In recent times, high-speed cameras have replaced the plasticine at elite competitions (like Diamond League meetings). An official (similar to a referee) will also watch the jump and make the determination. A layer of plasticine is placed immediately after the board to detect this occurrence. If the competitor starts the leap with any part of the foot past the foul line, the jump is declared a foul and no distance is recorded. Rules An indicator of wind direction and a device for measuring wind speed (here +2.6 m/s) along a run-up trackĪt the elite level, competitors run down a runway (usually coated with the same rubberized surface as running tracks, crumb rubber or vulcanized rubber, known generally as an all-weather track) and jump as far as they can from a wooden or synthetic board, 20 centimetres or 8 inches wide, that is built flush with the runway, into a pit filled with soft damp sand. This event has a history in the ancient Olympic Games and has been a modern Olympic event for men since the first Olympics in 1896 and for women since 1948. Along with the triple jump, the two events that measure jumping for distance as a group are referred to as the "horizontal jumps". The long jump is a track and field event in which athletes combine speed, strength and agility in an attempt to leap as far as possible from a takeoff point.
