Usain Bolt has been given a run for his money by a Holloway man who became a 100-metre record holder at the Olympic Stadium during a test event for charity.

Leo Matlock, 24, of Holloway Road, made history in front of 20,000 spectators by running 100m in 12.27 seconds – the fastest time yet recorded at the venue.

He was one of 1,000 fundraisers who took part in races earlier this month organised by Gold Challenge to raise thousands of pounds for charities.

The event also tested the stadium’s facilities ahead of the Games.

Mr Matlock, who is not a professional athlete, stepped in for another runner at the last minute and was shocked to be told by officials that he had made the record books.

“As a born and bred Londoner it’s a fantastic feeling to have run the fastest 100m time at the Olympic Stadium and it has got me really excited for the Olympics coming to town,” he said.

The sports partnership manager, from development charity Right to Play, said he is “reasonably sporty” but his gold win had surprised even him.

He joked about turning athletics into a career but said he wouldn’t enjoy the intense training schedules of professionals.

Though the record is certain to be beaten once London 2012 starts, Leo said he will have “a bunch of great memories” to keep from the day.

He also praised the crowd, saying they had got behind him and all the other runners.

Gold Challenge is backed by the British Olympic Association and aims to inspire people to take on Olympic and Paralympic sports in aid of their chosen charities.

The test event included charity beneficiaries, schoolchildren and celebrities, such as Katie Price, taking part in a number of different sport challenges.

It was hosted by the London Organising Committee for the Olympic and Paralympic Games as a key test event in preparation for London 2012.

Jamaican runner Bolt holds the current 100m world record of 9.58 seconds.
