this guy is exceptional!!!!!!!!!!!!!!!!!!!!!!!!! imagine what will happen when he becomes seasoned in the 100m. ppl will say what they want but i can tell you all that the jamaicans who train and live in jamaica dont take dope in order to succeed. they would be too ashamed to go back home.

andrea, new york, u.s.a

Why knock us down if it were a white man who won this race then evryone would be giving him praise, but is it because he is a black man and blacks are suppose to be loosers, come on, you cant keep a good man down for long so all you player haters, give the man a chance if hes a cheat we will know

roxan hill, london , united kingdom

Yay he won lol he flogged every1 altho he could of smashed the record.

Mel Serisiers, Brisbane,

Is there a link online where you can watch this race? I can't find it anywhere...

Ash, Melbourne, Australia

Boo..hoo..hoo...
To all the nay sayers, doubters and haters...I say..GET USED TO IT!!. Usain and Asafa are just showing the world what JAMAICANS can, have always done and will continue to do especially when they remain here, train here with our JAMAICAN coaches and eat JAMAICAN foods.

Marcia, Kingston, Jamaica

sprinting is a very serious sport and Usain has done well to make us Jamaicns and other sprinters around the world proud also other world record holders had used drugs but time will tell the doubters that Asafa and Usain are pure strength , muscles and talent there is no drugs involved. BIG UP USAIN

ARLENE CLARKE, BULL BAY ST. ANDREW, JAMAICA

Both "Nicks" seem to have a hard time hiding their disdain for true athleticism. How about sticking to real ATHLETES gliding around on ice and beating each other into a state of stupor once in a while.

Johnny, NY, USA

Jamaicans take a very dim view of the use of perfornance-enhancing drugs. Just give him credit for a fantastic run and leave it at that unless you know otherwise.

Antoni, Roanoke, USA

Usain's performance is just one expression today of the Jamaican spirit of survival resulting in successful slave rebellion centuries ago - slaves had to run (pun intndd.) for their lives . Query natural selection? : - ). He's clean. Believe it! Our athletes have NEVER had to dope to do well.

Emile, Hampden, Jamaica

One way that records can be improved without drugs is for the athletes to be bigger... and this guy is BIG!

Arni, Brisbane, Australia

Fantastic time - if he can sustain that pace for 200 metres who is there who can beat him? Well done.

Ian, Bristol,

Gregg from Zurich - you're in a minority. So few people believe these days that the top sprinters are clean that the only solution is to allow any performance-enhancing substance the athletes wish to take, and let the chips fall where they may. Lewis, Johnson, Christie, Montgomery, Gatlin

Damian, Reading, UK

awesome run, speed= stride rate x stride length, this guy is very lean not all pumped up on steroids and growth hormone, i dont think the americans will be able to compete now against these two tall jamiacans looking like a one two for jamaica at olympics, udain 1 asafa 2, and gold in the relay in a

david, belfast,

The boy has been a big time sprinter for years, so to just come with "oh he must be doping, because he beat america's best" really is silly of you, they are tested for drugs every race and certainly will be at the olympics. Dont cry because your sprinters cant put up world class times without drugs.

Chad Feanny, Kingston, Jamaica

Are we to believe that he is running FASTER without performance enhancing drugs than the previous "record" holders who were up to their armpits in the banned substances !

sam, Lewisham,

Sprinting is about the human spirit, this is fantastic!!

Carol, London, England

Another Ben Johnson then?

I don't take sprinting seriously at all. It's been up to its eye balls in doping for over 20 years. May the best drugs win!

Simon , London, UK

we are supposed to believe this bloke is running clean .
If everyone was running clean it would be quite close at the finish , Bolt and another runner were way out in front .
It just doesn't add up .
It is laughable people in the sport still think this is genuine.
Flo Jo was clean , yeh right.

Nick Dixon, Sutton Coldfield, England

Nick, the answer to your question is 'yes'.

Gregg, Zurich,

Does anyone still take sprinting seriously these days?
