The 400-meter race is a standard track and field event that involves running a single lap around a standard outdoor track. It is classified as a sprint event, requiring both speed and endurance, as athletes must maintain a fast pace throughout the entire distance. Competitors in the 400-meter race start from a staggered position to ensure that each runner covers the same distance. The event is part of major competitions, including the Olympic Games and the World Athletics Championships, and is often seen as one of the most challenging races due to its combination of speed and stamina.
