For a person running at a typical casual runner's pace of 2.5 meters per second (9 km / hr, or 5.6 mph) it can be shown, based on data collected by LG Pugh for the study titled «The influence of wind resistance in running and walking and the mechanical efficiency of work against horizontal or vertical forces,» that the energy cost of
air resistance while running on solid ground is roughly 0.84 calories per kilometer (this is equivalent to approximately an extra 1.2 % calorie burn relative to a runner on a treadmill).
If the runner is on a treadmill he or she does not experience
air resistance while running and therefore burns fewer calories than a runner that is running on solid ground.
Apart from the running calorie burn considerations discussed above, this running calorie burn calculator also takes into consideration the absence or presence of
air resistance while running, based on whether or not the runner is on a treadmill (i.e. no air resistance to overcome) or solid ground (i.e. air resistance must be overcome).

air, every stroke and kick you make has more
resistance than, for example, jogging.

Note that the Model S won over the Prius because
while they had the same drag area, the Tesla had a lower coefficient of drag and a larger frontal area, so it did better starting from a disadvantaged position (smaller frontal areas offer less
resistance to incoming
air, all else being equal).
