Kenyan runner David Rudisha smashed the world record to win gold in the men's 800m at the London 2012 Olympics this evening.
The 23-year-old led from the start and finished in a time of 1:40.91, breaking his own record of 1 min 41.01 seconds set in Rieti, Italy in 2010.
The amazing performance was the first world record time turned in on the track at the London 2012 Olympics and also ensured David become the first runner from the Kenyan Masai tribe to win an Olympic gold medal.
David finished ahead of 18-year-old Nijel Amos of Botswana and his Kenyan compatriot Timothy Kitum, who finished in bronze.
The victory means, David has gone one better than his father Daniel, who won a silver in the 4x400m relay in Mexico in 1968.
Speaking to the BBC after the race, David said: "Wow! I'm very happy. This is the moment I have been waiting for for a very long time. To come here and to break the world record is something unbelievable.
"I was well-prepared and I had no doubt about winning. Today the weather was beautiful and I decided just to go for it"
