Two-time Eclipse winner Monomoy Girl began her racing career in September of her 2-year-old year. After taking her first Breeders’ Cup Distaff as a sophomore, she had roughly a year off from training due to two different setbacks. She ran four times as a 5-year-old, then had a three-month gap in between races. As a six-year-old, she ran twice before receiving additional time off.

Consistently given time off throughout her extremely successful career, along with light training during the winters, helped to preserve her and allowed her to develop and blossom over time. While this business has its ups and downs it does prove patience is a virtue. Monomoy Girl earned just over $4.77 million in purse money throughout her career of 17 starts.


The prudent decision was made to retire the seven-time Grade 1 winner by the MyRacehorse team, along with our partners, Spendthrift Farm, and trainer Brad Cox. At the time of her retirement, she ranked as the fifth highest-earning dirt female of all time, joining an illustrious list that includes Midnight Bisou, Zenyatta, Beholder and Royal Delta.

MyRacehorse was thrilled to be able to offer shares through a lease agreement with Spendthrift Farm for this brilliant racemare’s 2021 racing campaign. Spendthrift Farm acquired Monomoy Girl at the Fasig-Tipton Kentucky Fall Selected Mixed Sale, one day after she won the Breeders’ Cup Distaff for the second time in three years. The daughter of Tapizar made history in the sales ring with her $9.5-million purchase price as it tied her for second all time among racing or broodmare prospects sold at public auction in North America.

The late B. Wayne Hughes of Spendthrift was eager to campaign her as a 6-year-old and to share Monomoy Girl with the masses, like Spendthrift did with our Kentucky Derby winner Authentic. Her victory in the G3 Bayakoa Stakes at Oaklawn Park in February of 2021, kicking off her year, was a tremendously exciting moment for the MyRacehorse team to celebrate, along with her 5,045 shareholders. She would race once more that season and was beaten a whisker in the G1 Apple Blossom H. at Oaklawn in April. She was defeated that day by the talented Letruska, who would be named champion older mare for her campaign that year. For her effort in the Apple Blossom, Monomoy Girl earned a Beyer Speed Figure of 102, the second-highest in her career.

Although one door closed for Monomoy Girl, it was just the beginning of an exciting new chapter for the beloved mare, who is now thriving in her broodmare career with Spendthrift in Lexington, KY. In 2023, her first foal was born–a gorgeous colt by Into Mischief.
