Sense: noun/1

Parkour, free-running, and tricking are all movement disciplines, but they differ in purpose and style. Parkour focuses on moving from point A to point B as efficiently as possible — practitioners run, jump, and climb over obstacles but avoid acrobatic flourishes because they waste energy. Free-running, by contrast, treats the urban environment as a stage for creative expression: flips, spins, and stylish landings are part of the art. Tricking is a separate martial-arts-inspired discipline built around kicks, flips, and twists performed on flat ground, not over obstacles. All three require strength, agility, and body control, but only free-running is defined by its connection to city architecture and its emphasis on personal style.

Etymology

The word free-running joins Old English frēo ('not in bondage, unrestrained') with Old English rinnan ('to move swiftly, flow'). The sport sense emerged in the early 2000s from the parkour community, coined to describe a style that valued creative expression over efficient movement. The biology sense developed independently in mid-20th-century chronobiology research, where 'free-running' described a rhythm that ran on its own without being reset by external cues such as daylight.
