 Start doing our intervals, our tempo work, hills. And it's amazing the, what do they call them, endorphins or whatnot that are released when you run. I mean, it's a great feeling when you're in shape. It's the runner's high. You get it and then you feel, you know, for the rest of the day, you just feel like you have a lot of energy. You feel, you know, fresh, sharp. You feel ready to go.
