I'm a pretty fit guy, I play soccer competitively for my local team, race motocross, and cycle quite a bit, so I can't nail it down to lack of work in the gym? Or does skiing/boarding just work you differently?
Last Xmas I got two days boarding at Whistler(50cm pow day, woot woot) then took a week off, ate lots of Xmas food and then hit Revelstoke for a few days, then came home and spent the usual week skiing in the French Alps. So I guess Canada was sort of my training. This year though, I'll just be jumping straight into a week in France, so have to be ready to roll!
