This victory means Bolt now has SIX gold medals in total.

Bolt has won the same three golds at London 2012 and Beijing 2008 - 100m, 200m and 4x100m relay.

He said: "It's a wonderful feeling to end on a high note. It was a great championships, I'm happy, the team came out and gave it their all, I wish we could have gone faster but we leave room for improvement."

Bolt's teammate Yohan Blake joked about their super speediness: "Basically, we are not human... We are from space, I am from Mars."
