The term "cross-country" in athletics refers to a long-distance running competition that takes place on natural terrain, such as grass, mud, and hills. Runners traverse a course that can vary in length, often covering distances of 5K, 8K, or 10K. In professional events, both men and women compete separately, showcasing not only stamina and speed but also the ability to navigate changing landscapes. Cross-country races often take place in open fields, parks, or through trails, presenting challenges that differ from track races.
