Known as the Horse Capital of the World, Lexington is where the world's top thoroughbred race horses are bred and trained.  Pristine horse farms in the rolling hills of Bluegrass provide the perfect playgrounds for these beloved creatures.   The most notable of these farms include Calumet Farm, which has produced the most winners of the Triple Crown (2) and Kentucky Derby (8); and Claiborne Farm, home of 2013 Derby winner Orb, and the final resting place of perhaps the sport's greatest racer Secretariat, who stood stud here and sired 600 foals before passing away at age 19 in 1989.
