for my two peneth I reckon on targeting three or four stops as 'long' ones. Get some propor food and water in you and make sure everything is still where it should be. I did that at Dent, Fleet Moss and Cray.
as someone else said it's a false economy to whizz thru in 5 minutes only for the next stage to take 20 minutes longer becuase you're knackered.

enjoy!
