On August 16th, 26 youngsters from 18 countries gathered at London's Trafalgar Square to compete in the World Freerunning competition, a sport that involves gymnastic moves like handstands and back-flips, all performed in an everyday urban environment.

Freerunning originated 20-years ago in Paris, France where it is known as Le Parkour. Since then, it has evolved into an organized sport, made even more official by these kind of events.

The event was won by last year's runner-up, 21-year-old Tim "Livewire" Shieff, a British resident who took up the sport five years ago. Victor "Showtime" Lopez from the USA and Jason Paul from Germany came in second and third respectively. To learn more about this sport and the athletes, check out
