When I start my run, I run on Motivation. When that's all gone I run on Determination. Halfway I change to Satisfaction, for having gotten so far, but that usually doesn't last long.
Then I run on Stubbornness for a long time, and the last miles I use all the Adrenline and Annoyances from the day. Those are the miles I run the fastest.
And in spite of the fact that I have used up a lot, I'm all tanked up after my run.
