Thunder Rumble (1989 in New York – January 6, 2015) was an American Thoroughbred racehorse that The Blood-Horse called a "sensation at Saratoga" race course for his performances there in 1992.Bred and raced by Konrad Widmer and his daughter Ursula under their Braeburn Farm banner, Thunder Rumble was trained by Richard O'Connell. As a three-year-old in 1992, Thunder Rumble missed the U.S. Triple Crown series due to a virus. However, the colt had an outstanding year.
