The decathlon is a combined event in athletics consisting of ten track and field events. The events are held over two consecutive days, and the winners are determined by the combined performance in all events. The decathlon is contested mainly by male athletes, while female athletes typically compete in the heptathlon. The ten events in the decathlon are:

Day 1:

• 100m sprint
• Long jump
• Shot put
• High jump
• 400m

Day 2:

• 110m hurdles
• Discus throw
• Pole vault
• Javelin throw
• 1500m

Each participant receives a score based on their performance in each event, with the winner being the athlete with the highest total score. Decathletes are allowed to commit only one false start across all of the track events, with a second one leading to their disqualification. In the shot, long jump, and javelin events, they are all given three attempts. Should the competition end with two or more athletes tied on points, then the one with the most points in the majority of the events is declared the overall winner.
