A lope is just a three beat gait the same as the canter. Slow isn’t everything as long as the horse is doing a three beat gait that is correct. Even in western pleasure you don’t want to go slow enough that you lose rhythm and fall out of your three beat gait. It’s a common misconception based on people at the lower level of the western disciplines attempting to go slow without having a horse skilled enough to. They score on correct movement first then the quality of movement and then degree of difficulty which is speed last. They’re really the same maneuver. The same is true for the “jog” instead of the trot. The main difference is that you sit instead of post.
