Race-walking is a unique sport that involves walking at a brisk pace without running. Known as a race-walking, the sport involves a competitive race where walkers are required to keep one foot on the ground at all times. Because of its distinct characteristics, race-walking has few synonyms. Some people refer to it as speed walking or power walking. The term fast-walking is also sometimes used to describe this type of activity. Others may refer to it as walking competitively, or walking competitions. While there are a few names to describe competitive walking, race-walking remains the most commonly used term to describe this sport.
