Parkour at its root is traditionally practiced outdoors in a variety of environments. In the U.S. this has led to unique challenges because of a relatively litigious society and U.S. laws around trespassing and health care. This means insurance plays an outsized role in the parkour community in the US compared to our international counterparts. In response, the US parkour community has more gyms than any other nation to avoid suit over injury, trespassing, etc. This has also had a unique impact on how parkour athletes train in the US, allowing for modular possibilities and shaping the competition space, which has mostly been conducted in indoor gyms to date. Parkour, like surfing, skateboarding, and many other action sports is primarily recreational, but has and is developing avenues for competition. However, in its original philosophy parkour is a competition with one’s self, aiming to expand personal limitations.
