The show rider has trained hard with her horse to be able to win the show.
When preparing for a big horse show, you have to practise with your horse every day. Sometimes you have to be on the training course very early in the morning. Often it is still quite cold in the riding arena. Then, only a warm riding jacket will help. Every hour on the back of the horse brings rider and horse closer together. Eventually, they are so good that they can even win the tournament. It is all worth the effort.
