Also the outside "top" of the track is somewhat flat. That is where everyone usually jogs daily so they are jogging on a level surface and not on a slope all the time. That is why the 7 and 8 hole is such a disadvange on a half track. When they say go your horse in the 7 & 8 hole have to come across a hump to get to the inside of the track while the 1 thru 6 can slingshot right across . Some also jog both ways of the track to keep both sides of the horse conditioned the same.
