When exercising, does the amount of effort determine calories burned or the actual work being done?

Will an athlete who runs for an hour at moderate pace and is not tired at the end burn more calories than an out of shape person who runs for an hour a way shorter distance but is exhausted at the end?
Assuming both have the same weight and such

What I want to know basically is if your body gets stronger will it need less energy to perform the same amount of work?

My highschool physics teacher had a great lesson for this. He had me and my friend go to the bottom of the stairwell and basically race up three flights of stairs as fast as we could. Then he and the rest of the class came strolling up at a relaxing pace while we were panting at the top. (Aside from slight weight differences) We had done the same amount of work and burned the same amount of calories.
