The 27 year old American sprinter won the British Grand Prix in Gateshead on Monday recording a time of 10.15 seconds,  after which he told reporters;

“I have been running on one leg. I’ll have a couple more meetings then I’ll go and get surgery. I really believe I can get back to my best.”

Gay has been trading records and medals with Jamaican sprinter Usain Bolt since before the Beijing Olympics and is determined to provide a genuine threat to the triple Olympic gold medallist.

Gay refers to Bolt as ‘a great competitor’ and says he is looking forward to competing with the Jamaican throughout the remainder of his career.

The 22 year old Jamaican was joined in the final of the 100 metres at the IAAF World Championships in Berlin by US rival Tyson Gay and Jamaican team mate Asafa Powell, who finished second and third respectively.

Defending champion Gay recording an American all time best for the distance of 9.71 seconds, while the former world record holder Powell could only manage 9.84 seconds.

Britain’s Dwain Chamberlain recorded a season best of 10.00 seconds and finished in sixth place.

Bolt and Gay could  face each other again in the final of the  200metres, the heats start on Tuesday, with current record holder Bolt installed as favourite. Gay is currently struggling with a groin injury so is not certain to be involved.
