That 13/14 Feb weekend is going to be busy. We'll be up there as well.
Adnan, the recce was good. It took me 3:11 to reach Cutthroat Bridge and another 2:17 to get back to Edale. I don't recommend taking the A57 from Cutthroat Bridge to Ladybower on foot because there's no runnable verge so you have to stumble on dead undergrowth, which crinkles and crumples with plastic, hidden or not. The litter is horrendous.
Amazingly enough it's the first time I've ever been up on Stanage Edge to Moscar and seen all those abandoned mill stones. Look out for the one facing you with the face drawn on.
