The most famous such example is Secretariat. His autopsy showed beyond a shadow of a doubt that he had an oversized heart, weighing in at 22 pounds, nearly three times that of the average thoroughbred, and more than three times that of an average non-thoroughbred horse.
It is plain to see that Secretariat had the biggest stride angle of any thoroughbred, which is why he has such a legendary position in horse racing. He was able to cover more ground than his opponents, which led to his stunning victories and phenomenal speed.
