I'm struggling to understand the point. We have hashers, as BBH says they don't all drink during the run although on some runs some might. The OP says the focus is on a good quality run but the video link seems to suggest people of all standards are joining in. And who is to judge what a good quaality run is? And if you mean fast or long or simply hard run, aren't you going to want to stretch and possibly even shower afterwards? Can you do that in many pubs? Sounds more like a normal running club to me. Or at least a few of the ones that I know!
