According to the IAAF Track and Field Facilities Manual 2008, the type of sand for the long jump landing area is
"Washed river sand 0 to 2mm graining, no organic components, max. 5% of weight up to 0.20mm"
Here is the link for the manual:

Two events in athletics use a sandpit: the long jump, and the triple jump.
absolutely not
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.
sandy sand
just that: the sand pit.
a sand pit
There are four judges that are involved in the triple jump event. Two write down the distances, one that measures in the sand, and one that checks if the athlete faulted.
because it was more easier
So they land soflty
um...sand,legs,body etc.
