After my run, I stayed to watch the first marathoners cross the finish line. Of all those that went by, one runner stands out in my memory.

He was in his early thirties and ran with a determined look on his face. His 26.2-mile journey was nearly done. Above the constant applause, a woman suddenly shouted, "Go B! Strong finish!" Then there was a little girl's voice, "Go Daddy!"

It took a second to spot them, but when he did, the man's cold seriousness became a warm smile. The crowd reacted with greater applause and cheering. I looked behind me and caught a glimpse of his wife and daughter running to meet him at the finish line.

It's a scene probably repeated at many marathons or events. One that everybody else sees quite often. But it's a moment that struck me. It's a moment I would love to experience one day.
