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 (36 inches) for men and 76.2 centimeters (30 inches) for women. The event requires speed, agility, and endurance, as competitors must maintain their pace while clearing obstacles. Runners typically start from a staggered position to ensure a fair race. The hurdles are spaced evenly along the track, with the first hurdle placed 45 meters from the starting line. The event is a key part of major competitions, including the Olympics and World Championships.
