The Epsom Derby is more than just a test of speed, stamina, and balance—it’s a showcase of the most influential bloodlines in racing history. As one of the crown jewels in the British flat racing calendar, the Derby has long been shaped by stallions whose legacy stretches across generations.
For punters assessing the favourites for the Derby or enthusiasts interested in the breeding behind champions, understanding these pedigrees is key.
After all, in the world of horse race betting, bloodlines often tell the story before the stalls even open.
Here are the most important and recent bloodlines that have dominated Derby history.
Nijinsky
The last horse to win the English Triple Crown, Nijinsky captured the Derby in 1970 and went on to become a major influence at stud. His Derby-winning progeny include Lammtarra, Shahrastani, and Golden Fleece—each of whom left their own marks on the race. Remarkably, Lammtarra’s dam, Snow Bride, also enjoyed Epsom success, being awarded the 1989 Oaks, making this line one of exceptional dual-classic distinction.
Galileo
Few stallions have dominated the Epsom Derby like Galileo, who won the race himself in 2001. His impact at stud has been historic—producing five Derby winners: New Approach, Ruler Of The World, Australia, Anthony Van Dyck, and Serpentine. Notably, Australia was out of Ouija Board, a brilliant Oaks winner, adding further depth to this Derby dynasty. Galileo’s bloodline is now foundational in European breeding, with his sons and daughters continuing to shape the sport.
Mill Reef
Winner of the 1971 Derby, Mill Reef combined speed and elegance, a profile that made him a breeding sensation. At stud, he sired Shirley Heights and Reference Point, both of whom emulated their sire’s Epsom triumph. His influence endures through middle-distance pedigrees, with many of his descendants continuing to excel on the biggest stages.
Sea The Stars
A modern great, Sea The Stars won the Derby in 2009 as part of a glorious three-year-old campaign. His stud career has been equally impressive, with Harzand landing the 2016 Derby and other progeny excelling in Group company. With the added bonus of being a half-brother to Galileo, Sea The Stars has built a bloodline that combines elite genetics with top-class performance.
Shirley Heights
The 1978 Derby winner, Shirley Heights, upheld the Mill Reef legacy by passing on the Derby-winning gene to Slip Anchor, who claimed the 1985 renewal with a dominant front-running display. His line reflects stamina and resilience—key attributes for success over Epsom’s unique course and distance.
Hyperion
A legend from a different era, Hyperion won the Derby and St Leger in 1933 and went on to become one of the most influential sires of the 20th century. Though more distant in today’s pedigrees, Hyperion’s influence still echoes in the deep recesses of modern bloodlines.

From Nijinsky to Galileo and Sea The Stars, the Epsom Derby is a living tapestry of elite bloodlines. Whether you’re following the form or taking a deeper dive into pedigrees, the race’s history shows that greatness is often inherited. And as each new generation of Derby hopefuls emerges, it’s these bloodlines—rich in classic glory—that continue to shape the story of one of the sport’s greatest prizes.
