Grand National Trainers: Records, Dominance and Who to Follow in 2026

If the jockey is the pilot, the trainer is the engineer. Everything that happens in the Grand National — the fitness of the horse, the choice of race, the preparation over fences, the tactical plan — starts in the trainer’s yard months before the field lines up at Aintree. A horse does not arrive at the Grand National by accident. It arrives because a trainer has identified it as a National horse, prepared it accordingly, and navigated the entries, weights and trials to get it there in peak condition. The brains behind the horse make the race possible.

This guide looks at what separates a Grand National trainer from the rest, profiles the leading yards for 2026, and reviews the all-time training records at Aintree — including the extraordinary recent dominance of one yard that has rewritten the record books.

What Makes a Grand National Trainer: Preparation for the Toughest Race

Training a Grand National runner is fundamentally different from preparing a horse for a standard steeplechase. The distance — over four miles — demands a level of stamina that most racehorses never need to develop. The fences require confidence and accuracy. The field size means the horse must be comfortable in traffic, able to settle in a large pack without wasting energy fighting for position.

Grand National trainers begin their preparation months in advance. A typical campaign might start in the autumn, with runs over shorter distances to build fitness and race sharpness, followed by a step up in trip through the winter. Trial races — the Becher Chase over the National fences in December, the Grand National Trial at Haydock in February, the Eider Chase at Newcastle — serve as dress rehearsals, giving trainers a chance to assess their horse’s jumping, stamina and temperament under race conditions.

Schooling over National-style fences is another crucial element. Not all training yards have access to fences that replicate the unique construction of the Aintree obstacles, so some trainers send their horses to courses where they can practise over similar obstacles. The better a horse knows how to tackle the spruce-topped fences before race day, the less likely it is to make the kind of jumping error that can end a race in an instant.

The trainer also makes the key strategic decisions: which jockey to book, what weight to accept, whether to run in a late trial that might result in a rise in the handicap. These are not trivial choices. A trainer who overraces a horse before the National risks it arriving at Aintree stale. One who underraces it risks a lack of fitness. The art is in the calibration — and the best Grand National trainers get it right more often than they get it wrong.

Leading Trainers for the Grand National 2026

The dominant force in modern Grand National training is Willie Mullins, the Irish-based handler who has assembled what many regard as the strongest National Hunt stable in the history of the sport. Mullins’ 2026 Grand National performance was staggering: his runners filled five of the first seven finishing positions — including a clean sweep of the first three — with Nick Rockett winning at 33/1 under his son Patrick. That level of dominance in a 34-runner handicap is almost without precedent and underlined the depth and quality of the Mullins operation.

Mullins’ approach to the Grand National is notable for its volume and versatility. Rather than targeting the race with a single horse, he enters multiple runners with different profiles — some frontrunners, some hold-up horses, some proven stayers and some progressive types having their first crack at the trip. This scattergun strategy maximises his chance of having at least one runner suited to the conditions on the day, and in 2026 it produced a result that rewrote the history of the race.

Among British-based trainers, Lucinda Russell (who trained One For Arthur to win in 2017), Jonjo O’Neill and Nigel Twiston-Davies have strong Grand National pedigrees. Gordon Elliott, another Irish powerhouse, trained Tiger Roll to back-to-back victories in 2018 and 2019 and remains a significant presence in the ante-post market. Dan Skelton and Paul Nicholls are perennial contenders who consistently place runners in the race, even if the headline wins have been harder to come by in the Mullins era.

For bettors, the trainer’s Grand National record is one of the most reliable indicators of a runner’s suitability. A horse trained by a handler with multiple previous National runners — even if none has won — benefits from the accumulated knowledge of how to prepare for the race. A first-time Grand National trainer sending a horse to Aintree is navigating unfamiliar territory, and the odds should reflect that.

All-Time Grand National Trainer Records at Aintree

The all-time Grand National training records are a testament to patience, craft and an understanding of what the race demands.

Ginger McCain holds a special place in Grand National folklore, having trained Red Rum to three victories (1973, 1974, 1977) and later saddled Amberleigh House to win in 2004 — four winners from a yard that was, by elite training standards, modest in scale. McCain’s record demonstrates that the Grand National does not always reward the biggest or wealthiest operation — it rewards the one that knows the race best.

Fred Rimell trained four Grand National winners between 1956 and 1976, a record that stood for decades. Nicky Henderson, the most successful National Hunt trainer by prize money, has a surprisingly thin Grand National record — an illustration of how the race’s unique demands can elude even the most accomplished stables. Jenny Pitman made history as the first female trainer to win the Grand National with Corbiere in 1983, and added a second win with Royal Athlete in 1995 — a record that opened doors for generations of women in the training profession.

Mullins’ recent dominance, however, has shifted the landscape. If he can continue to target the race with the same depth of entries and the same quality of preparation, his total of Grand National winners and placed horses will likely surpass every historical benchmark within a few years. The field reduction to 34 runners has not dampened his advantage — if anything, it has concentrated the quality and made it harder for lesser stables to land a place.

The modern Grand National also requires trainers to adapt to evolving conditions. The course modifications since 2026 — the relocation of Becher’s Brook, the smaller field, the adjusted fence profiles — mean that the preparation playbook is not static. Trainers who cling to old methods may find that the race has moved on. The best Grand National trainers are the ones who study the changes, adjust their approach, and give their horses the best possible preparation for the course as it is now, not as it was a decade ago.

For the 2026 Grand National, the question punters will be asking is straightforward: can anyone beat Mullins? The answer, as with everything at Aintree, is that the race has a habit of humbling the powerful and rewarding the unexpected. But the brains behind the horse remain the single most important factor outside the running rail, and ignoring the trainer’s record is a mistake no serious Grand National bettor should make.
