I want this to be a turning point. I want this to be an end to it, but I suspect it won't be. There's too much money involved, so, even now, there are laboratories employed by teams to come up with new ways of cheating to stay one step ahead of the testing regimes, which, themselves, depend on honesty to be effective.
I think it's safe to say that Coppi, Anquetil, Merckx, Hinault, Pantani etc all doped in some way or other, and we still revere them as heroes (even if a bit damaged). I wish we'd had a clean sport, but I am convinced it's cleaner than it was ten years ago, and is getting better.
Meanwhile, I have no such confidence in tennis or football or athletics or many other sports which have not been the focus of such close attention on the drugs issue.
