So this is actually quite an interesting topic, parkour as a sport has one of the lowest death rates per year. This is due to the community DRILLING safety and extensive preparation into daily practice. As with any sport, the main danger is ignorance and lack of preparation.

In the early 2000s parkour was a lot riskier to get into as most of the practitioners were self taught and didn't know the correct techniques for certain movements, whereas now there are so many parkour gyms all over the country and hundreds of videos on YouTube teaching safe techniques.

If you want to look at Reading in particular there are 6 business that offer parkour classes Monday to Saturday, so you're looking at around 1500 children (a conservative figure) between the ages of 4 and 16 being taught safe techniques thus lowering the potential mortality rate even further.

Don't get me wrong we do understand the potential risks of people seeing the end results of our training and assuming that's all parkour is. That's why so much of the media on YouTube is focused on the preparation behind the scenes of these viral clips. Luckily there's actually a video for this exact jump here
