response: I am not sure when that event happened, if you ask me about the Nordic World Ski Championships 2011, I can tell you that it started on 23 February and ended 6 March
original_response: They are generally held every other year. So it's a little more frequent than the Olympics.
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. Do you know if he does variants of cross-country skiing ? Those are adapted to unimproved terrains and to groomed courses as well I'm not 100% sure on that, I will ask him. I really enjoy watching the competitions. Do you like to watch the men's cross-country skiing events ? Norway won five golds in those events I haven't seen that one. When was it?
knowledge: The FIS Nordic World Ski Championships 2011 took place from 23 February to 6 March 2011 in Oslo, Norway, at the Holmenkollen National Arena.
