The decathlon is a combined event in athletics consisting of 10 track and field events. The word "decathlon" was formed, in analogy to the word "pentathlon", from Greek δέκα and ἄθλος. Events are held over two consecutive days and the winners are determined by the combined performance in all. Performance is judged on a points system in each event, not by the position achieved. The decathlon is contested mainly by male athletes, while female athletes typically compete in the heptathlon.
The 1968 Summer Olympics, officially known as the Games of the XIX Olympiad and officially branded as Mexico 1968, were an international multi-sport event held from 12 to 27 October 1968 in Mexico City, Mexico. These were the first Olympic Games to be staged in Latin America and the first to be staged in a Spanish-speaking country. They were also the first Games to use an all-weather (smooth) track for track and field events instead of the traditional cinder track, as well as the first example of the Olympics exclusively using electronic timekeeping equipment.
