Dom DiPietro, age 13, of Helena, Mont., for his question:

WHAT EVENTS ARE IN THE DECATHLON?

The "decathlon" is a two day contest in 10 events to determine an all around track and field champion. Athletes compete in the 100 meter dash, long jump, 16 pound shot put, high jump and the 300 meter run, in that order, on the first day. On the second day they take on the final five events: the 10 meter hurdles, discus throw, pole vault, javelin throw and 1,500 meter run.

The athletes compete against established time and distance standards, instead of against each other. Up to 1,000 points can bE won for each event. The athlete winning the most points in all 10 events wins the decathlon.

The Amateur Athletic Union (AAU) holds an annual decathlon event.

The decathlon became a part of the Olympic Games in 1912.
