City of Troy Horse – Pedigree, Wins, and Stud Fee Guide

James Freddie Davies • 2026-06-01 • Reviewed by Maya Thompson

City of Troy did what few racehorses manage: he dominated on turf as a juvenile, conquered the Epsom Derby, and then crossed the Atlantic to win the Breeders’ Cup Classic on dirt. By the time he entered the Coolmore stallion barn for the 2025 breeding season, he had established himself as the best racehorse on the planet.

From his debut at the Curragh to his final start at Del Mar, the son of Justify never finished worse than second. His combination of American speed and European stamina, paired with a flawless temperament, made him the kind of horse that commercial breeders dream about. This profile covers everything from his pedigree and race record to his stud fee and future plans.

City of Troy is by Justify, the 2018 US Triple Crown winner whose first crop instantly made him a sought‑after sire. The dam, Together Forever, won the Fillies’ Mile at two and is by the legendary Galileo. This cross — American speed over European stamina — is rare and highly commercial. The female family traces through Green Room and Chain Fern, and has produced Group winners such as Lord Shanakill.

What Is City of Troy’s Race Record and Key Achievements?

Did City of Troy Win the Derby?

Yes. City of Troy won the Epsom Derby (Group 1) in June 2024, defeating a strong field and confirming the promise he had shown as a two‑year‑old. The victory made him the first son of Justify to win a European Classic and cemented his status as the leading colt of his generation.

What Group 1 Races Did City of Troy Win?

Across his career he captured five Group 1s: the Dewhurst Stakes (2023), the Epsom Derby, the Coral Eclipse, the Juddmonte International, and the Breeders’ Cup Classic (all 2024). The Classic win at Del Mar was especially notable because it proved his form could transfer from turf to dirt at the highest level.

How Much Did City of Troy Earn?

Prize money totalled approximately £5,847,372, according to published records. The Breeders’ Cup Classic alone carried a purse of $7 million, and his Derby victory added more than £900,000 to the total.

World Champion Status

City of Troy was named the Longines World’s Best Racehorse of 2024, a title that reflects his dominance across two surfaces and three countries. He is the first horse trained by Aidan O’Brien to hold the global number‑one ranking outright since Giant’s Causeway in 2000.

Has City of Troy Been Retired or Is He Still Racing?

Is City of Troy Racing in 2025?

All available evidence points toward retirement. His final start was the Breeders’ Cup Classic in November 2024, and Coolmore immediately began marketing him as a stallion for the 2025 season. No entries have been made for any 2025 race, and no public statements have suggested a return to training.

Where Does City of Troy Stand at Stud?

Commercial Appeal

The Justify x Galileo cross is unique in the stud book. Justify brings dirt‑oriented speed and a Triple Crown pedigree; Galileo contributes turf class and a proven broodmare line. Breeders can use City of Troy on mares from both the American and European pedigrees, increasing his market scope.

Uncertainty Around First Season

The exact number of mares City of Troy will cover in his first year has not been disclosed. While Coolmore typically books premium stallions to a full book, the final count depends on demand, veterinary checks, and the farm’s internal strategy. His first foals are expected in early 2026.
