Langrenn = Cross country skiing
You're right about the close relationship with nature. Norwegian cities all exist in a close relationship with nature, and it's a big part of being Norwegian. Norwegian children are encouraged to play outside etc, even if the weather is bad ( No such thing as a bad weather, only bad clothing!). Going on walks etc is viewed as very successful if you don't run into other people, haha. It's kind of the point, to get away from people and be close to nature. Loads of Norwegians have cabins close to ski resorts and so on. As soon as easter comes, many Norwegians travel to their cabins.
The "Norwegians are born with skis on their feet" saying is a stereotype. I've seen plenty fall, and I've fallen myself. I got cross country skis when I was very young, and I have no problems with cross country skiing. I think most Norwegians would be comfortable with skis. But when it comes to slalåm and skiing down very big hills , you'll find terrified people like myself. I've only tried slalåm once. It's scary and almost impossible to get up if you fall! The one time I tried slålom was on a "school ski day".
I've often seen 5 year olds zoom past me on skis. Which is a little strange, but not surprising.
I reckon this is a good link:
