Olympics: Usain Bolt Breaks World Record to Complete Sprint Double With 200m Gold

Usain Bolt has added the 200m title to the 100m gold he won earlier this week, with a world record-breaking run of 19.30sec in the Bird's Nest stadium.

The Jamaican had been threatening Michael Johnson's 12-year-old world record with his times in the heats and tore away from the field to beat the American's mark by 0.02sec.

Bolt broke the 100m record in the final, easing down to the line, but ran hard into a headwind in today's race, dipping for the line despite being well clear of the field.

Churandy Martina of the Netherlands Antilles ran a 19.82 to claim the silver, and Wallace Spearmon came home third. The American, though, was disqualified for running outside his lane, and the bronze went to his countryman Shawn Crawford. Britain's Christian Malcolm finished sixth.
