In the last third or quarter of a race I have always responded well to having people yell "Don't be a f***ing pussy!" at me. My coach in undergrad, being a decent human being, couldn't bring himself to do this. Our girls' team, however, loved yelling it. If they raced first they would be doing their warmup, and if they raced second they would be doing their warmdown, so regardless they were all together along the course. Thus, any time I ran past time our ladies' team in the second half of my college cross races, I would have 6-12 intelligent, enlightened, liberal, empowered 18- to 22-year-old women screaming "Don't be a f***ing pussy!" at me. It got me pretty motivated.
