Feeling good thanks, Bobster! My sleep patterns are messed up; it's a bit like having jet lag, but physically I was lucky to come out of it with no immediate problems.
Not sure I have properly assimilated it yet. If you can get good weather (out of your control) and good support (in your control) then everything comes together. I wish I hadn't spent 18 hours feeling sick and need to work out what was going on there as I've not had that before in long runs, but as it didn't affect my legs or my energy levels significantly it wasn't too bad.
I think lots and lots of climbing and ascending in my training over the last few months meant that my legs knew what to do, but I'm sure everyone would say that is an obvious thing. You looked pretty strong on the Scafell Massif on Saturday so I'm sure you are there already.
And good luck!
