NYCRuns offers $100/$50/$25 prize money for their races now, but one facebook comment from a girl reads:
"One of the things I liked about NYCRUNS is that it DIDN'T offer prize money. It was still fun and challening, but there weren't hundreds of competitive professional runners making it impossible for the rest of us."

Don't hate the player, hate the game, sweetie.
