Usain Bolt has stunned the athletics world again by storming to a 200m gold medal at the London 2012 Olympics. In a video of the race (shown below) he can be seen outpacing the field from the start, and although countryman Yohan Blake attempts to keep up there was only one winner from the start.

Yohan Blake claimed the silver in second place for the second time in recent days, but he ran Bolt close with a time of 19.44 seconds.

The race started in a frantic pace with both Bolt and Blake immediately pulling out ahead of the rest of the competitors. As they came into the straight Bolt was clearly out front and threatening to gain an embarrassingly one-sided victory. However, Blake managed to remain just behind Bolt and made sure he pushed him all the way.

However, Bolt's immense power showed in the end and with still 10 meters to go he amazingly eased up over the line, yet still came within a few hundredths of a second from the Olympic record.

Jamaica's Warren Weir came in third to claim the bronze with 19.84 seconds, completing the whitewash of medals for Jamaica.

Bolt becomes the first person ever to defend the 200 meters Olympic title. He has already broken the 100 meter sprint Olympic record on Sunday night in London by running 9.63 seconds, becoming only the second person ever to defend that title, and he went one better than Carl Lewis today by defending his 200 meter title.

Following today's 200M victory he will also be taking part in the 4x100 meter relay event in the coming days and will look to claim a third gold medal of the London 2012 Olympics.
