HARD TACK was the sire of Seabiscuit. He was owned by Mrs. Ogden Phipps, and in his first year at stud no one would breed to him. Their reason, his unruliness. He carried the fiery temper of the immortal Hastings, his Great-Grandsire. He won a couple of Major Stakes, but was deemed unsafe.
MAN O’WAR, the grandsire of Seabiscuit was one of the greatest horses to ever set foot on a racetrack. He set records, blew away his competition and took the world by storm. To learn more about Man o’War please visit his site from TBGreats.com at Man o’ War: The Greatest TB Racehorse.
