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'
As far as I know, it's sand.
