If you're obsessed with running, and are compulsive about getting in a run regardless of other commitments, the weather, or injuries, then you could be considered an addict. You may also have an exercise addiction if you feel guilty when you don't run, or if you work out for a duration, intensity, and frequency that's beyond what's considered normal. Some addicts talk about nothing but running, and even skip out on work just to exercise.
There's nothing wrong with loving and needing to run, both for your physical and emotional well-being, but when running begins to have negative effects on your spirit and your body, then it's time to get some help. Talk to your doctor, a personal trainer, a therapist, or a fellow runner, if these signs sound familiar.
