Race walking is a competitive form of walking that requires athletes to maintain contact with the ground at all times. This means that one foot must be on the ground while the other leg is straightened and not bent at the knee. The sport is governed by strict rules to ensure fairness and proper technique. Typically held on roads or tracks, race walking events can vary in distance, with common lengths being 20 kilometers and 50 kilometers. Athletes train rigorously to develop speed and endurance, making it a unique blend of walking and running techniques.
