Besides, if raw speed was the only goal, we would probably all be riding bicycles. Just as a runner can jog or sprint, a racewalker can walk at any speed - maintaining any heart rate up to his or her maximum. The prospect of fewer injuries also brings many runners into racewalking, allowing them to extend their fitness programs and competitive careers well into their golden years. Racewalking provides a much better workout for the muscles in the trunk of the body. Good racewalking technique relies more heavily on the muscles in the areas of the hip, waist, and back.
Runners get their speed by using their legs to go airborne during each step.
Racewalkers, however, are bound to the earth and must also rely on the large muscle groups of the torso to develop their speed. Racewalking generally creates a more knowledgeable athlete. But most people find it hard to racewalk without getting help. In the process, most racewalkers become very conscious of their posture, and the position and action of almost every body part. And, finally, there are simply fewer racewalkers.
