The heptathlon is a combined event in track and field athletics that consists of seven different disciplines. It is typically held over two days and includes the following events: 100-meter hurdles, high jump, shot put, 200 meters, long jump, javelin throw, and 800 meters. Athletes earn points based on their performance in each event, and the competitor with the highest total score at the end wins. This event is primarily contested by women in international competitions, such as the Olympic Games and the IAAF World Championships. The heptathlon tests a wide range of athletic skills, including speed, strength, and endurance, making it a challenging and exciting competition.
