Skiers on cross-country skis in western Norway. Cross-country skiing is a type of skiing in which skiers navigate across snow-covered terrain using their own locomotion rather than ski lifts or other types of help. The sport was originally known as "snow walking" and was popular among Norwegian men who worked in the mountains during winter months. Nowadays, it is also practiced by people who live in towns and cities throughout Norway. A special type of cross-country ski, called "Nordic walking", has become popular in recent years. This type of exercise combines the principles of Nordic walking with those of traditional cross-country skiing. Cross-country skiing is one of the most popular sports in Norway. It is possible to find cross-country skiers of all ages and both sexes can participate in this sport. There are several major competitions held annually where national teams from around the world come to compete. Some of the most important events include the Winter Olympics, the World Championships, and the Biathlon World Cup. In conclusion, cross-country skiing takes place in various parts of Norway including western Norway, where many famous ski resorts such as Lillehammer, Storås, Rødkleiv, and Vassdalen are located.
