The principal challenge in the decathlon event lies in the diverse range of athletic disciplines. Athletes must demonstrate proficiency in ten varied events: 100m, long jump, shot put, high jump, 400m, 110m hurdles, discus throw, pole vault, javelin throw, and 1500m. This requires athletes to be well-rounded in speed, strength, and endurance. Competing across these events within two days tests not only their physical capabilities but also their mental fortitude and adaptability under pressure.
