Parkour, aka free running or l'art du déplacement (the art of movement), is beautiful in its simplicity. Traceurs, or those who practice parkour, try to get from point A to point B as quickly, creatively and fluidly as possible. Beyond a good pair of shoes, the sport requires nothing more than an urban environment in which to practice. Modern parkour draws heavily from gymnastics and was founded by David Belle, an ex-firefighter and military officer who starred in the 2004 movie, District 13, a French film featuring a foot chase scene that has a parkour-running Belle escaping from a large band of thugs. Parkour is now popular in cities around the world, and up-and-coming traceurs have taken the sport in some exciting directions.
