I was reading 'Joss' last night and came across this.
Keswick - Skiddaw, Scafell, Scafell Pike, Helvellyn - Keswick.
I cant remember the exact figures but it was in the regions of 45 miles with myabe 18,000ft of climbing and he did it in under 9 hours.
Now, i know im a long way off being able to run 45 miles and that much climbing but it tempted to set my sights on having a bass at it in the next decade.
Anyone else done it? Does joss still hold the record...(sorry if theres already a thread on it, couldnt find it)
