when running...

Could be anything, or could be nothing at all. Sometimes it's nice to let my mind go totally blank. usually that happens on a tough trail run where every foot placement is a challenge so I'm not hitting a rock or a root. Sometimes I just get a song stuck in my head, or go over events that are going on in my life.

I could NOT imagine doing an activity where all I did was think about how much I hated it. Never in a million years.
