Believe it or not, the number of calories expended while running depends mostly
on your weight and how far you ran. The energy to lift your body off the ground
and wind resistance consume only a small amount of energy.
Other factors such as inclines also affect how many calories you burn. Since they
are harder to measure than distance and weight, these other factors are not used.
Therefore, this calculator assumes that you're running on a flat surface with little
or no wind resistance.
Enter the distance of your run and your weight to calculate the number of calories expended.
