Lance Armstrong doping evidence published by Usada

Cycling legend Lance Armstrong's team ran "the most sophisticated, professionalised and successful doping programme the sport has ever seen" according to a report by the United States Anti-Doping Agency.

In its report, Usada said Armstrong, 41, "engaged in serial cheating" associated with doping.

He has always denied doping allegations but has not contested Usada's charges.
