The Agria Blenheim Palace International Horse Trials is delighted to welcome the return of Retraining of Racehorses (RoR) Showing and Dressage this September, with Connolly’s RED MILLS confirmed as sponsor.
Taking place from 17–20 September 2026 in the spectacular grounds of Blenheim Palace, the Horse Trials will once again provide a stage for former racehorses to demonstrate their versatility away from the racecourse.
The RoR programme will feature both showing and dressage, giving riders and their retrained racehorses the opportunity to compete at one of Britain’s most prestigious equestrian events.
The classes will take place on Thursday and Friday, adding another dimension to the opening two days of the Horse Trials and celebrating the adaptability, athleticism and longevity of the Thoroughbred beyond racing.
This year, Connolly’s RED MILLS, a leading name in equine nutrition with a longstanding connection to racing and equestrian sport, will sponsor the RoR Showing and Dressage classes.
Katrina Midgley, Event Director of the Agria Blenheim Palace International Horse Trials, said:
“We’re delighted to welcome RoR Showing and Dressage back to Blenheim this year. It’s incredibly special to be able to showcase these wonderful horses and demonstrate just how versatile they can be beyond their racing careers.
“RoR brings something different to the programme and gives our visitors the opportunity to see former racehorses thriving in another discipline. We’re also thrilled to have Connolly’s RED MILLS supporting the classes this year. Their strong heritage within racing and equestrian sport makes them a fantastic fit, and we’re looking forward to welcoming the competitors to Blenheim in September.”
The return of RoR Showing and Dressage forms part of an action-packed four days at the 2026 Agria Blenheim Palace International Horse Trials, where visitors can enjoy world-class equestrian sport alongside grassroots competition, shopping, demonstrations and entertainment.
At the heart of the sporting programme are Blenheim’s two international classes: the CCI4-L* and the GFS Saddles CCI4-S* 8 & 9 Year Old Class, attracting leading riders and horses to compete against the iconic backdrop of Blenheim Palace.
