Are you saying you average 40 calories a mile?
Not sure how you can figure out that you use 40 calories for a mile. I am no expert but I would assume that if one mile was climbing and your heart rate was at say 160bpm and the next mile you are on flat ground and your heart rate is at 135bpm you would not burn as many calories as you did while climbing the hill. Does that sound reasonable or am I incorrect on this?
