I am searching for a single word noun describing someone who practices free-running, obstacle courses or simply parkour.
Other sources I found simply call them "practitioners of [the said technique]" or are not single-worded. In german there is the word "Parkourläufer" which is a trick as it stitches two nouns together, but "parkourrunner" but this sounds clumsy to me.
It does not have to address parkour specificaly, any technical or slang noun describing someone who does similar activities regarding running and jumping over obstacles a lot will suffice. The less specific about the kind of obstacles or courses (e.g. rooftops, cars..) the better.
