Running is possibly as close to a universal sport as you can get. Runners come in all shapes, sizes and ages, and both sexes. They may be ace Olympic stars, orienteers, marathoners, triathletes, ultra-distance runners, club athletes, fun runners or occasional joggers. Some are fitness fanatics for whom running is an end in itself. Others seek through running fitness for other sports. Many run because it is a convenient way of keeping slim and reducing the risk of heart disease. Some enjoy the challenge of racing, some enjoy the camaraderie of running in a friendly group, while others relish the solitude of training alone.
