In a sport where it's hard to make it to the top, many horses are lucky to even run in a graded stakes race. So when a mare throws more than one stakes performing foal, she immediately draws attention to herself.
But while some mares seem to disappear from fans' minds, others etch their way into a spot in fans' hearts.
Because of this, when choosing broodmares to showcase in this article, I decided to open the voting up to racing fans and posed a question on Twitter: Who are your top 10 broodmares of the last 12 years?
The replies were numerous and varied, with only two mares getting more than one vote. Due to this, 13 amazing mares that have proven to be nearly as valuable in the breeding shed as they are on the track are being covered in this slideshow.
So without farther ado, here are 13 mares that immediately come to racing fans' minds when they think of broodmares of the 21st century.
Author's Note: The criteria for who was chosen for this slideshow included if the majority of their winning foals raced after 1999 and how successful their foals have been.
