Edwin Moses glided fluidly over the track of Oglethorpe University in Atlanta. He had no idea he was being watched by someone who had no idea who he was. The power of his stride captivated the observer who was dazzled. Though the spectator didn’t know the runner, he was awed by what he saw.

The observer was playing tennis with a friend and asked, “Who is that?”

”That’s the Olympic hurdler Edwin Moses,” the friend said. “Allegedly he practices over here because Oglethorpe has the best track surface in the area.”
