I ran the length of Scout Scar which is a limestone ridge to the west of Kendal. It's a great, airy ridge, with views southward to the sea at Morecambe Bay and northward to the Lakeland hills. Underfoot it is quite tricky because it is composed of knobbly limestone. Barely any footstep falls on the flat. Not a place to run if you have weak ankles. And where it is muddy it is that soapy, slippy mud you get in limestone areas.
The part of the ridge I did was 2.17 miles long, giving me a nice 4.34 mile round trip which took 42 mins. So, roughly 10 minute miling, which is OK at my state of fitness. What I failed to realise as I set off was that the whole ridge slopes down gently southwards towards the sea. So the outward leg felt fine; but coming back was always tending uphill. That's why it felt so hard.
Still, I wheezed my way through. In the bright sunshine and cold wind it was one of those runs that restores your faith in this essentially daft activity that we all enjoy. (Or should that be 'enjoy').
