Lance Armstrong urged 'to come clean' by former team-mate and drug cheat Tyler Hamilton The evidence is out there. Lance and I were team-mates for four years. I saw it. We doped together. Hopefully he'll just come out with the truth. I think it'll be better for the sport and actually better for him. I think he'll feel a lot better when he comes to terms with the truth. Hamilton won a time trial gold at the 2004 Olympics, but later was twice handed doping bans. In 2011 he admitted to using banned substances in competition and was formally stripped of his Olympic medal the following year. Hamilton said he and his team-mates were give the tools to keep one step ahead of the anti-doping testers. "Looking back I wish the tests were better back then," he said. We had sophisticated doctors, working for the riders. Our doctors were always one if not two steps ahead of the drug testing. They knew how to beat them. We just followed the simple rules they gave us and if we followed those simple rules you basically 99 if not 100 times out of 100 would test negative.
