The 2018 Breeders' Cup World Championships was the 35th edition of the premier event of the North American thoroughbred horse racing year. The 14 races, all but one of which were Grade I, took place on November 2 and 3 at Churchill Downs in Louisville, Kentucky. The races were telecast by NBCSN on Friday and early Saturday, and by NBC later on Saturday. The Breeders' Cup is generally regarded as the end of the North American racing season, although a few Grade I events take place in later November and December. The event typically determines champions in many of the Eclipse Award divisions, although it was missing the eventual Horse of the Year, Triple Crown champion Justify, who was retired in July.
