I really hate these questions because I don't know the answer. I would really like to have access to some science equipment and we could all get together for the weekend and once and for all answer the question. :-)
I go by the rule - which is no more accurate than any gym equipment, fitness tracker, or electronic device - 100 calories per mile. Some runners burn more, some less. More is burned if it's run fast, a little less is burned if you run slow...but fast to me and fast to you is not the same pace.
sigh - the best we can do is pick the number that seems to work best for us. I don't use my garmin. it always allows me more than 100 calories per mile. With 100 calories per mile I am able to track my calories and lose weight without feeling totally starved.
Sorry i couldn't be more help.
BUT, if ever you have access to a lab. I will volunteer.
