I have watched the reply of this several times today on HRTV. Don't know a lot about TB racing but I am aware there is a "right" and "wrong" lead to be on in the stretch. Well, I watch Little Mike change his lead no less than 4x in the very end of the race every few strides. What would cause that? I believe I've heard that they will get tired running on one and thus will switch but I've never noticed a horse switch with this level of frequency. Can anyone fill me in?
