Parkour (sometimes abbreviated to PK), or l’art du déplacement (the art of movement) is where participants jump, vault, and climb over obstacles in a fluid manner. It is a non-competitive way to move fluidly despite ones environment. It was developed by the French.

“跑酷”(有時縮寫為PK)，也稱為“移動的藝術”，指參與者用跳躍、跨越或者攀爬等一系列流暢的動作通過障礙物的一種運動。這是用一種非競技性的方式在現有環境中自由移動的運動，是由法國人發明的。

The object of parkour is to get from one place to another using only the human body and the objects in the environment. The obstacles can be anything in one’s environment, but parkour is often seen practiced in urban areas because of the many suitable public structures available such as buildings and rails.

“跑酷”的目標是不借助任何儀器，僅憑借人體和現有環境中的物體從一個地點到達另一個地點。所在環境中的任何物體都可以成為障礙物，不過“跑酷”運動經常會在城區內進行，因為建筑物和軌道等公共設施都是很適合的障礙物。

The term freerunning is sometimes used interchangeably with parkour. While freerunning is more to do with expressing yourself within your environment, parkour is aiming to get from A to B the fastest.

有時，“跑酷”也用freerunning來表示。但其實二者有所不同，freerunning(自由奔跑)強調的是在環境中表達和展現自我，而“跑酷”強調的是用最快的速度從A處到達B處。
