Race walking is a long-distance athletic event where participants must 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 technique requires a unique style of walking that emphasizes speed and endurance. Competitions can vary in distance, typically ranging from 5 kilometers to 50 kilometers. Race walking is governed by specific rules set by organizations like the International Association of Athletics Federations (IAAF), ensuring fair play and proper technique among athletes.
