Huh, well, I will just construct an aid with wheels, let's call it bike and "run" circles around every marathon runner. Until somebody attaches a motor to that thing, then I have to borrow a race car... You have to somehow say what is allowed and what not, otherwise there is no point at all in competing. And the superhuman achievements of somebody "running really fast" on the basically same base rules that apply to everyone else is exactly what competitive sports is about.
