Cross-country skiing is about gliding across a snow-covered field on skis in the shortest possible time frame. The course is composed of three equal segments of uphill, level, and downhill fields and athletes must employ classic or skate skiing techniques. The event is not limited to the ski slope like alpine skiing but can be enjoyed wherever the field is covered with snow, allowing participants to appreciate the natural beauty of the track. It has the further advantage that it is liable to less injury risk compared to other skiing events.
