Freerunning (or
free running) is an
acrobatic and
athletic discipline founded by
Sébastien Foucan, who wrote a book on the subject. Foucan started what he termed "freerunning" in 2003, which he developed as a more inclusive form of
parkour. Parkour's development from military
obstacle course training gives it and freerunning some aspects of a non-combative
martial art.
