Parkour is generally viewed as an acrobatic means of getting from one point to another in the most efficient and direct manner possible. Freerunning is, on the surface, nearly identical to parkour, except additional moves can be added for purely aesthetic flair, such as spins and flips.

Parkour and freerunning also typically differ in that parkour is meant to be free from competition, while freerunning can be performed competitively in a way more similar to a sport.

Bottom line: just ask to David Belle or Sébastien Foucan…
