Running spans many forms: short, explosive sprinting; steady long-distance and marathon running; trail running over rough terrain; and interval training that alternates fast and slow bursts. There's also everyday running to catch a bus. Each type stresses the body differently, from raw speed to sustained endurance.

Track events like the 100-metre sprint and 5,000 metres are competitive running, as are road races such as marathons and half-marathons. Cross-country and trail races run over natural ground. In each, athletes compete on speed or endurance, showing running organised as a formal sport rather than casual exercise.
