Bolt breaks 100m record again

Usain Bolt is super fast. He has broken the 100m world record again, running 9.58 seconds, beating his own record of 9.69 set in Beijing.Actually he smashed it - by more than a tenth of a second and became the first man to break the 100m world record three times in succession. You can see the race here.

It was also the biggest margin since at least the 1960's. The third place getter ran 9.84. That was the world record way back in 1994, so Bolt is bolting ahead of the field.

Wonder if he`ll break the 9.5 second barrier by the end of the year?
