Phenomenon: Le Parkour
Le Parkour (also known simply as Parkour, PK, or free running) is an extreme urban sport, consisting of running and jumping through cities over rooftops, walls, and using other unconventional routes. It has been described as "obstacle-coursing" or "the art of movement".
Le Parkour was invented in 1988 in the Parisian suburb of Lisses by a group of teenagers including David Belle and Sebastien Foucan. They formed a "clan" named Yamakasi (by which they meant "the new samurai") and honed their skills on the neighbourhood's rooftops and fire escapes. Belle and Foucan remain the leading figures of the sport. They have built up their skills so that they are capable of cat-like agility and awesome physical feats.
