The "400 Meters" is a track and field event that involves running a single lap around a standard outdoor track. It is one of the sprint races, requiring both speed and endurance, as athletes must maintain a fast pace for the entire distance. The race is typically run in lanes, with each runner starting from a staggered position to ensure a fair competition. This event is part of major athletic competitions, including the Olympic Games and the World Athletics Championships. The current world record for the men's 400 meters is held by Wayde van Niekerk, while the women's record is held by Marita Koch.
