Just watched Justify video that Laurierace linked on the other thread (the thread ‘Justify lame’).
Silly question I may have asked some other time—lead changes, does the horse change on his own, or does the rider ask? In full out racing gallop, is there much difference between “correct” lead and outside lead, for the sake of speed or distance covered, in the straight? I can see it might help with balance and staying tight in the turns, to stay on the “correct” lead, but I honestly don’t know if, when and how the horse changes. I saw it with the video Laurierace linked to because it was only Justify on the video.
