Part 5: William works with  rider whose horse is having issues knocking down the fence with the water tray. They discuss water trays in depth and William reminds the group to pick their battles. The horse in question does jump water trays well in competition, though he isn't relaxed over them. He's an older more experienced horse, and William feels it's not worth a fight to make him clear one in the lower gaits and creating an issue. The rider canters the fence instead and the gelding clears it. The riders work on turns, William coaching them to have the preparation done in the first half of the turn, and the riding in the second. He assists one rider with her mare who tends not to look where she's going.
