Lady’s Secret this small and dainty grey filly by Secretariat and out of the gray mare Great Lady M., came to be known as the “Iron Lady” and the “Silver Bullet” for her speed and power on the racetrack. Trained by D. Wayne Lukas, she dominated the races she was in, defeating many of the best colts of her time. As a four-year-old, she won ten of her fifteen starts that season, all graded stakes races. She became the first female to win the Whitney Stakes since Gallorette in 1948. Her lifetime earnings equaled $3,021,325, the best of any of Big Red’s progeny at that point. In 1986 she was named Outstanding Older Female Horse and Horse of the Year, a rare honor for a filly. Blood-Horse Magazine ranked her number 76 in its list of the Top 100 U.S. Racehorses of the 20th Century. She was also inducted into the National Museum of Racing Hall of Fame.
