As far as I know, it's sand.
A jump is measured from the foul line to the first spot where the athlete touched in the sand pit.
Every jump rope has a different mass depending upon how long it is and what material it's made of. There's no set mass for a jump rope.
From the end of the takeoff board to the point in the pit closest to the board where the jumper touches the sand. If a jumper falls back with their hands, that is the point at which the jump is measured.
the length of how long you can jump
The long jump is measured from the front of the jump board to the closes point in the sand that the jumper touches the sand in a straight line.
just that: the sand pit.

On average the Olympic pit is 24.75m2 on the top.

Two events in athletics use a sandpit: the long jump, and the triple jump.
It varies between different types of ages and skill level. Meaning that a school long jump pit would probably be different then a pit in the Olympics.
The long jump boards are the white lines that line the run way of the pit. These lines are certain lengths away from the edge of the pit. For outdoor the distances from the board to the pit are 4' 8' & 12' in indoor the distances away from the board are 5' & 10'
