The decathlon is a combined event in athletics consisting of ten track and field events. The word decathlon comes from the Greek words \“deka\“ meaning ten and \“athlon\“ meaning contest. This challenging competition is typically contested over two consecutive days and requires athletes to demonstrate versatility in running, jumping, and throwing disciplines. 
On the first day of decathlon competition, athletes participate in five events: 100 meters, long jump, shot put, high jump, and 400 meters. The second day features the remaining five events: 110 meters hurdles, discus throw, pole vault, javelin throw, and 1500 meters. Each event is scored according to established tables, and the athlete with the highest total points across all ten events is declared the winner.
The decathlon has been a staple of modern Olympic Games since 1912 for men\“s competition. It is often considered the ultimate test of an athlete\“s all-around ability in track and field. Famous decathletes like Daley Thompson, Bruce Jenner （now Caitlyn Jenner）, and Ashton Eaton have achieved legendary status in the sport through their decathlon performances. |
