Borrego (horse) Borrego (horse) Borrego (foaled May 17, 2001 in Kentucky, United States) is an American Thoroughbred racehorse and sire. Borrego was bred to sell by a partnership Jon Kelly, Ralls and Foster LLC, Brad Scott and C. Beau Greeley. The partnership twice bought Borrego back at auction when bidding did not reach the reserve price set by the partnership. He was campaigned by Lexington-native C. Beau Greely throughout his 20 race career, which included victories in a pair of Grade 1 races and a start in the prestigious Kentucky Derby at Churchill Downs. Borrego's career as a racehorse began in October
Churchill Downs in 1875. His father-in-law, Richard Ten Broeck, was an accomplished horse breeder and trainer, and introduced Clark to horse racing, attending the English Derby at Epsom Downs outside London. Churchill Downs filled a void in Louisville left by the closing of Oakland and Woodlawn, two earlier race courses. The then-rural location was along Louisville and Nashville Railroad tracks, allowing for easy transport of horses. Clark, who preferred longer races to the relatively short ones that had become popular by the 1890s, was running short of funds, and in 1894 sold the track to a syndicate led by William E. Applegate.
