The Tour de France and the statistics of cheating

The Tour de France, we are told, has finally cleaned up its act and clamped down on the use of performance-enhancing drugs.

But if it has, should we expect today's drug-free riders to be slower than their drug-fuelled forebears? Can statistics tell us whether the Tour de France really is cleaner than it was?

Also in the programme - does when you retire influence when you die?
