"Le parcours" was the original word passed down to David Belle from his father Raymond Belle. This was the term Raymond used when speaking to David about the training he had done. The term derives from "parcours du combattant", the classic obstacle course method of military training proposed by Georges Hébert,^[1][2][3] but the term "le parcours" was used by Raymond to encompass all of his training including climbing, jumping, running, balancing, and the other methods he undertook in his personal athletic advancement. One day when David Belle was on a film set he showed his 'Speed Air Man' video to Hubert Koundé, who suggested to change the "c" of "parcours" to a "k" because it was more dynamic and stronger, and to remove the "s" for the same reason. Belle liked the idea and officially changed the name of his discipline to "parkour".

A practitioner of parkour is called a "traceur" [tʁasœʁ], with the feminine form being "traceuse" [tʁasøz]. The original term was simply "tracer" without the 'u' but the word has evolved and now is accepted as having a 'u.' They are nouns derived from the French verb "tracer", which normally means "trace",^[4] or "trail", as in "he escaped without a trace".^[5] When asked recently, David Belle said he prefers not using the 'u' because it is more efficient. This term was the name of a parkour group headed by David Belle which all included Stephane Vigroux.
