As above, many, many thanks to all involved particularly given the 'challenging' conditions - at least we were able to keep warm by moving (although at times it must have appeared to the casual observer that I was moving so slowly as to be actually motionless).
Apologies also for keeping everyone out for so long - the brief euphoria of making the cutoff at Horton was soon replaced by "oh, bugger" when I realised I had to go on!
