Carlos Sastre's name has never been linked to anything suspect that I know of and I'm not accusing him of anything. But my question is this, how did he do it? How did he win The Tour in 2008 when it's now a forgone conclusion that the peloton was indeed doped until at least 2011. How does a clean rider beat a peloton full of cheaters in a GT such as The Tour de France?
