Interesting re the recces (or lack of). I've seen that refuge hut just once too - on the Adventurehub Northumberland ultra in 2011 in the dark ... agree a lot can be learnt from mountain marathons, they are not always especially comfortable - particularly the overnight aspects and putting back damp kit etc on.
It was also interesting to read of you taking a tent, I know I always prefer my laser over a bivvy bag, despite the xtra weight. I'm usually laughed at on MM for taking my 3/4 thermarest and down bag too - but then I am not the speediest participant!!
It's the management of the cold which has made me waver about having a bash at this - I come from a mountaineering/hillwalking/climbing background and have done plenty of winter mountain days in harsh weather, but my circulation seems not to be improving as I age!! Although, that said, despite my small frame I have managed to keep warm on recent forays into the Cairngorms on some winter climbing days ... hmmm back off to chew the cud on this one.
But whether I do decide to give it a bash at some point, your report was a fine old read
