Hard jumps, soft landing: parkour runners - in French: traceurs know their body and constantly set it new challenges. In the background, music is booming, its beat driving you to the next somersault, the next jump and the next stunt. Teenagers in particular gain a lot from parkour: on the one hand it increases their self-confidence, on the other hand it promotes new friendships and takes them out into the fresh air. It is the same for Manon. The 22-year-old was born in France, just like the sport of parcours. When she came to Essen from Paris three years ago, she immediately made friends through her sport. Today she works as one of the parkours trainers "at Zollverein". Here, ramps, steps, walls, bars covering around 600 square metres form a special kind of playground, right next to the colliery's former coking plant.
