The headline moment came at Cheltenham on 15 March 2024, when Majborough won a Class 1 race — one of the top races in Britain — on the sport's most famous stage. It was also his first career victory, which makes it all the more striking. Plenty of horses spend years working their way up to that level; Majborough announced himself there on day one of his winning career.
He is trained by Willie Mullins at Muine Bheag in County Carlow, a yard that has sent out 230 winners this season alone. That is an extraordinary number — most trainers would celebrate reaching double figures — and it means Majborough is operating in genuinely elite company every day. His regular partner in the saddle is Mark Walsh, and the two of them have found something that works: four wins from nine races together, a win rate of 44%, or roughly winning nearly one in every two times they team up.
What makes the Mullins-Walsh partnership around Majborough particularly interesting is that it has not always been straightforward. Before a run at Leopardstown in February 2026, Walsh pushed to ride the horse his own way, with cheekpieces fitted, against the various opinions flying around the yard. Mullins admitted afterwards it was "poetry in motion down the back" and that he had worried Majborough might run out of petrol late on — Walsh insisted he had plenty left. The horse won. Mullins called it "more like it" and suggested the real Majborough had finally shown up. That kind of jockey-trainer dynamic, where a rider backs his own instinct and gets it right, is one of the more compelling storylines in the sport.
Leopardstown has become something of a home for him: two wins from four races there, including that February 2026 success. Winning half your races at a track is the kind of record that makes people pay attention when the entries come out. Majborough raced just one day ago and remains very much active, with Cheltenham apparently in mind — and on the evidence of what Walsh can do when given a free hand, that prospect looks genuinely exciting.
