and jamaicans are not just winning we have been winning for a long time go check again.

All these Jamacian sprinters are all of a suddne winning. just like at the time of Marion Jones, all the American sprinters were winnig. Suspicious me thinks.

Paula Radcliffe is a train wreck waiting to happen. It will all end in tears in London as well. Please stop wasting tomorrow’s fish and chip paper on her.

Archie "Lefty" Lampton, Coventry, England

"Usain Bolt <> won spreading his arms, thumping his chest and doing the high-step.."... because if he'd gone flat out and sub-9.5 he wouldn't be able in the future break the record again and again like Serge Bubka, milking it at big meetings for millions. Sprinters 'know' what's left in the bag.

Paolo Bagarino, Rome, Ttalia

Robert Evans - what a weird attitude to have. How many more British women (who weren't already racing) were going to do better? Paula is professional athlete and gave it a go. I don't see it as her duty to pull out to allow someone to have a nice trip to China just because she wasn't 100%.

Keith, London, UK

Having sat and applauded with the rest of the crowd in Sydney when Jones "won" her medals I too want to believe in this latest sprinting miracle. But after Johnson, Jones, Joyner - Griffith,Montgomery, Christie, Gatlin, etc. it is awfully hard to do so.

Callan, Liverpool, England

unfortunately a deserving athlete has missed out on competing in the marathon at the olympic games because paula radcliffe insisted on running even though she knew she wasn't fit.

an act of ego and selfishness.

robert Evans, Swansea, United Kingdom

Well, the second fastest man of all time, for the moment.

Michael Johnson ran faster in 1996.

Michael, Nottingham, UK

Excuse me, Kat, but exactly how do you recommend celebrating the discovery you are the fastest man on earth? I remember US relay sprinters openly mocking the Brits in a TV interview for dropping their baton. That's bad sportsmanship. Brilliance buys you the right to savour victory how you want to.

Chris, Worthing, England

By her own admission Paula Radcliffe was not fit enough to compete. Why then was she allowed to? Somewhere back in Britain, there will be another athlete who had trained just as hard as Paula Radcliffe but who missd out on these great Olympics just so that Paula could feed her ego.

Paul Andrews, London, England

Together with a lot of folks, my son and I shouted ' Jiayou!'(Go ,Go!) for her at the point of 38 km. She run heavily and painful, I think she dose did her best. Marathon

For Kat, Columbus USA

Are you on the same same panel of people that also challenged the Womens 100m final result as well ? Saying there had been a false start.

Wow - they really do go for eating sour grapes in the US camp. dont they ? Learn to Lose gracefully !

Dave, Lincoln,

An athlete's first duty and obligation is 'Respect the Body'. Paula Radcliffe in Beijing has shown that her first duty and obligation is to her ego. Don't call her 'brave' for abusing her body when it is crying out for help.

San Ying, Montreal, Canada

I don't believe this was the greatest 100m I've ever seen, simply because I felt Bolt behaved badly as he completed the race. It was poor sportsmanship. I believe it was offensive to athletes and spectators alike, that he "quit" before crossing the line. For me, it overshadowed the performance.

Kat, Columbus, USA

Paula is a great athlete but should she now retire? She seems to feel that tell people often enough she has an injury/fracture/spider bite, when she does not achieve, she can covet sympathy or justify her poor performance. She has a privelidged lifestyle to many of the african runners who do achieve

DR, Bristol, England

Maybe we are all fools , but I also believe I have seen the greatest ever 100m final.
