Usain Bolt, the Jamaican sprinter, has set his second world record of 19.19 seconds in 200m in Berlin at the IAAF World Track and Field Championships on August 20.

Below is the 200m video and he will celebrate his 23rd birthday on August 21.

I can definitely say I didn't expect that because I was a little bit tired. I said let’s try because people are really looking out for this, I said it won’t hurt to try. So I tried really hard and now I’m really tired, he said after the race.
