Cross country running is a sport in which teams and individuals run a race on open-air courses over natural terrain such as dirt or grass. The course, typically 3–12 kilometres (1.9–7.5 mi) long, may include surfaces of grass and earth, pass through woodlands and open country, and include hills, flat ground and sometimes gravel road and minor obstacles. It is both an individual and a team sport; runners are judged on individual times and teams by a points-scoring method. Both men and women of all ages compete in cross country, which usually takes place during autumn and winter, and can include weather conditions of rain, sleet, snow or hail, and a wide range of temperatures.

A hill is a landform that extends above the surrounding terrain. It often has a distinct summit, and is usually applied to peaks which are above elevation compared to the relative landmass, though not as prominent as mountains.
