konecne som pochopil aky je rozdiel medzi parkourom a free runningom
tak ked sa tu najdu aj dalsi, ktori to nevedia tak je to takto:

The easiest way to explain the differences between the two activities is that in parkour you try to get from A to B in the most efficient and natural way which could be exercised in case of a real threat, whereas in free running you might employ movements of greater complexity, solely for their aesthetic value and the challenge of execution.
