Cross-Country (Trail) running involves running over natural terrain. Routes can be of a specified distance and may include surfaces of grass and earth, pass through woodland areas, include hills, flat surfaces and downhills and also sometimes gravel trails. Cross-Country has a rich history of developing a strong cardio-vascular base which can generally not be matched by regular road running. It is also much more rewarding due to the surroundings you are running in, views can often be staggering which leads an easier atmosphere to get some good, strong miles in!
