Decathlon, track-and-field event consisting of ten separate contests held on two consecutive days. Points are awarded for each event, and the overall score determines the winner. On the first day of competition, the athletes compete in the 100-meter dash, the long jump, the shot put, the high jump, and the 400-meter run. On the second day, participants attempt the 110-meter hurdle race, the discus throw, the pole vault, the javelin throw and the 1500-meter run.
The second day is always the most demanding because it is the most technical day and the athlete is tired from the first days events. The decathlon does not really start until the second day because any good athlete can do well on the first day but only a decathlete can do well over two days. The second day separates the men from the boys.
The decathlon was first included in the Olympic Games at Stockholm, Sweden, in 1912, when it was won by American athlete James Thorpe.
The entrants receive predetermined points for reaching certain distances, heights, and times in the events.
As you can see from results' pages, lower level there is 6800 points. Actually, most useful would be complete results of competitions.
