A long jump in track and field is a jumping event where athletes try to jump as far as possible from a takeoff point. The jump is performed by sprinting down a runway and then leaping into a sandpit, with the distance measured from the takeoff point to the closest mark made in the sand by any part of the athlete's body.

Meter running is the national sport but other sports are played there. The other sports are table tennis, cricket, soccer, surfing, scuba diving, dominoes, and volleyball. They also have bobsledding which made a worldwide hit movie Cool Runnings
