摘要

What led disgraced cyclist floyd Landis, who spent three and a half years after his 2006 Tour de France victory denying he doped, to not only backpedal on his story in May, but accuse onetime teammate Lance Armstrong of using performance-enhancing drugs? Armstrong's associates suggest that Landis launched his campaign against the seven-time Tour winner after Armstrong rejected Landis's efforts to make a comeback.
