You mean like people who need to trick themselves into doing it with contrivances such as frequent jabberfests over the minutiae of their runs? 😉 The main thing I often see is that many seem to be drawn in by an otherwise unfulfilled need to be accepted and affirmed and, quite frankly, running is a highly inclusive activity. There is seemingly a whole joiner mentality at work on a certain level, beyond mere fellowship with like minds. If running truly is “nothing but misery, punishment, pain and agony” on a regular basis then one's true talents likely lie elsewhere and not pursuing that path is basic avoidance. Contrast this with Japan, where as a rule joggers do not enter races.
