In reply to TobyA:
I only meant nip over and start/finish your walk from lower Eskdale rather than up Mosedale 😁, round to Wasdale Head's another half hour each way.
More seriously though, I only go over Wrynose and Hardknott if it's early enough to be before traffic; I get rather frustrated being significantly held up by those who creep along because they have no confidence on those roads.
That's not really the problem because of course they'll never get that confidence if they avoid these roads. It's more that they're ignorant of what should be a standard convention to pull over and let faster traffic go past on routes like this.
Any later and I'd go around, up past Ulpha and over Birker pass to Eskdale. As a bonus on that route you get a great view into upper Eskdale where your walk went.
