Parkour

“Free running” is the English language equivalent for the French sport of parkour. The origin of parkour comes from the French Army obstacle course, l’parcours combatant, used for training. Practitioners of parkour, or traceurs, use agility and strength to cross an urban landscape using acrobatics. The sport requires as much discipline as a martial art, as much strength as mountain climbing, and as much endurance as long-distance running.
A traceur might begin on the roof of a 5-story building then drop to a fire escape two floors below. He might then flip over the edge of the railing, hang, and drop to the railing of the level below. There, he might catch himself on that railing, hang, and then drop two more stories to the street. The idea behind this dangerous maneuver is that through a system of three drops, the traceur has reached the street in a matter of seconds. The more traditional method of finding a set of stairs, or waiting on an elevator, might take minutes.
Over the past decade, parkour has increased in popularity and has gained a cult following. Action movies have noticed the sport, and some directors include chases between traceurs through crowded city streets. Training academies report more young people are signing up to study the art every season. YouTube and other upload sites contain hundreds of links to videos from amateur traceurs. It may not be too long before the world gets its first view of parkour at the Olympic Games.
