Parkour
While it is true that many people still do not accept the fact that Parkour is a standalone extreme sport, the nature of this physical activity as well as the risks involved in practising it has helped it gain numerous adepts around the world.
To define Parkour, it suffices to say that this non-competitive discipline comprises of moving quickly through an obstacle course, often represented by normal urban settings. In other words, you have to vault, jump, run, climb or roll and basically do anything in your power to reach a pre-established destination in a fast and exciting manner.
