Something that I just found out, I don't know if any of you know this but they found out why his heart is so big. It seem's that Somethingroyal's sire, PRINCEQUILLO had a big heart and passed it down through his daughters, who in turn passed it down through her sons. I thought this was very intersting because Princequillo was dubbed the Best Distance Horse Ever. Obviously Secretariat's heart was bigger than his siblings, but this makes a very intersting story.
