Blue Peter: Olympic Low Down

Helen and Barney are in East London to look ahead to the biggest sporting event on earth, the Olympics. We have British Gold Medal hopefuls, including Andy Murray, Dai Green, Phillips Idowu, Shanaze Reade and Beth Tweddle. We see what it's like for the 10,000 athletes, behind the scenes at the Olympic village. Barney finds out what it's like being a photographer at the Games. His stint as a Getty photographer at a test event at the Olympic Velodrome even ended up with one of his photos being used as the main photo on the cover of the Guardian newspaper.
