Young athletes compete in School Games at Olympic Park
Around 1,600 of the country's best young athletes have been taking part in the School Games at London's Olympic Park.
They've been competing in 12 different sports - including athletics, fencing and wheelchair basketball.
The event is also a final chance to test out the Olympic venues before London 2012 begins.
It can be a springboard to further sporting success - Paralympic champion Ellie Simmonds took part as a kid!
The swimmer said: "It was a great experience for me. It definitely set me up for Beijing [Olympics].
"It was the first place I'd been away from home. I was only 11 or so, going to a multisporting event which I'd never had the opportunity to go for."
The annual School Games is the biggest multi-sport event for school-age athletes.
Fencer Daniel Ming said: "The whole set-up of it, the whole atmosphere - it's really unique and it recreates something that you might experience at a world championships or an Olympic event."
