I think they should just have separate races/classes for people who take performance enhancing drugs. Watching a man sprint 100 metres in 7 seconds? That would be amazing! Ok, he dies at the end from cardiac arrest, but he still got the record right?! Olympic wrestling with people openly on 'roids?! It would be like robot wars! Doping is good! From a spectators point of view anyway It then also opens the door to people with bionics, "welcome to the bionics javelin, Litvinjenko is about to throw! Oh god, he's just killed a woman in morrisons car park half a mile away!"
