While running, Do all four of a horses feet ever leave the ground at one time?
yes. Here is a picture showing all the steps of a horse’s gallop. There is a moment of suspended motion when all the legs are off the ground at once: http://www.allposters.com/gallery.asp?st… There is also a moment of suspended motion in the canter (if you’re doing a real english canter, not a western lope)… the canter is the same as the gallop except that the 2nd and 3rd legs hit the ground at the same time, so the stride is a little more collected than the gallop stride.
