When people think of horse racing, they often picture powerful stallions thundering down the track. But what many may not realize is that female horses—known as mares (adult females) and fillies (young females)—also play a significant and exciting role in the racing world. So, do female horses race? The short and straightforward answer is yes, and they do so at both amateur and professional levels around the world.
This article delves into the history, biology, competition levels, and famous examples of female racehorses, shedding light on the reality and contributions of these incredible athletes in the sport of horse racing.

Understanding the Basics: What Is a Female Racehorse?
Before exploring the details, it’s essential to define the terms used for female horses in racing:
- Filly: A female horse under the age of four.
- Mare: A female horse aged four and older.
Both fillies and mares participate in various types of races. They can race against other female horses in female-only races or compete against male horses in mixed-gender events.
Do Female Horses Race Against Males?
Yes, they certainly can—and they often do. While some races are restricted to fillies or mares, many races are open to both genders. Female horses have proven time and again that they can hold their own and even outperform male horses.
For example:
- Zenyatta, a mare, won 19 out of 20 races and famously defeated male horses in the 2009 Breeders’ Cup Classic.
- Rachel Alexandra, a filly, won the Preakness Stakes in 2009 against a field of male competitors.
- Winx, an Australian mare, won 33 consecutive races, including several against males.
These achievements highlight the fact that gender does not restrict the potential of a racehorse.
Are There Gender-Specific Races?
Yes. Horse racing offers gender-specific races to encourage broader participation and protect younger or less experienced horses. Examples include:
- The Kentucky Oaks – A prestigious race for three-year-old fillies held the day before the Kentucky Derby.
- The Epsom Oaks in the UK – Another high-profile race exclusively for three-year-old fillies.
- The Breeders’ Cup Distaff – A championship race for fillies and mares aged three and up.
These races create opportunities for female horses to compete without the physical advantages often found in mature male horses, such as greater muscle mass or longer strides.
Are There Biological Differences That Affect Performance?
In general, male horses (especially geldings and stallions) may have a slight edge in muscle mass and aggression, which can contribute to a faster pace in races. However, these advantages are often marginal and don’t necessarily determine the outcome of a race.
Interestingly, some trainers believe that fillies and mares can be more focused and easier to train than their male counterparts. Their intelligence and willingness to work can be great assets in training and competition.
The Economics of Racing Female Horses
The economics behind racing also plays a role in whether a filly or mare is entered into long-term racing competition.
Many successful female racehorses are retired early to become broodmares. Breeding a champion mare can be extremely lucrative, especially when paired with a high-quality stallion. For example, Zenyatta’s foals have drawn significant attention and high prices due to her legacy.
Still, many owners choose to race their fillies and mares competitively before moving them into breeding careers, balancing both financial and sporting goals.
Training and Management Considerations
Training female racehorses involves many of the same routines as with males—regular exercise, nutrition, vet checks, and race preparation. However, some trainers note that fillies and mares may be more sensitive during certain times in their reproductive cycles. Mood changes or discomfort might affect their performance, so close observation and customized care are important.
Despite these considerations, the top female trainers and jockeys have found that many female horses are highly consistent performers who thrive on routine and structure.
Female Jockeys and Trainers: A Parallel Path
The question “Do female horses race?” also opens the door to broader discussions about gender in horse racing—not only among the horses but also among the humans involved.
In recent decades, female jockeys and trainers have also begun to gain the recognition they deserve. Jockeys like Rosie Napravnik, Julie Krone, and Hollie Doyle have broken records and shown that success in racing isn’t confined by gender—whether you’re on two legs or four.
Famous Female Racehorses in History
Here are some notable female racehorses who left their mark on the sport:
- Zenyatta (USA): Known for her dramatic come-from-behind wins, she captivated fans worldwide.
- Rachel Alexandra (USA): First filly in 85 years to win the Preakness Stakes.
- Winx (Australia): Unbeaten in 33 consecutive races, including 25 Group 1 wins.
- Black Caviar (Australia): Undefeated in 25 races and celebrated for her extraordinary sprinting ability.
- Goldikova (France): Won the Breeders’ Cup Mile three times.
These mares and fillies are symbols of excellence, courage, and athleticism.
Why Representation Matters
Representation of female horses in the racing world helps to inspire confidence in gender inclusivity—whether you’re a fan, trainer, breeder, or jockey. By acknowledging their success and potential, the sport remains open, competitive, and diverse.
Final Thoughts
So, do female horses race? Absolutely—and they thrive in both female-only and mixed-gender competitions. While physical differences between male and female horses may exist, talent, heart, and strategy often matter more in the outcome of a race.
Female horses have earned their place in the spotlight with numerous wins in prestigious events. With advancements in training, breeding, and veterinary care, their future in racing looks bright.
Frequently Asked Questions (FAQs)
Q1: Can female horses race in the Kentucky Derby?
Yes. Although it’s rare, fillies can compete in the Kentucky Derby. Only a few fillies have ever won, including Genuine Risk (1980), Winning Colors (1988), and Regret (1915).
Q2: Are female horses slower than males?
On average, male horses may have slightly more muscle and speed. However, many female horses have proven to be just as fast or even faster, especially when well-trained and properly managed.
Q3: Why do some female horses retire early?
Successful mares are often retired early for breeding due to their high genetic value. A famous racing record can translate into valuable foals.
Q4: Do female horses race as often as males?
In general, male horses may race more frequently, but female horses also have active racing careers, especially when owners aim to build their racing credentials before breeding.
Q5: Is it harder to train a female racehorse?
Not necessarily. Some trainers find fillies and mares to be more focused and eager to learn, though hormonal cycles can sometimes require extra management.
In conclusion, female horses are not only capable of racing—they are champions in their own right. They have shaped the history of the sport and continue to do so with grace, grit, and unmatched spirit.
