Jockey and Trainer Stats at Aintree: Patterns That Hold

The yard patterns that don’t break
Ask any serious jumps punter which yards prepare a Grand National horse best and you’ll get the same four or five names, year after year, from different people who haven’t compared notes. That consistency isn’t tribal loyalty – it’s recognition of a measurable pattern. A small number of training operations have produced a disproportionate share of Aintree winners and placed horses over the last two decades, and the pattern holds even when you strip out individual superstar horses and look at the preparation method rather than the pedigree.
This article works through the trainer record, the jockey experience that matters at the National fences, the specific profile of first-time Aintree runners, and how to use these markers for bet selection. The statistical base rates aren’t small-sample quirks. They’re the result of yards and riders that understand something about Aintree the rest of the racing world learns more slowly.
Trainer success rates over the last decade
Willie Mullins, Gordon Elliott, Paul Nicholls, Nicky Henderson and a handful of specialist Irish operations account for a grossly disproportionate share of National-placed horses and winners since 2015. Mullins in particular has shifted the landscape – before 2015 he’d never won the Grand National; since then his yard’s National presence has grown every year, with a Closutton-trained horse or two placing almost every season. Gordon Elliott’s yard produces a similar pattern, with repeated placed finishers across multiple years and multiple ownership groups.
The underlying reason is that these yards treat the Grand National as a year-long preparation objective rather than a race you “point a horse at” in February. The horses targeted at Aintree typically have specific winter campaigns designed to peak them in April – a Welsh National or Classic Chase in early winter, a mid-season prep, a final blow-out at the right trip. Yards without this infrastructure target the race more opportunistically, and it shows in the results.
The statistical signal is strong enough to use as a filter. In a 40-runner National, roughly a third of the field typically comes from the top five or six trainers by yearly strike rate at Aintree; that third of the field produces well over half of the top-four finishers across the last decade. If you’re cutting the field down to an each-way shortlist, starting with the horses from those yards and working outward is a better filter than starting with the market and working inward.
Jockey experience at the fences
The Aintree fences are unique in British racing – not in absolute height, because they were modified in 2012 to reduce the drop-and-spruce profile, but in the specific jumping demands they place on horse and rider. The angle of approach to Becher’s, the Canal Turn, the pack management required in the first circuit with 40 horses crowded into tight lines – these are things experienced jockeys execute automatically and novice jockeys get wrong.
The data point worth absorbing: jockeys with more than five previous Grand National rides win the race at a rate roughly three times higher than jockeys riding their first, second or third National. The gap narrows with accumulated rides rather than disappearing – a jockey with fifteen Grand National rides isn’t massively better than a jockey with seven – but the step up from inexperience to experience is real and measurable. A novice jockey on a well-fancied horse is, at the margins, a small negative.
Within the experienced pool, a sub-category worth watching: jockeys who’ve won at the Grand National meeting in the days before the big race – on the Thursday or Friday card. Over the last decade, a handful of National winners came from jockeys who’d ridden a winner earlier in the three-day meeting, suggesting confidence, course adaptation, and rhythm with the local ground are compounding factors by the Saturday. It’s not a hard rule, but it’s a valid tiebreaker between otherwise similar horses.
First-time Aintree runners
Roughly 30 per cent of Grand National punters are first-timers or lapsed returners, which is a mass-market characteristic of the race. The same cannot be said of the horses. First-time Aintree runners – horses making their first attempt at the Grand National fences – win the race rarely compared to their share of the field. The National fences remain a different proposition from ordinary chase fences even in their post-2012 configuration, and a horse that has never schooled over them on a race day carries a measurable handicap.
The usual indicator to look for is the Becher Chase in December – a three-mile-two-furlong handicap chase run over the Grand National fences on the Aintree course. A horse that has run in the Becher, completed the course, and shown some jumping ability over the specific fences is in a meaningfully different category from a horse that has never jumped those obstacles competitively. The Topham Chase, run on the Thursday of the Grand National meeting itself, is another Aintree-fences race; horses that have completed a Topham are similarly advantaged.
That’s not the same as saying first-time National runners never win. They do. The class of horse required to win the race first-time is higher, though – the horse has to be good enough to overcome the jumping disadvantage purely through class and stamina. That profile of horse typically sits toward the top of the market, which is another reason why mid-priced first-time National runners are poor value: they carry the jumping disadvantage without the compensating class.
Using stats for bet selection
My practical framework for reading the Grand National field, based on these patterns, runs something like this. First pass: eliminate first-time Aintree runners below 10/1 in the market, unless they come from Mullins or Elliott and have a confirmed prep over analogous fences. That removes perhaps a quarter of the field at a stroke. Second pass: prioritise horses from the top-strike-rate trainers, particularly those carrying weights in the 10–8 to 11–3 bracket I covered earlier in this series. That shortlist is typically eight to fifteen horses.
Third pass: jockey experience. Within the shortlist, preference goes to experienced National jockeys, with an additional small weighting for anyone who has won earlier at the meeting. Fourth pass: recent form. A respectable run in a major winter stayers’ chase – the Welsh National, the Classic Chase, the Becher, a top-weight run at Haydock – is the recent-form signal that maps best to Aintree success. Breeding and pedigree enter the calculation only as tiebreakers; the core signal is preparation-and-execution, which trainer and jockey stats capture.
Two additional notes. British racing’s economic scale – around 85,000 jobs supported by the industry and 20,000 people working directly at 59 licensed racecourses and over 500 training yards – means the talent concentration in the top yards compounds year on year. The top yards attract the best staff, the best owners, the best horses, and the best retained jockeys. That compounding is why the pattern holds. It isn’t about lucky runs; it’s about the ecology of the sport reinforcing a stable hierarchy.
The other note: UK attendance in 2025 hit 5.03 million, the first time above 5 million since 2019, with Aintree contributing a significant chunk of that figure. A crowded betting market on Grand National day doesn’t change the underlying trainer-jockey signals, but it does mean prices get shorter on the obvious form horses as casual money piles in on names casual punters recognise. Trainer and jockey stats analysis remains a sharper filter precisely because the mass market works from other signals.
For the wider picture of Grand National betting – ante-post markets, weight analysis, each-way strategy – our Grand National betting guide sets the trainer and jockey patterns alongside the other angles that decide the race.
Does a winning trainer at Aintree repeat?
Often, yes – but not in back-to-back years necessarily. The top yards by Aintree strike rate produce placed horses or winners in most years, though the specific horse changes. A trainer who won the National one year is more likely than average to have a placed horse the next, simply because the yard’s preparation methods produce multiple National-capable stayers across seasons. Tracking yard records over five-year windows is more useful than looking at last year’s winner.
Are novice jockeys ever worth backing?
Occasionally, when the novice is riding a top-class horse where the jockey is the junior variable. The data shows inexperienced Grand National jockeys win at materially lower rates than experienced ones, but exceptional horses do carry inexperienced riders to victory on rare occasions. If you’re backing a novice jockey, the horse needs to be good enough to win the race despite the jockey factor, not because of anything the jockey brings to it.
