American Lance Armstrong, making a return to professional cycling three years after winning his seventh Tour de France, said today 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.
Armstrong said 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.
Armstrong confirmed this week 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.
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.
"What will happen? His samples will also be frozen for analysis in several years time if need be."
Armstrong has been accused of doping practices on several occasions, most notably in an article in French sports newspaper L'Equipe in 2005, claiming six urine samples from his 1999 Tour victory contained blood-boosting drug EPO.
The rider himself has always denied doping and the sport's world governing body, the UCI, cleared him in 2006.
On his racing schedule, Armstrong had said earlier: "I said (on Wednesday) I was going to participate in the Tour Down Under (in Australia at the end of January) and the Tour de France (in July). I can now add that after the race in Australia, I'll get back into training and then race in the Tour of California."
Armstrong, who was treated for testicular cancer in 1996, has continually claimed his comeback, which will be for at least one year, was to raise awareness of cancer through his "Livestrong" cancer prevention campaign.
"I have no contract, no wages and no bonuses," Armstrong said.
"Everything is being done as a type of donation. It will be for at least a year but it could be longer. It depends on how the campaign (cancer awareness) goes."
Armstrong, who rode in a cyclo-cross event on Wednesday night, said his reasons to make his comeback with Astana was because of loyalty to Bruyneel, who helped him to his seven Tour wins.
"To have my own team (Livestrong) would have been too complicated," Armstrong added. "And I wanted to be loyal to Johan (Bruyneel). I would only have made a comeback with him."
