In reply to Solar:
One of the new Vaseline lip salves - don't know about anyone else but my nose streams when it's cold - stops sore noses and lips. The little tins are great but no good once on the move.
Decathlon LED armbands - for the wrists, as turn indicators (about £7/pair)
Shoe covers - the windstopper ones that just do the forefoot.
A pair or two of Bolle Contour glasses - one clear, one smoked. £8/pair.
