The triple jump, sometimes referred to as the hop, step and jump or the hop, skip and jump, is a track and field event, similar to the long jump. As a group, the two events are referred to as the "horizontal jumps." The competitor runs down the track and performs a hop, a bound and then a jump into the sand pit.
The athlete sprints down a runway to a takeoff mark, from which the triple jump is measured. The takeoff mark is commonly a physical piece of wood or similar material embedded in the runway, or a rectangle painted on the runway surface. In modern championships a strip of plasticine, tape, or modeling clay is attached to the far edge of the board to record athletes overstepping or "scratching" the mark, defined by the trailing edge of the board. These boards are placed at different places on the run way depending on how far the athlete can jump.
