New World Record 100m Final Olympic Beijing

Video Clip how Usain Bolt from Jamaica set a new world record at 2008 Olympics Beijing 100m final. Usain Bolt set 9.69 sec to break 9.72 sec old record by himself.
By 50 yards he was already finished; he saw that there was no one near him and he pretty much stopped racing. If he had gone full out until the end I bet his time would be much lower.
