The 400-meter hurdles is a track and field event that combines sprinting and hurdling. Athletes race around a 400-meter track while jumping over ten hurdles, each set at a height of 91.4 centimeters for men and 76.2 centimeters for women. The race requires speed, agility, and precise timing to clear the hurdles efficiently. Competitors start from a staggered position to ensure a fair race. The event is typically run in a single lap, and the fastest athlete to cross the finish line wins. The 400-meter hurdles is a popular event in major competitions, including the Olympics and World Championships.
