'Unhappy' Usain Bolt hands relay gold back to Olympic chiefs

Usain Bolt has handed back his relay 4x100m Olympic Gold from 2008 to the International Olympic Committee following Jamaican team-mate Nesta Carter's failed drug test.

Bolt's 'triple triple' of nine golds won at the 2008 Beijing Games, the 2012 Games in London and Rio 2016 have been officially struck from the record books after Carter was found to have failed a doping test after retrospective action was taken by the IOC.

Jamaica's relay team from Beijing of Bolt, the disgraced Carter, Asafa Powell, Michael Frater and Dwight Thomas have all handed their medals back to the Jamaica Olympic Association.

"It's rough that I have to give back one of my medals and I already gave it back because it was of course required by the IOC," Bolt told The Gleaner newspaper in Jamaica.

"I'm not happy about it, but it's just one of those things that happen in life. but I can't allow that to deter me from my focus this season, so I am focused but I am not pleased about the situation."

"I think I've still accomplished a lot, this hasn't changed what I have done throughout my career. I have worked hard and pushed and done things that no one have done before.

"I have won three gold medals over the 100m and 200m, which no one has ever done before."

An appeal could yet be launched to the Court of Arbitration for Sport with the costs estimated to be several million, but Bolt has not ruled out contributing to a possible appeal.

"That's up to my management there are a lot of variables so we will discuss that and see where we go from there, but if it's necessary (I will help).," said Bolt, who intends to retire after the World Championships in London in September.
