I'm working on my blog at the moment. It may take a bit of time as loads of photo's.
I'm sure you will do well on your trip so long as the weather is with you.
I didn't drop down to Dufton, didn't see the point, as I'd been there on my first PW and I would have only passed swifly through. I made a sort of beeline after Little Dunn Fell for the top of High Cup Nick. The terrain was difficult and the going slow, so I probably only saved an hour if that.
I also dropped onto the trail that follows the old rail lines from near Slaggyford to Alston, same distance as the PW which runs parrallel. I was just curious what the path would be like.
I lost half an hour after falling asleep when seeking some respite from the blazing sun under the shade of a tree.
I'll post a link when the blog is finished.
