Two things to share. 1) The book Your Brain at Work by David Rock does a great job explaining the brain and how to tilt it in your favor, more often. 2) I have solved more problems and had more great ideas 3+ miles into a run than any place else. There's something to be said for thinking less and not forcing the brain into a corner.
Do you run at a high or slow pace? I find myself unable to focus on my audiobooks while running once the pace is high enough. I imagine all I would be thinking of while running without content to distract me would be the number of the miles left of the run.
Mid to slow. I don't do technology of any sort while running. That's the point. It's the chance to disconnect. I don't run for my body. I run for my mind.
