In reply to danm:
Nice route - Moor Road at Great Longstone is a beautiful road. But up Mam Nick and down Winnats ? I'd do it the other way round, particularly if there is a risk of wet roads, although whilst Winnats is the harder and more iconic climb, I do prefer Mam Nick and tellytubby land. It's just I have nightmares about coming down Winnats.
And if the OP finds himself back at Hathersage with some energy left, can I suggest taking Jaggers/Coggers/Birley Lane up to Stanage (past the campsite) - a glorious golden climb with a great view of the crag to take your mind off the suffering, then a nice fast descent past Higgar and Millstone
