::Squish7, I think it's clear that Parkour and Freerunning are separate subjects, since that's what the reliable sources say. The issue, as Izno has pointed out again, is simply finding a reasonable number of reliable sources on Freerunning. So far I know of only Sebastien's book, Sebastien's radio interview and Julie Angel's 'Cine parkour' thesis, however there may be some we can salvage from the old Freerunning page. I think the best thing we can do for now is to find more sources on Freerunning. 
 ::There is a lot of media related to Tim Shieff and Daniel Ilabaca so I think we should be able to find sources on their views relatively easily, however I don't consider them to be experts. There is a difference between someone who is good at moving and someone who has a good understanding the discipline as a whole, and they are the former rather than the latter. This difference isn't often appreciated by the media that is focused on spectacle, but we need to be careful when we use their views in an article here. We can use them for sources on the views of freerunners, but we need to word things carefully to avoid confusing facts with opinions. There may be some things we can use from that Fight Science episode, but there is also a lot of nonsense so we need to be careful there too. 
 ::The guidelines are pretty clear that until we can find more sources we can't justify a separate article. So that's the place to concentrate at the moment.
