The 4x100 meter relay is a track and field event where four runners each sprint a distance of 100 meters. The race begins with the first runner, who starts from a stationary position. After completing their leg, they pass a baton to the next runner within a designated exchange zone. Successful baton exchanges are crucial for a good race time. Each team aims to complete the relay in the shortest time possible, with the fastest teams often competing in major events like the Olympics and World Championships. The event showcases speed, teamwork, and precise timing.
