I agree. I thought it was a useful illustration of the issues.
Like everyone else I have an opinion on what a Fell Running Championship should test and once upon a time I had some influence on that. Twenty years ago a championship which didn't include Wasdale or Duddon Valley etc wouldn't have been worthy of the name but times change and the task for MRAG is to come up with a formula that today's runners will turn up and support - and then to denote that formula as The Championship.
Purity is fine but it is usually trumped by pragmatism.
