In reply to Tyler:
re: training techniques, I believe the uk-based team have been making a lot of use of roller-skis, skikes (off-road roller-skates) and some tyre-dragging up and down the beach. Another revelation was that one can ascend a smooth, grassy hillside on skis and expendable old skins, without needing any snow at all, thus still getting a sport-specific workout. No substitute for the altitude and scale available by training in the Alps though...
