Sure it is sad to have to say but in this era where just about every league or sport has either a problem or at best a few instances of usage one just never knows for sure. With all that being said Usain Bolt is possibly the biggest freak in all of sports. It is one thing with him setting the Olympic and then World Record at 9.69 despite kicking it into cruise control at like the 80M mark.
What he managed to do at the World Championships on Sunday left little doubt that he is the premier athlete not only in track but maybe the world. In a much anticipated match up between himself and American Tyson Gay it was like Gay and the rest of the field were jogging. Bolt shattered the World Record by an astounding .11 seconds leaving everyone in his wake. That is the biggest margin of change since electronic timing in 1968. Most of these records are beaten by 100th of a second not a 10th of a second. The magnitude of that is just ridiculous. There probably won't be another sprinter that will run a sub-9.60 in at least the next 20 years that isn't named Bolt (I will leave the window open for a Bolt offspring). I still think there is room for him to break his own record. He has said in the past that he does not run for records but he thinks that maybe he can get in the 9.4 range.
This just in from The Canadian Press: The IAAF has announced that there were no positive doping cases in the men's 100 metres, the marquee event of the world track and field championships. Steeplechaser Jamal Chatbi of Morocco is the only positive athlete of the championships so far after more than 600 tests were analyzed. -- I am sure that there were a lot of very happy people in the track world that this is the case...just remember you can only test for what you know about. I'm not saying, I'm just saying.
