Within the first mile of the race, while crossing the Verrazano Narrows Bridge, a runner leapt down from the sidewalk kicking Chamberlain in the left calf. “The kick caused my calf to cramp up,” said Chamberlain. “At mile 4, it hurt so badly, I thought I was going to have to quit. I was so upset. I thought I was going to have to get a DNF (did not finish), early into the marathon.” The cramping let up at about mile 8 and he kept running.
