Group races

Group races, also known as Pattern races, or Graded races in some jurisdictions, are the highest level of races in Thoroughbred horse racing. They include most of the world's iconic races, such as, in Europe, the Epsom Derby, Irish Derby and Prix de l'Arc de Triomphe, in Australia, the Melbourne Cup and in the United States, the Kentucky Derby and Breeders' Cup races. Victory in these races marks a horse as being particularly talented, if not exceptional, and they are extremely important in determining stud values. They are also sometimes referred to as Black type races, since any horse that has won one of these races is printed in bold type in sales catalogues.
