How fast can a pacer/harness racing horse go?
Like Boo said, they can make around 30 mph. Of course, if I've got a bet on him, the horse will stop for tea halfway round the course.
I think it would depend on the horse.
Sorry, put it in comment. Average speed of a pacer is 30 mphSomebeachsomewhere set a record when he paced at almost 34 mph
