Sprints or Sprinting, is a form of running at a persons fastest pace. They are usually short running events that are in track and field and athletics. Sprints are normally short distance, and never exceed longer than 400metres. The main sprinting events in any track or field event in the Olympics are the 100, 200 and 400metre. These three events are held during the Summer Olympics and Outdoor World Championships. Professional sprinters begin a race in a crouched position in the starting blocks, where they soon lean forward then burst out of the blocks and gradually move into an upright position as the race progresses forward momentum is gained. To perfect your sprinting ability and technique, it takes alot of time and effort and hard training to earn good track times and to win gold medals in high standard races.
