On October 16, 1999, in a ceremony conducted in the winner's circle at Keeneland Race Course in Lexington, the U.S. Postal Service honored Secretariat with a 33-cent postage stamp bearing his image. In 2005, Secretariat was featured in ESPN Classic's show "Who's No. 1?" in the episode "Greatest Sports Performances". He was the only nonhuman on the list, with his run at Belmont ranking second behind Wilt Chamberlain's 100-point game. On May 2, 2007, Secretariat was inducted into the Kentucky Athletic Hall of Fame, marking the first time an animal received this honor. In 2013, Secretariat was inducted into the Canadian Horse Racing Hall of Fame in honor of his victory in the Canadian International 40 years earlier. Secretariat was also the focus of a 2013 segment of "60 Minutes Sports". In March 2016, Secretariat's Triple Crown victory was rated #13 in the "Sports Illustrated" listing of the 100 Greatest Moments in Sports History.
