"....
What I saw on these horses was their front legs all beat up by the back legs
hitting the front. ..."
Back in the good ole' days when men were men and horses
worked for a living, you could buy a special harness to teach your buggy horse
the "passing trot*" where the back legs are spread wide, and miss the front
legs. My first endurance horse was a speed quarter horse who taught
himself to do this. When his trot hit ~11 mph you could feel the rear end
drop, the strides per minute go down, and the speed pick up. I measured
from his hoof beats a couple of feet of over stride.
It was extremely comfortable to ride, and apparently
comfortable and efficient for him.
