This is the World’s Best Parkour and Freerunning from 2013. Some guys show off best parkour and freerunning skills. Most of them are very dangerous and risky, and take lots of practice.
Parkour's training methods have inspired a range of other activities, including freerunning. Although their creators define them as separate activities, practitioners and non-practitioners alike often find it difficult to discern the differences between them.
Parkour is a holistic training discipline using movement that developed from military obstacle course training. Parkour can include obstacle courses, running, climbing, swinging, vaulting, jumping, rolling, quadrupedal movement, and the like, depending on what movement is deemed most suitable for the given situation.
Freerunning (or free running) is the art of expressing oneself in his or her environment without limitation of movement. It is a martial discipline founded by Sébastien Foucan, who wrote a book on the subject. Foucan started what he termed "freerunning" in 2003, which he developed as a more inclusive form of parkour, but having more acrobatic-like movements added.
