> Those who ask the question 'what harm are they doing to themselves?' are often missing the point, Drugs / Alcohol / Running are all ways in which we 'run' from our demons - the question of 'what harm is this doing to me?' is often weighted against alternatives.

Im not sure if Im following… you are suggesting running is bad for you? Analogous to drugs and alcohol?

And maybe it is a coping mechanism for you but I dont think that is typically why people run. I also dont think abusing drugs is usually better than the alternatives. I would suggest you gather more alternatives if it appears that way.
