Until reading this book, I thought that the Author, David Walsh had played a bigger part in bringing down the reputation of Lance Armstrong, due to the articles published in the Sunday Times. It is now clear from Mr Walsh's book that Lance Armstrong's actual downfall was instigated by the Federal Investigations carried out in the U.S.A plus the damning evidence provided at a late stage by Armstrong's fellow teammate, Floyd Landis. Mr Walsh descibes how disconsolate he was after thinking that all his years of hard work in investigating Professional Cycling's drug culture were coming to nothing and that in particular , Lance Armstrong was being "let off the hook". However, because of the ongoing investigations, that was not the case and as we all know the disgraced Lance Armstrong did receive his punishment. The unanswered question contained in this book is "what is being done about the criminal activities of the Cycling Team Doctors, Managers and Coaches etc? To me, these people are the criminal instigators of the doping culture, trying to gain unfair and financial advantage. In this book, I found the description of how the use of drugs, particularly the performance drug E.P.O, worked on the human body and how it made experienced cycle race watchers somewhat suspicious, due to the ever increasing speed and the better hill climbing ability of the riders . But five year on, we are seeing exactly the same high level of perfomance by professional bike-riders . So what's changed?
