Risks are everywhere, and we have nowhere to run. But we can learn to control the danger correctly and minimize it. Therefore, the danger of parkour is quite great, and all Traceur must undergo professional training before taking part in this sport. Professional training means that the most important thing is not to practice, but to understand what the sport is for, not for. Not for a beautiful leap, nor for the grandstanding or eye-catching effect brought by jumping from a height. Parkour is not running around the roof or other stunts that challenge death. People who think so completely misunderstand the essence of parkour.
