I could RO
If you know where to look there’s a couple of bogs on Fountains Fell that could easily be measured in fathoms. And the straight up the wall line climb from Silverdale must do 10 x 10 metre* contour lines in less than a furlong. A truly great place for fell running but possibly one that would be spoilt by other runners going up there
*Apologies I of course mean 0.5 ‘chain’ contour lines
