Grand National Entries Trend – Why Numbers Are Falling

In 2015, 126 horses were entered for the Grand National. In 2026, that number was 78. The decline — roughly 38% over a decade, or about 13% per year on a compounding basis — has been steady, consistent, and largely unnoticed by the general public. Casual bettors picking their Grand National selections from a list of 34 final runners have no reason to know that the pool of horses those runners were drawn from has nearly halved. But the decline matters, because it reflects structural changes in the sport that are reshaping the Grand National from the ground up: fewer horses, bigger stakes, and a race that is becoming more selective, more concentrated, and arguably more competitive than it was a decade ago.

The entry trend is not merely a statistical curiosity. It is a signal — of how trainers approach the race, how the regulatory environment affects participation, and how the quality of the Grand National field is evolving. According to horseracing.guide data, the decline is broad-based: both British and Irish entries have fallen, though British entries have dropped more steeply.

The Numbers: Decade of Decline

The trajectory is clear from the raw data. In 2015, 126 initial entries. By 2018, that had fallen to approximately 110. By 2021, it was in the low 100s. By 2024, when the maximum field was reduced from 40 to 34, the entry figure dropped below 90. And in 2026, it hit 78 — the lowest in recent memory. Each year, the number has been lower than the last or, at best, stable. There has been no recovery year, no bounce-back, no sign that the trend is about to reverse.

What makes the decline particularly striking is that it has occurred against a backdrop of stable or even increasing betting turnover on the Grand National itself. The race still generates approximately £250 million in total wagers. It still attracts millions of viewers. It is still the most bet-on event in British sport. The commercial appeal of the Grand National has not diminished — but the number of horses whose connections consider it worth entering has fallen by more than a third.

The composition of the entries has shifted too. Of the 78 entries in 2026, only 29 came from British-based trainers. A decade ago, British entries formed the majority. The decline has been driven disproportionately by British yards, many of which have stepped back from the Grand National as the risks — physical, financial, and reputational — have come under greater scrutiny. Irish trainers still enter in large numbers, but even their totals have fallen from the peak years.

Causes: Field Reduction, Affordability, and Trainer Consolidation

Three factors converge to explain the decline. The first is the reduction of the maximum field from 40 to 34 runners in 2024. This decision, taken by the Jockey Club on safety grounds, had a direct knock-on effect on entries. When only 34 of 78 entries can make the final field, the horses ranked 35th through 78th on the handicap know they face an uphill battle to secure a place. Their connections — trainers and owners — increasingly decide that the cost of entering, preparing, and campaigning a horse that is unlikely to make the final cut is not justified. The field reduction, designed to make the race safer, has inadvertently accelerated the entry decline by reducing the incentive for borderline runners to enter at all.

The second factor is the broader regulatory and financial environment. Affordability checks imposed on bookmakers have contributed to a decline in betting turnover on horse racing generally, which in turn has reduced the levy income that funds prize money and racecourse infrastructure. Trainers whose owners are motivated in part by the prospect of prize money recouping training costs find the economics less compelling when the industry’s financial outlook is uncertain. The Grand National’s million-pound purse remains attractive, but the pathway to reaching the race — months of training, preparation runs, entry fees, travel costs — is expensive, and the probability of making the final 34 is lower than ever.

The third cause is the consolidation of the staying chase division around a smaller number of powerful training operations, predominantly in Ireland. Willie Mullins and Gordon Elliott between them account for a significant share of entries, and their systematic approach — entering multiple horses and withdrawing the less favoured ones at the confirmation stage — means a large proportion of entries come from just two yards. Smaller British operations that might once have entered a speculative Grand National runner now face the dual disincentive of a high-quality Irish-dominated field and a reduced maximum field that makes getting a run less likely.

Impact on Betting Market Quality

For bettors, the declining entry trend has a paradoxical effect: it improves the quality of the betting market. When entries were at 126, a substantial number of those horses had no realistic prospect of making the final 40. They padded the ante-post market with long-priced runners that attracted casual money but never appeared at Aintree. At 78 entries for 34 places, the ratio of entries to runners is much tighter, and a higher proportion of entered horses are genuine contenders with active Grand National campaigns.

This means the ante-post market is more efficient than it was a decade ago. The prices more closely reflect the actual competitive landscape, because fewer phantom entries distort the early-market odds. For form analysts, the smaller entry pool is easier to study comprehensively — 78 horses is a manageable research project; 126 was a data deluge that encouraged lazy shortcuts.

The trade-off is reduced variety. Fewer entries means less chance of the rank outsider that nobody considered suddenly making the final field and producing a 100/1 shock. The Grand National’s reputation for chaos and unpredictability — its core appeal to the casual betting public — may gradually erode as the entry pool shrinks and the field becomes more tightly curated. Whether that is a problem depends on your perspective: if you value form over randomness, the current trend is a positive development. If you value the Grand National’s capacity for the utterly unexpected, the declining entries are a loss.

Key Takeaway

Grand National entries have fallen from 126 to 78 in a decade, driven by the field reduction, regulatory pressures, and the consolidation of power among a handful of Irish training operations. The smaller entry pool has improved the quality and efficiency of the betting market but reduced the diversity of the field. For bettors, the practical consequence is an ante-post market that is sharper, more competitive, and harder to find value in — but one where the analysis required to find that value is more focused and more rewarding when it pays off. Fewer horses, bigger stakes: the Grand National is becoming a race of specialists, not speculative hopefuls.
