This is an excerpt from Runners on Running by Richard Elliott.
Then suddenly, a man with an overcoat and felt hat was in the middle of the road shaking his finger at me; he said something to me as I passed and reached out for my hand, catching my glove instead and pulling it off. I did a kind of stutter step, and we all had to jostle around him. I thought he was a nutty spectator, but when I passed I caught a glimpse of a blue and gold BAA ribbon on his lapel. Where had he come from?
Moments later, I heard the scraping noise of leather shoes coming up fast behind me, an alien and alarming sound amid the muted thump-thumping of the rubber running shoes. When a runner hears that kind of noise, it's usually danger—just like hearing a dog's claws on the pavement. Instinctively I jerked my head around quickly and looked squarely into the most vicious face I'd ever seen. A big man, a huge man, with bared teeth was set to pounce, and before I could react he grabbed my shoulder and flung me back screaming, “Get the hell out of my race and give me those numbers!” Then he swiped down my front, trying to rip off my bib number, just as I leapt backward from him. He missed the numbers but I was so surprised and frightened that I slightly wet my pants, and turned to run. But now the man had the back of my shirt and was swiping at the bib number on my back. I was making little cries of aa-uh, aa-uh, not thinking at all, just trying to get away, when I saw tiny brave Arnie bat at him and try to push him away, shouting, “Leave her alone, Jock, I've trained her, she's okay, leave her alone!” And the man screamed, “Stay out of this, Arnie!” and swatted him away like a gnat.
