When measuring total energy used there was a study done on horses
This found there was an optimum pace that used the least calories. It was a steady pace but not the slowest pace which might have been anticipated
Fast pace uses the most energy
Slowest pace uses considerably less
But there is an optimum pace inbetween the two where the least energy is used. This ties in with experience of running where running really slow can feel harder than at a still relaxed but faster pace.

^ This and I am sure it applied to all animals including humans.

re: Conundrum

I can't remember when, but there was a super cool result about a decade ago that showed that women carrying water on their head (this was in a developing nation) had a slow gait that was more efficient in terms of energy use/distance than walking. If I recall correctly, they couldn't use the gait when they were unloaded.

Good summary of EPOC...aka afterburn.

re: Runningart2004

Total Calories Burned = Duration (in minutes) X (MET X 3.5 X weight in kg)/200

Google the MET level for various running intensities. To compare one mile at various speeds make sure the duration equates the speed..,,ie: 10mph is 6:00, 12mph is 5:00, etc.

Anaerobic metabolism is very, very inefficient

No it's not. Popular myth, which stems from the dreadfully unscientific belief that lactate is a waste product, when it is actually the end point of glycolysis and glycogenolysis.

If you're talking strictly about metabolic efficiency, then faster running would be less economical. When you run faster, you will produce more power, which requires the more powerful type IIa and IIx fiber types. These fiber types use more ATP per unit force production than type I. Not that this is a bad thing, but for endurance runners you need to balance this with substrate (fuel) oxidation, heat dissipation, lactate threshold, and biomechanical efficiency (different than metabolic efficiency) to produce a good performance.

You are the guy who argued that fat metabolism was more efficient than carbs and then spent two weeks arguing the exact opposite.

You are a nut job, why should anyone take you seriously?
