The Most Successful Grand National Trainers

Winning the Grand National once is enough to secure a trainer’s place in racing history. Winning it multiple times turns them into part of Aintree folklore.

The Grand National is unlike any other race in the jumps calendar. It demands stamina, jumping accuracy, patience and often a little luck. Trainers spend months and sometimes years, preparing horses specifically for this one race, knowing that a single mistake can end everything in seconds.

That is why repeat success is so rare.

Only a handful of trainers have truly mastered the Grand National, producing multiple winners across different eras and proving they understand exactly what it takes to win over the famous Aintree fences.

From Victorian legends to modern racing powerhouses, these are the most successful Grand National trainers of all time.

Why Winning the Grand National as a Trainer Is So Difficult

Training a Grand National winner starts long before race day.

Unlike shorter top-level races, the National requires a very specific type of horse. Trainers need runners with enough stamina to cover more than four miles, confidence over fences and the temperament to handle one of the busiest and most unpredictable races in the sport.

Not every talented chaser is suited to Aintree.

Some horses struggle with the unique fences, while others travel strongly for most of the race only to fade in the closing stages. Finding the right profile is the first challenge.

Then comes preparation.

Many trainers build an entire season around the Grand National, carefully choosing prep races, managing handicap marks and making sure their horse arrives fresh but battle-ready in April.

Even then, luck plays a major role. A loose horse, a poor landing at Becher’s Brook, or traffic problems at Canal Turn can ruin even the best-laid plans.

That is why trainers who win the race multiple times are held in such high regard.

George Dockeray – Four Wins

One of the earliest dominant names in Grand National history was George Dockeray, who trained four winners during the race’s early years.

His victories came with Lottery in 1839 and 1840, followed by Gaylad in 1842 and Miss Mowbray in 1852.

Lottery’s success was especially important because he won the first officially recognised Grand National, giving Dockeray a permanent place in racing history.

Training methods were very different in the 1800s, with less structure and far fewer resources than modern yards, but Dockeray’s ability to consistently prepare horses for Aintree’s brutal demands showed exceptional skill.

His four wins remain one of the strongest records in National history.

Fred Rimell – Four Wins

Fred Rimell became one of the defining Grand National trainers of the era, matching Dockeray’s total with four victories.

He first won in 1956 with E.S.B., followed by another success in 1961 with Nicolaus Silver. His third victory came in 1976 with Rag Trade, before he completed the set with Gay Trip in 1979.

Rimell was known for his calm, patient training style and his ability to prepare staying chasers for the biggest tests. He understood that the Grand National wasn't just about speed, but about rhythm, stamina and jumping confidence.

His horses were often well suited to the demands of Aintree and his consistency over two decades proved he had mastered the race.

Few trainers were as respected in the horse racing betting markets when it came to the National.

Ginger McCain – Four Wins

Some trainers become linked to one horse forever and for Ginger McCain, that horse was Red Rum.

McCain trained Red Rum to three Grand National victories in 1973, 1974 and 1977, creating one of the most famous partnerships in sporting history.

But his success didn't stop there.

He returned in 2004 with Amberleigh House to claim a fourth Grand National win, proving his brilliance extended far beyond one horse; even if that horse was Red Rum.

McCain trained from Southport, close to Aintree itself and knew exactly what type of horse was needed for the National. His practical approach and deep understanding of staying chasers made him a specialist in the race.

Even today, his name is almost impossible to separate from Grand National history.

Tom Dreaper – Four Wins

Tom Dreaper was one of Ireland’s greatest jump trainers and another man to reach four Grand National victories.

He won with Prince Regent in 1946, Freebooter in 1950, Early Mist in 1953 and Quare Times in 1955.

Dreaper built a reputation for producing tough, durable staying chasers who thrived in long-distance races. His horses were often disciplined, powerful jumpers, exactly the qualities needed at Aintree.

His influence stretched far beyond the Grand National but his four wins in less than a decade showed just how strong his understanding of the race truly was.

He helped establish Irish-trained runners as serious National contenders.

Willie Mullins – Four Wins

When discussing modern jump racing, few names are bigger than Willie Mullins.

Already one of the most successful trainers in National Hunt history thanks to his dominance at recent Cheltenham Festivals, Mullins added the Grand National to his long list of achievements with Hedgehunter in 2005 and later pulled it off three years running with I Am Maximus in 2024 and 2026 and Nick Rockett in 2025.

Mullins combines elite talent with precise race planning and every National runner from his yard attracts serious attention from punters.

Nigel Twiston-Davies – Two Famous Winners

Nigel Twiston-Davies produced two memorable Grand National winners and became one of the most respected modern trainers for staying handicaps.

He first won in 1998 with Earth Summit, a powerful stayer who handled heavy ground brilliantly. His second success came with Bindaree in 2002, giving him two victories in just five years.

Twiston-Davies has always been known for producing tough, genuine staying horses who perform well in marathon races, making Aintree a natural target.

His record in the National helped cement his place among Britain’s leading jumps trainers.

Lucinda Russell – Back-to-Back Tiger Roll Success

Lucinda Russell entered Grand National history through one of the most popular horses of the modern era, Tiger Roll.

She trained Tiger Roll to victory in both 2018 and 2019, becoming the first trainer since Ginger McCain to prepare back-to-back National winners.

Tiger Roll’s size made some doubt whether he could handle the race but Russell understood exactly how to bring out his best qualities; stamina, jumping precision and relentless determination.

Those two wins elevated both horse and trainer into Grand National folklore.

Her success also highlighted the growing strength of Scottish-trained runners at the highest level.

What Makes a Great Grand National Trainer?

The best Grand National trainers do more than train good horses, they train the right horses.

They understand that Aintree requires a very specific profile. Stamina matters more than flashy speed. Jumping rhythm matters more than raw power. Temperament can matter more than ratings.

Preparation is everything.

Knowing when to run, when to rest and how to keep a horse fresh for April can be the difference between winning and pulling up before the final fence.

The greatest trainers also know how to handle pressure. The Grand National brings attention unlike any other jumps race and keeping both horse and connections calm is part of the job.

The best National trainers are planners first and risk-takers second.

Why Trainer Form Matters for Bettors

When punters study the Grand National, trainer form should never be ignored.

Some trainers target the race every single year, shaping their season around Aintree. Others may simply have a runner who happens to qualify.

That difference matters.

A trainer with a strong National record often understands how to prepare horses specifically for the challenge. Their runners are more likely to be fit, well handicapped and mentally ready for the occasion.

Recent stable form is also important. A yard in strong spring form often carries momentum into the biggest meetings.

Looking at trainer history alongside horse profile and jockey experience gives a much clearer betting picture.

Because in the Grand National, success rarely comes by accident. It is usually planned long before the tapes go up.
