There is just something indescribable about feeling your muscles respond and pushing into the perfect running pace. It's fabulous. I love when it all comes together - form, air, energy, and efficiency. When all of the thought given to achieving each of those is gone, and the realization occurs. When it's the sun on your face, the blood flowing through happy muscles, the sound of regular, strong breaths. And the thought that 'I could do this forever if I wanted to' streams through your consciousness. Life is made up of a symphony of simple events, and a good run definitely numbers among those for me.
