a stretch with a sand pit a at the end
Two events in athletics use a sandpit: the long jump, and the triple jump.
It is about 0.33 m deep.
The material in a long jump pit is typically a mixture of sand and rubber granules. This combination provides cushioning for the athlete upon landing, helping to reduce impact and potential injuries. The sand/rubber mix also helps to facilitate proper takeoff and landing techniques for long jumpers.
Long jump is measured from the takeoff line to the closest landing point in the sand pit. The distance is measured in meters from the edge of the takeoff board where the athlete's foot leaves the ground to the mark left by the athlete's nearest body part.
A long jump is measured from the take-off point to the nearest point of contact in the landing pit made by any part of the jumper's body. The distance is typically measured in meters or feet.
Runners run down a runway to a board 20 cm wide they must jump from without the planting foot crossing the plane of the board(forward) and land in a sand pit. From the forward edge of the board to the place nearest where the runner landed in the sand pit is the jump distance measured in meters. In the USA this measurement is in meters and/or feet.
