Cross-country skiing is a popular winter sport that involves skiing over snow-covered terrain using a technique that emphasizes endurance and efficiency. Unlike downhill skiing, where skiers descend slopes, cross-country skiers travel across flat or gently rolling landscapes. This activity can be done on groomed trails or in backcountry areas, making it accessible to a wide range of skill levels. The sport requires specialized equipment, including lightweight skis, poles, and boots designed for gliding on snow. Cross-country skiing is not only a recreational activity but also a competitive sport, with events ranging from sprints to long-distance races in competitions like the Winter Olympics.
