There's nothing stopping anyone from entering any number of races around the country that Chuck runs and wins. You show up and you put up or shut up! I've met Chuck on a number of occasions and he's always been friendly and gracious. He doesn't have an elitist attitude despite his near-elite times. You'd have to ask him yourself what his motivations and goals are but the results speak for themselves. The man runs damn fast and very consistently week in and week out!
