The jumper’s take-off foot must not touch the ground beyond the take-off line, nor may the jumper’s foot take off from outside either end of the take-off board.
The jumper takes off from the board and lands in a pit that is between 2.75-3 meters wide and is filled with soft, damp sand.
Under IAAF rules, jumps are measured from the take-off line to the nearest break in the landing area made by any part of the jumper’s body.
