So the dust has settle somewhat, which leads us to the logical question as to whether this was a dope free tour. How's it hanging: Optimist, pessimist or realist?
What I do know is that the Tour is an uncontrolled environment so that it is quite hard to know what you are watching, even when you are watching it. However, the guys who write this blog "The Science of Sport" also know it. And they are a hell of a lot smarter than me. So have a read and see what you think.
My glass is definitely half full.
