I like some time to think about just whatever is on my mind and let my mind wander. I find it kind of relaxing.

For me, running is consuming enough that my brain can't really operate at 100%, and it's more like 75%. Sometimes this is wonderful because normally my mind tends to go overboard with stuff, but while running my mind doesn't have the appetite to make things heavy and involved.

Another thing is to just stop focusing so much on your inward thoughts and look all around you. Running is a great way to explore and observe an area because you can pick up way more detail than while driving but you can also cover more area than walking.

It also helps to avoid focusing on whether you're done. A watched pot never boils. Asking yourself "how much distance do I have left?" every 2 minutes is sure to make the run seem like it lasts forever.
