What is running through your mind while you run?

Is there something that you run from? Something that you run to? Is there someone you run from, or maybe someone you run to?

What do you think about when you run? Or do you run to clear your head and not think of anything?

Do you smile when you run? Have you ever cried while you run? Once you hit the "second wind" and you feel like you could run for ever~ do you?

Do you push yourself to run until you cannot physically run anymore? This is a great way to push away the stress of the day and push yourself until nothing else matters.
