If we treat running more like Formula 1 racing, for instance, the sport is elevated beyond just that of runner vs. runner (or in F1, racer vs. racer). Technology improvements the the highest level allow for technology improvements for the rest of world, beyond the sport. This is one of my favorite aspects of F1 racing... the constant innovation that happens in these vehicles, and how that innovation reverberates through the auto industry in the form of aerodynamics, fuel efficiency, weight:stability improvements, and so on.
