No matter how well-trained your horse is, there is always a possibility that he might spook in a certain moment. So, a good rider should be always prepared for that kind of situation. Watch the following video and see what has happened when a racehorse has spooked during the Laytown Rodeo in 2004.
That horse got scared from something and obviously he got nervous and uncertain. From an onlooker`s point of view that episode seemed amazing! Luckily, the jockey knew how to manage the situation and landed on his feet.
