Walking (also called ambulation) is the main form of animal locomotion on land, distinguished from running and crawling. When carried out in shallow waters, it is usually described as wading and when performed over a steeply rising object or an obstacle it becomes scrambling or climbing. The word walk is descended from the Old English wealcan "to roll". Walking is generally distinguished from running in that only one foot at a time leaves contact with the ground; for humans and other bipeds, running begins when both feet are off the ground with each step. (This distinction has the status of a formal requirement in competitive walking events, resulting in disqualification at the Olympic level.) For horses and other quadrupedal species, the running gaits may be numerous, and while walking keep three feet at a time on the ground. wiki  Learning Vacations Walking Tours arranges independent and escorted luxury tours in Ontario, Quebec and Prince Edward Island.
