Than what makes a class

Answer
hi i have ran many horses and against all kinds of class races.  the classy horse will always beat the cheaper horse and i am not sure exactly why that happens, but it usually does. they seem to know they are running against a better horse and they try hard to win , but they are just out classed. hope that helps you  thanks ED HESS
