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.

a sand pit
The mark in the sand made by a long jumper is called a "landing mark" or "jump mark." It indicates the point where the jumper's feet first touch the sand after their jump. This mark is used to measure the distance of the jump for scoring purposes.
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.
So they land soflty
because it was more easier
