The current camera rarely screws up by focussing on a near stationary object but it has happened in the past, so I simulated that idea. Positioned myself so horses by the inside rail would be framed by the outside one, focussed on the closest rail and shot away.
Nice use of motion blur. I would give this a very high vote if this were a motion blur or general blur challenge. The background does appear to be slightly OOF however, but the motion blurred horse is the main thing my eye is drawn to.
