I'm with you in spirit. I walked Coast to Coast about 5 years ago, and my first day took me almost to Ennerdale Bridge. Next morning I took off early and deviated from the Wainwright route to walk over Great Borne to Red Pike and along the ridge. The weather was clear, and the chance was too good to miss. By the time I'd walked over Haystacks I was feeling tired and took a couple of short breaks before dropping down to Rosthwaite.
In retrospect it was a hard second day, but I wouldn't have missed it for anything. I was full of energy next day, so no problems there. I think some people struggle with navigation after they leave Black Sail Hut. Some miss the path up Loft Beck, whilst others are confused in the mist when they reach the flatter ground above Loft Beck. From your posts on this forum you both seem well prepared, and I wish you a happy time.
