Free running has taken the world by storm these last few years. It is a form of urban acrobatics in which participants, known as free runners, use the city and rural landscape to perform movements through its structures. It incorporates efficient movements from parkour, adds aesthetic vaults and other acrobatics, such as tricking and street stunts, creating an athletic and aesthetically pleasing way of moving. It is commonly practiced at gymnasiums and in urban areas that are cluttered with obstacles. Some of the world’s biggest cities form an amazing playground and backdrop for some of the free runners in these raw yet energetic photos.
