I'm still being careful with my knee so I opted not to do the out and back to Middle Fell with Paul and Rod. It seemed like a logical bit to miss out on this route. Instead, I headed across and waited at the base of Haycock - a little bit below where the cloud was when I took this picture.
On the subject of my knee, I got to the end of the walk today without feeling much at all and the day after it was as good as new. So, I reckon what ever was wrong is now behind me. I think I must have twisted it or something without realising it and as a result I had a month or so if niggling pain which was enough to make me think about how far I was walking on the fells.
