This progression can take hours, days, and even years depending on the path you choose, your natural ability, and several other factors. The important thing is to continue progressing no matter how slowly. This method is the essence of Parkour, and will lay the foundation to understand it.
Remember that while large gatherings have the potential to be an extension of the smaller training and discovery sessions, too often they devolve into a roaming herd that quickly grazes over obstacles while looking for the next big trick. Understanding Parkour through self discovery is the sure way to avoid falling victim to this personal experience, making a traceur and his Parkour unique.
As Parkour gets more popular, an increasing number of people are trying to cash in as coaches. Be wary of anyone who doesn’t offer their services for free, at least part of the time. A coach who is still connected to the community, through free outdoor training sessions , is a good bet.
