A pioneering sports tournament supported by London's boroughs helped uncover eight of Team GB's Olympic Games medal winners – including the double-gold medallist, Mo Farah (pictured), who originally ran for Hounslow LBC. Before he had invented the ‘Mo-bot', of course.

More than 40 representatives of Team GB at the Olympic and Paralympic Games have participated in the London Youth Games, which celebrates its 35th year in 2012. Previous competitors also included cycling gold-medallists Bradley Wiggins, who represented Camden LBC, and Joanna Roswell, who represented Sutton LBC.
