Wu-oh. Floyd Landis had “an unusual level of testosterone/epitestosterone ratio” in his blood after stage 17 of the Tour de France. If his backup sample also tests positive, the title could be taken from him. You may remember stage 17 as the scene of Landis’ remarkable comeback. Cyclingnews.com says that “some athletes have naturally high levels, and can prove this through a series of tests”…is it possible that Landis was just super amped up from the effort that day?
