4 miles with my son

4 miles at 5:30AM with my son. No music. Full moon. Trains. Crickets. Dogs. The clicking rhythm of 4 feet on pavement. He is young, light of foot and very quiet when he runs. I, on the other hand, am not so young, clomp along and can't figure out how to quiet the heavy breathing and occasional gutteral groan. Regardless, he will one day remember doing some early morning training runs with his dad.
