Race walking

Race walking is a competitive athletics discipline in which athletes walk under rules requiring continuous ground contact and a straightened supporting leg.

Race walking rules: Competition rules define legal race-walking technique, judging, and penalties. These rules specify the ground-contact and straight-leg requirements that distinguish legal race walking.
20 kilometres race walk: An athletics event in which competitors race walk over a 20-kilometre course. It is a standard international distance and an Olympic race-walking event.
Pedestrianism: A form of competitive walking popular in Britain and the United States from the eighteenth through nineteenth centuries. Race walking developed from earlier organized contests in competitive walking.
Running: A form of locomotion in which each stride includes a period when both feet are off the ground. That flight phase distinguishes running from legal race walking.
Loss of contact: A race-walking infringement in which both feet are visibly off the ground at once. Judges penalize this violation of the continuous-contact requirement.
50 kilometres race walk: A long-distance athletics event contested over a 50-kilometre race-walking course. This demanding event exemplifies race walking’s endurance requirements, though it is no longer Olympic.
Race walking at the 1908 Summer Olympics: The first Olympic race-walking events, held in London in 1908. These events mark race walking’s early inclusion in the modern Olympic programme.
Power walking: A fitness walking style that emphasizes brisk pace and vigorous arm movement without race-walking competition rules. It can resemble race walking but does not require its judged technical criteria.
Bent knee: A race-walking infringement in which the supporting leg is not straightened as required. This is the other defining technical violation judges watch for.
Race walking at the Olympics: The race-walking events contested at the Summer Olympic Games. The Olympics have been a prominent stage for the sport and its changing event formats.
