I sincerely apologise if this topic has been done to death many times before, but I wonder if people have any varied opinion on the hardest fell race in the UK...

I am talking of 'traditional' one day races, as opposed to ultras or multi day events...

I hear wasdale and jura get offered up as good examples, but what about Nant peris, ennerdale, Buttermere....?

Any others I have missed... Anything elsewhere in the UK such as south Wales, Yorkshire or the Peak District...?

As these are the types of races I aspire to be competitive in, it's an interesting topic for me, if not for anyone else...!
