The idea of education and increasing knowledge/awareness is a good one but once you start to formalise it - in any way - it cuts across the basic ethos of fell running to my mind.
As has been said, most gain their knowledge and experience out there on the hill and few come to grief, apart from the odd scrape, so I don't think there's any need for any kind of compulsory "training". It would be anathema to most fell runners I'm sure.
However, a resource that people could access if they wanted to - that would be a good thing.
Ideas like this are the kind of thing the FRA could be thinking about but it's more likely to be explored 'independently'.
