Turf racing is a type of horse racing that takes place on grass surfaces. This form of racing is popular in many countries, including the United Kingdom and Australia. The grass track can affect the speed and performance of the horses, making it a unique challenge compared to dirt racing. In turf racing, horses compete over various distances, and the condition of the turf can change due to weather and maintenance. Races are often categorized by the quality of the turf and the level of competition, with prestigious events like the Epsom Derby showcasing top thoroughbreds on lush grass.
