There are the following difficulties. 1) Since the roadbed has almost no cushioning properties, unless a surface material with good cushioning properties is used, the impact of the roadbed will be transmitted directly to the legs of the racehorse, which will hinder the horse's movements and, in the worst case, cause failures. Injure human horses. 2) Since the roadbed itself does not have water permeability, even if the surface material is water permeable, not only does rainwater collect on the surface of the riding stadium during and after rain, and ground maintenance is very costly.
Due to the mud on the surface of the riding ground, the horse is damaged and the human horse is damaged. 3) Furthermore, in winter, the surface material contains water and freezes, and the competition must be stopped. In order to prevent this freezing, great expense and labor are required for ground maintenance such as overnight haloing and spraying of salts such as calcium chloride.
