The chairman of the World Anti-Doping Agency has reminded cycling legend Lance Armstrong that he can still dispel rumours of past doping offences by accepting the re-testing of his 1999 Tour de France samples.
John Fahey says if there's a question mark hanging over him there is one way he could resolve that, but it requires Armstrong's permission, and the cycling legend refuses to give that permission.
In 2005, shortly after the US cyclist retired - in what was to be a temporary move - the French sports daily L'Equipe reported that a retroactive test of urine samples taken from Armstrong during the 1999 edition of the Tour had found traces of the banned substance EPO.
The record seven-time tour de France winner always denied foul play, and he questioned the methods of the Paris laboratory that carried out the tests.
The cyclist said he cannot be sure that the samples had been properly preserved over the years.
