I know not all sighthound-owners can run as fast as this young man.  I also realize that the sport should definitely be for ALL owners, no matter what their age, physical state, speed, etc.  It was, is, and always will be for all.  That being said, I have always dreamed of an extreme form of  sighthound agility where either the owner does not run the course (so that the hound can run the course at his true top speed), or where the owner/handler is quite a speed-demon himself.  Here is a short film from Japan which falls into the latter category.
