response: Do you know if he does variants of cross-country skiing ? Those are adapted to unimproved terrains and to groomed courses as well
original_response: That's awesome. My favorite form of skiing is cross-country skiing. I love the mountainous terrain as well as groomed courses. You experience a bizarre rush going down a mountain/hill!
history: My brother is a professional skier. Oh wow, really? Skiing can be a means of transport, a recreational activity, or a competitive winter sport. Which one does you brother do? He does it as a competitive winter sport.
knowledge: Variants of cross-country skiing are adapted to a range of terrain which spans unimproved, sometimes mountainous terrain to groomed courses that are specifically designed for the sport.
