Founded by Frenchman David Belle, the aim of parkour is to get from one point to another as quickly and as efficiently as possible, making use of any maneuvre needed to get around any obstacles.
Not to be confused with free running, which is something different.
Wikipedia defines the difference as this: “Parkour as a discipline comprises efficiency, whilst free running embodies complete freedom of movement – and often includes many acrobatic manoeuvres.”
Incidentally, the actor who played the terrorist in that chase scene in ‘Casino Royale’, Sébastien Foucan, is also the founder of free running.
Both parkour and free running are extremely cool to watch, as can be seen in the videos.
