It's really exciting to be race-walking through 3,000 people. Race-walkers must have at least one foot on the ground at all times and a knee must be straight when one heel hits the ground. Judges placed along the course monitor walkers' techniques and can disqualify competitors if they lift more than one foot. Nearly 70 million Americans walk for exercise and three percent of them race-walk. Typically, walkers compete on 2K outdoor tracks.
Few events occur on roads.
It's an extension of track and field. We're track and field athletes. Walkers have more muscle mass and are more flexible and stronger than runners. Used with permission.
