Athletics and doping

Ben runs a story that Denise Lewis has hired one of the creators of a massive athletic doping programme as her coach. This is a little bit worrying: a) it doesn’t sound like sensible risk management (what if DL part fails a drugs test?) and b) surely the guy shouldn’t be able to practise any more? In some ways it makes sense: the guy is obviously pushing limits the whole time. That’s the way sport is: you have to be continually striving to be better than anyone else has ever been in order to win.
