It's totally unfair to assume that he's doping. Look at how he runs, he just flows gracefully across the track, massive strides means he's a freak of nature, not a cheat!! Drugs in sprinting usually translates into big muscles and a very powerful running style, now go look at Bolt.
I was totally stunned last night, he's the best there's ever been and it couldn't of happened to a nicer guy. He cracks me up, doesn't look like he takes anything seriously, yet is the fastest man to have ever graced this earth. Can he go faster still? Yes I think he will, 22 is very young for a sprinter, his peak is most likely still to come, sub 9.5 should be within reach.
I have to mention Tyson Gay. To run 9.71, a new American record, yet still finish a distant second is just insane. The guy seemed a bit dissheartened in his interview on BBC after the race, appeared happier today though in the medals ceremony.
Bolt is awesome, hope he carries on for years to come.
