Yes but people shouldn't be running much outside their bodies comfort zone so it should always be pretty efficient for getting your thoughts in order and think. It does for me at least but it only did once my spacial awareness was at a level that I could do things like get out of the way of people and increase or decrease my level on the pavement without much thought. It doesn't happen straight away but develops pretty quickly at least for me. I can do about 12km/hr for 1-2 hours without issue but sprints etc make me have to focus completely on the running so they're no good.
