Racewalking is a competitive form of walking that requires participants to maintain contact with the ground at all times. Athletes must keep one foot on the ground and have a straight leg from the moment of first contact until it is in a vertical position. This technique distinguishes racewalking from regular walking and running. Racewalking events are typically held on roads or tracks, with distances ranging from 3,000 meters to 50 kilometers. It is an Olympic sport, governed by the World Athletics organization, which sets the rules and standards for competitions worldwide.
