But then why aren't all world class sprinters 6-5 then? You would think they'd have the market cornered. I'm not a sprinting expert, but I imagine it's because it's pretty difficult to be that tall and still have the explosiveness to stick with the shorties until the advantage in stride kicks in. Bolt certainly isn't blowing people away in the first 50 meters of his races. i thought you said his height was an advantage, but now you're saying it's a disadvantage. anyhow, if we're all in agreement as to where he gets his explosiveness from, the argument still stands, why isn't the sport inundated with giants? I'm saying that Bolt is unique, which answers both your concerns. He's the rare tall guy(although the 100 is littered with 6-2 and 6-3 winners) with the explosiveness to stay with the pack out of the blocks and then use his stride to pull away. he has explosion because he's working with a really really good chemist. pretty good article. http://www.muscleweek.com/is-usain-bolt-on-steroids i can understand people wanting to see other people run fast but this whole "he's just the best at doing drugs" and being strangely proud of that opinion is [expletive] unbearable. he was a tall, average sprinter that started doing PEDs and changed the game. he's a cheater, and it's his type that causes us to not be able to have nice things. as weird as he is, i don't think carl lewis ever did PEDs. he may be the last great clean champion.
