Since one pound has the calorie equivalent of 3,500 calories, you would have to walk at 5 mph for five hours and 40 minutes to burn the caloric equivalent of one pound. Even that isn't a reliable marker because the more you weigh, the more calories you burn.

A 120-pound person would burn less calories in the same amount of time, walking at the same speed, as a 200-pound person. Use the American Council on Exercise's physical activity calorie calculator for your exact weight.

125-Pound Person

A 125-pound person burns 85 calories walking 2 mph for 45 minutes and 140 calories walking 3 mph. A faster pace of 4 mph burns 212 calories.

150-Pound Person

A 150-pound person burns 102 calories walking 2 mph for 45 minutes and 168 calories walking 3 mph. A faster pace of 4 mph burns 255 calories.
