LAS VEGAS (Nevada), Sept 26: American Lance Armstrong, making a return to professional cycling three years after winning his seventh Tour de France, said on Thursday his doping test results would be open to the public.

The Texan, who won the Grand Boucle from 1999 to 2005, was speaking during a press conference at a cycling exhibition in Las Vegas.

He said that he would be working with Don Catlin, the founder of the new Anti-Doping Research Institute in Los Angeles, in an attempt to be completely open about his tests.

He retired from professional racing the night he won his last Tour de France, but announced his return to the international cycling scene on September 9 this year.

On Wednesday, he confirmed he would be returning to the sport, aged 37, saying he would be riding for the Astana team, run by his old sporting director Johan Bruyneel.

Armstrong, in an attempt to lessen doubts that his seven Tour victories were won without doping, said: “I want to have a level of transparence and I don’t want to leave any hint of doubt. I will do what I am asked to do. It is his (Catlin’s) work. He will do whatever he wants (concerning testing). Catlin himself said: “Everything will be made public and everyone will be able to see the evolution of the results and see if there have been changes.” —AFP
