I am standing at a street corner in the predawn blue. A gas station to my right outshines the few remaining stars, and behind me the green-yellow-red rhythm regains its usefulness. We are all waking up.

Ahead, the sidewalk curves into a trail along a river, where I will see deer and rabbits and ducks, and I will keep looking to the right, past the highway to the eastern horizon, and I will be grinning.

Most runs aren’t like this.
