championships follow the ongoing World Para Athletics Championships, which are due to conclude here on Sunday (July 23).

London 2017 marks the first time ever that both the World Para Athletics Championships and IAAF World Championships are being held in the same city in the same summer.
