Not quite. Caloric expenditure is a function of oxygen consumption. Running is less efficient than walking in that it consumes more oxygen than say walking to move the same mass the same distance. On average running burns 30-50% more calories than walking does. Mass also plays a role in the number of calories burnt in a given exercise. That is why men tend to burn more calories on average (around 20%) than women (the 100/hr figure that you shared) A mass of just 15% or so above average would yield the shared results.

Must be why they ask how much you weigh before you begin running. I always wondered. Brilliant.
