Some folks may not realize it but to go into a class and perform for 10 to 20 minutes at peak performance without mistakes takes months of work. Your horse has to be in top physical condition and be able to maintain this peak performance without any bobbles to place high in the class. Grandpa used to tell me a horse has proportionately the same stamina as a man. A man cannot sprint for 15 minutes carrying 50# and your mount can’t perform carrying 300# of rider and gear unless he is in top physical condition.
