What are the dimensions of a long jump pit?

The landing pit used for long jump must be at least 9 meters long and 2.75 meters wide. The same pit is used for the triple jump.

The pit is filled with either pure quartz or washed river sand to ensure that it does not harden when it gets wet. The runway leading up to the pit is the same width as a lane on the track at 1.22 meters, and it should be at least 40 meters long. The takeoff board for the long jump must be at least 1 meter back from the front of the sand. If the pit is being used for the triple jump, the takeoff board is 13 meters back from the pit for men and 11 meters back for women.
