I have a gelding that is very nice and listens very well but when I take him up a hill or through a ditch he always lopes up the incline. If I hold him back then he will stop and stand still no matter how steep it is but if I don't hold him back he will lope up. I've tried slowing him down but his only speeds are stop and a slow lope that is slower than a walk. Now it doesn't scare me or really bother me except that I believe that I should be the one picking which gait we are in. On flat ground his transitions are beautiful. Any thoughts would be very much appreciated.
