Humans tend to walk at an average pace of about 3.1 miles per hour. At that rate, the average time for a person to walk an hour is 19 minutes and 21 seconds.
Walking speed varies depending on several factors, including the age, height and physical condition of the walker. Competitive race walkers are capable of averaging almost 9 miles per hour, but most people find it difficult to walk at much beyond 4 miles per hour without breaking into a run.
A walking stride is generally defined as an inverted pendulum gait, where the body swings forward over one stiffened leg while the other leg steps forward. The head stays level, and one foot remains in contact with the ground at all times.
