The 100m sprint is a popular track and field event where runners start from starting blocks and aim to reach top speed just past the halfway point. Runners progressively decelerate in the later stages as they work to maintain their top speed for as long as possible. The winner is determined by the first runner whose torso passes over the finish line, with photo finishes used to determine extremely close finishes. The fastest men's and women's times are held by Usain Bolt of Jamaica and Florence Griffith-Joyner of the United States.
