Per Mile Energy Net Energy Cost CalculationsThe following are the approximate net energy cost calculations for walking and jogging a given distance, eg. 1 mile:Moderate-paced Walking: The net* caloric cost per mile of walking up to 3.5 mph is 0.77 kcal/kg/mile (eg. for a 154 lb person this would be 54 net calories per mile). This formula holds true for most walkers. The gross caloric cost for this same mile is 90-100 kcal.Fast walking: From approximately 3.5 mph to 5 mph of walking (speed walking) the net energy cost is 1.38 kcal/kg/mile (eg. for a 154 lb person this would be 97 net calories per mile). Note that at the very fast walking speeds (>4 mph) the net energy expenditure of walking and running a mile are almost the same.Jogging/running: the net caloric cost per mile is 1.53 kcal/kg/mile (eg. for a 154 lb person this would be 107 net calories per mile).Treadmill walking or running: the caloric cost of walking or running a given speed and grade is generally 10-15% lower than that indicated on the treadmill LED display. The LED displays usually display the gross cost of walking and running. Net caloric cost per mile of running is nearly twice that for walking one mile at moderate pace (Howley & Franks, 1997). This is a very important point for those who intend to prescribe and quantify walking mileage for weight control purposes.

humm, seems like it would be more

Most people burn 70 to 90 calories per hour at rest. That means that if you sit on the couch for ten minutes instead of running a mile, you'll burn just 12 calories instead of 100.
