I see Pav is at the Auchope Hut now. I've been looking at his mileage since 11am, about 14 miles. That is approx. 1.8 mph. The snow must really be deep and hard going, at least the exertion will keep him warm the wind chill must be well below freezing.
Crikey, he didn't stop long, he is on his way again! Incredible endurance.
