Otto is a fairly new poster on Trailspace, but obviously a very experienced skier. 48Km in one day is almost 30 miles. In pretty cold weather, that has to take some real effort. Note that the trip was by both Otto and his wife, so the two of them must be incredibly fit.

His dog is a big border collie-that's who pulls his sled.

The huts look really nice. I've stayed in huts in NZ, but they are pretty rustic compared to the ones in Sweden and Norway.
