Great Britain's former Commonwealth and European 400 metre champion Iwan Thomas attended the second annual Kickz Olympics run by the Tottenham Hotspur Foundation at the Lea Valley National Athletics Centre.
The 35-year-old, who also won silver at the 1996 Athens Olympic Games, attended to give competitors an inspirational talk before lending a hand in the variety of track and field events on show.
The Foundation bring together their eight different Kickz projects from across north-east London to compete.
Thomas said: "The Kickz Olympics is a great idea. Anything to get kids off the street and doing something proactive gets a thumbs up from me.
"I was also impressed with the standard of competition - there was some real talent on show. But the main thing is that the guys enjoy themselves.
"I've got to admit I am almost jealous that there wasn't anything like this on offer when I was growing up. These young people are being given a once in a lifetime opportunity to compete at a world class venue.
"I have to give a massive thank you to the Tottenham Hotspur Foundation for putting on an event like this. Hopefully all who competed would have enjoyed themselves and look to get involved in athletics at some point in the future."
In April 2006, Tottenham Hotspur was selected as one of three professional football clubs to pilot Kickz , with the main aim being to provide young people with alternatives to a potential involvement with crime and anti-social behaviour within a constructive and safe environment.
The Club piloted the original project on the Ferry Lane housing estate in Tottenham with great success.
In September 2007, Prime Minister Gordon Brown announced the expansion of the Kickz programme as part of a three-year multi-million pound investment from the Football Foundation and Metropolitan Police, along with support from the DCMS via the Premier League's good causes fund and the youth volunteering charity 'v'.
As well as football and a range of other sports, Kickz gives participants the opportunity to take part in music, dance and film-making, as well as offering advice on safe and healthy lifestyles, and workshops on the danger of guns, knives, drugs and alcohol.
