David Belle
A practitioner of parkour is called a "traceur", with the feminine form being "traceuse". They are nouns derived from the French verb "", which normally means "to trace", as in "tracing a path", in reference to drawing. The verb "tracer" used familiarly means: "to hurry up". The term "traceur" was originally the name of a parkour group headed by David Belle which included Sébastien Foucan and Stéphane Vigroux.
