I generally thought that free running and parkour were fairly recent crazes that had gathered momentum over the last few years, but if this video is anything to go by it turns out that people have been running up trees and jumping off ledges since the 1930s.
However, it’s unlikely that anyone did anything as drastic as the most dangerous parkour run ever back then.
