Dual Doncaster Cup winner Sweet William retires after durable career

Sweet William has been retired after a 24-race career that made him one of Britain’s most dependable staying horses and a two-time Doncaster Cup winner. The son of Sea The Stars was partnered in every start by Robert Havlin, a run of continuity that matched the gelding’s consistency on the long-distance scene.

His record at Doncaster defined much of that reputation. Sweet William won all three of his trips to the Yorkshire track, taking the Doncaster Cup in 2024 and 2025 after already establishing himself there as a proven stayer. Doncaster Racecourse describes the Cup, first run in 1766, as the oldest race still held under the official rules of horse racing, which gives his repeat success there unusual weight in a division built on tradition and stamina.

Sweet William’s form stretched well beyond Town Moor. He finished second in the 2023 Sky Bet Ebor at York, beaten only 1/2 length by Absurde, then went on to win the Group Three Henry II Stakes at Sandown in 2024, narrowly denying Caius Chorister. He added another major staying prize at Ascot on May 1, 2026, when he won the Sagaro Stakes in a photo finish. Racing Post said his career yielded seven victories in total.

The retirement was forced by a joint injury. Owner-breeder Philippa Cooper said Sweet William had developed filling in his joints and was found to be one-tenth lame after an ultrasound, leaving retirement as the right call. Cooper also said the horse, who raced for Normandie Stud, was named after her son, giving the decision a personal edge as well as a sporting one.

Havlin, who rode him through all 24 starts, called Sweet William his “favourite horse to ride.” That loyalty mirrored the horse’s own appeal: he kept showing up for the big staying tests, from York’s Ebor to Sandown, Ascot and Doncaster, and gave Britain’s long-distance program a familiar flag-bearer who was easy to trust when the marathon races mattered most.
