From the book I'm currently reading on Lance Armstrong: 'Nowawdays you hear Tour de France champion Bradley Wiggins say it disappoints him to have to talk about doping because it's a sin of the past and you want to sit him down in front of Sandro, let him know that doping can never be in the past.'
Cycling's 'doping' culture predates Armstrong by many decades. Has it ever been any different? It's debatable whether there has ever been a 'clean' winner of Le Tour....Greg Lemond possibly...Froome?...
