Completing the finest week of sprinting in the history of mankind, Bolt added the 200m title and World record to his 100m title and World record by taking the half lap event in 19.30 seconds.

With his 9.69 world record in the 100m on Saturday, the Jamaican became the first man in Olympic history to break both records at the same Olympic Games.

The runs eclipsed his own 9.72 previous 100m best and the 19.32 mark set by Johnson at the 1996 Olympic Games in Atlanta.

But unlike his record dash in the 100, where he spent the latter part of the race looking side-to-side, raising his arms and thumping his chest, Bolt powered through the line with nearly 90,000 people cheering him on to 19.30 seconds.

Speaking with reporters a few hours before the race, Johnson said, “I don’t think that he’ll break it tonight. But it wouldn’t be a shock. Nothing he’ll do would shock me.”

For Bolt, his dream came true. “I’m shock, I am still shock. I have been aspiring to the world record for so long,” he added.

“I work so hard to become the champion and I will work harder to stay on top,” he added.

In the wake of Bolt left Churandy Martina and American Wallace Spearmon, but both were disqualified, which elevated the latter’s teammates, defending champion Shawn Crawford (19.96) and Walter Dix (19.98).

Bolt described the race. “I got out good, ran the corner as had as possible and when I entered the straight, I told myself to ‘keep it up, don’t die on me now,”
