A while back, I wrote about my favorite gold medal winning performances from past Olympics (Bob Beamon and Dick Fosbury from Mexico City '68 and Olga Korbut at the Munich games in '72) but today's performance by Jamaican sprinter Usain Bolt in the Men's 100m final eclipsed them all.
Bolt didn't just win the race, he dominated it. After 50 metres the outcome was never in doubt, at 85 metres Bolt eased off and cruised over the finish line grandstanding to the crowd for a new world record of 9.69 secs.
It was a truly phenomenal performance. You can watch it here.
