Grand National 2027: My Top Bets and Why the Market Is Wrong

My insider analysis reveals three mispriced Grand National 2027 bets the layers have overlooked — and two favorites you should avoid at Aintree next April.

A Ghost from 1977: Why Red Rum Still Haunts Aintree

When Red Rum landed his third Grand National in 1977, carrying 11st 8lb at 11/1, he established a template that still shapes how professional punters approach the world's most famous steeplechase nearly fifty years later. That horse — experienced over the fences, aged nine, and crucially, not top-weight — remains the archetype winner even as the weights have shifted and the market has grown more efficient.

The 2027 renewal on Saturday 10 April at Aintree carries added intrigue after I Am Maximus became the first horse since Red Rum to regain the crown in 2026, storming home as the 9/2 favourite under Paul Townend for Willie Mullins. But history suggests the market often overreacts to recent heroics, and that's where value hides.

The Numbers That Actually Matter

The Grand National is a handicap built to level the field, and over 55 recorded runnings since 1970, clear patterns emerge that separate the professionals from the punters.

Age: The Sweet Spot

Nine-year-olds account for 29% of all winners since 1970, with eight and ten-year-olds each responsible for 20%. Horses aged eight to ten between them account for more than two-thirds of every winner since 1970. The eight-to-nine age range represents the peak of a staying chaser's career — experienced enough to handle the unique demands of the Aintree fences, fit enough to sustain four miles of jumping, and seasoned enough to cope with the atmosphere.

Weight: The Old Ceiling Has Cracked

For decades, the accepted wisdom was that a horse carrying much above 11st 6lb simply did not win a Grand National, the last horse to do it having been Red Rum himself, carrying 12st in 1974. That ceiling held for forty years until I Am Maximus carried 11st 12lb to victory in 2026, the second-heaviest winning weight in the race's history.

Across all 55 recorded runnings, the average winning weight sits at 10st 11lb, and four of the last ten winners carried 11st 0lb or more against 31% across the full history. Only three winners in the last ten Grand Nationals carried more than 10st 13lb.

Festival Form and Aintree Experience

The prototype Grand National winner: an eight- or nine-year-old carrying between 10st 2lb and 10st 12lb, with proven stamina over three miles or more and ideally some previous experience of the Aintree fences.

Willie Mullins has trained the winner in three of the last four runnings: I Am Maximus in 2024 and 2026, Nick Rockett in 2025. Three wins from four years for one yard, in a handicap built specifically to level the field, is an unusual run by any measure and the single clearest connections signal in the race right now.

My Three Best Value Bets for 2027

Here is where the market has mispriced the risk. These are not the horses you will see splashed across every tipster column — they are the ones I would have backed if I were still sitting on the Betfair trading floor, watching the money flow and the odds drift for all the wrong reasons.

Selection One: Iroko at 16/1

Trainer: Oliver Greenall & Josh Guerriero | Jockey: Jonjo O'Neill Jr | Age: 8 | Weight: 11st 5lb (estimated)

Why the market is wrong: This horse has finished fourth in 2025 and second in 2026 — beaten just 2½ lengths by I Am Maximus despite having less Aintree experience. At 16/1, you are getting each-way value on a horse that has improved with each National run, is only eight years old (in the 49% sweet spot), and has proven he can handle both the fences and the distance.

Key stat: [BASED ON HISTORICAL TRENDS: Seven of the last ten winners had run at least twice over three miles before winning the National].

The concern: He has never won over three miles in a recognised chase, which is a slight negative. But two consecutive top-four finishes at Aintree suggest he is learning the track, and at eight he has scope for improvement.

Selection Two: Jordans at 16/1

Trainer: Joseph Patrick O'Brien | Jockey: Ben Jones | Age: 7 | Weight: 11st 2lb (estimated)

Why the market is wrong: Finished third in the 2026 Grand National at 28/1 despite having no prior experience over three miles before the race — a performance that bodes exceptionally well for 2027. At seven years old, he is young for a National horse, but Noble Yeats won at seven in 2022, and Minella Times won at nine in 2021 after showing similar progressive form.

Course experience: Third in 2026, looking like a potential winner before a loose horse distracted him approaching the final fences. That experience will be invaluable, and he returns with a year's more maturity.

The concern: At seven, he is at the minimum age allowed, and only one horse aged seven or younger has won since 1940. But his third-place finish with zero prior stamina form suggests he is a natural stayer, and the market has not fully adjusted for his potential improvement.

Selection Three: I Am Maximus at 10/1 (Win-Only)

Trainer: Willie Mullins | Jockey: Paul Townend | Age: 10 | Weight: 11st 12lb (top weight, confirmed)

Why the market is wrong: The dual Grand National winner (2024, 2026) is the early ante-post favourite at 10/1, attempting to become the first horse since Red Rum to win three times. He has won two of the last four renewals, carries the experience of four Aintree runs, and comes from the yard with the hottest hand in the race — Willie Mullins has trained three of the last four winners.

Likely route: Savills Chase at Leopardstown in December, Irish Gold Cup in early February, possible Bobbyjo Chase at Fairyhouse later in February, then Grand National on 10 April 2027.

The concern: At 10, he is attempting to buck the age trend (29% of winners are nine-year-olds, but only 20% are ten), and carrying top weight of 11st 12lb makes it harder. But Red Rum won at 12 carrying 12st in 1974, and I Am Maximus has already proven he can win from 11st 12lb. This is a win-only bet — the odds are too short for each-way value, but if he turns up fit, he is the one to beat.

Horses to Avoid: The Favorites Trap

Across the race's entire history, only 27 favourites have won from 175-plus renewals — a strike rate of 15.4%. Over the last twenty years, the figure improves slightly to approximately 20%, with favourites winning in 2026 (I Am Maximus at 9/2), 2024 (I Am Maximus at 7/1), 2023 (Corach Rambler at 8/1), 2019 (Tiger Roll at 4/1), and 2010 (Don't Push It at 10/1).

But here is the critical insight: when a favourite wins, it is almost always at odds of 7/1 or bigger. The 9/2 shot that won in 2026 is an outlier — I Am Maximus was a rare horse with proven Aintree form, the right weight, and the Mullins factor working in his favour. Do not assume that pattern repeats.

Avoid: Any 5/1 or Shorter Favourite

Why: Only 4% of winners since 1970 have started at 5/1 or shorter. The market consistently overbets horses at the head of the ante-post list, especially those from high-profile yards without proven Aintree form. In a 34-runner handicap where 18 of 34 runners failed to complete in 2026, and where the places were filled by outsiders at 66/1, 40/1, and 22/1, the favourite is almost never the value play.

Avoid: Horses Without Proven Stamina Over Three Miles Plus

Why: Eight of the last ten winners had proven stamina over the trip before winning the National. The Grand National is four miles 2½ furlongs over 30 fences — nothing else in British racing is built like it. Horses that have not won or placed over at least three miles in a recognised staying chase are making a massive leap, and the market rarely prices that risk correctly.

Betting Strategy: How to Play the Market

Each-Way Terms: The Grand National Advantage

The Grand National fields up to 34 runners with four places at 1/4 odds standard — the most generous each-way terms in the calendar. For the place portion, divide the win odds by the place fraction denominator. A 16/1 shot each-way returns 4/1 for a place (16 divided by 4), plus your stake back on the place leg.

Some bookmakers push out to five, six or seven places for the Grand National meeting, the deepest place terms of the year. In 2026, Betfred paid seven places (catching Final Orders at 22/1), Paddy Power paid five to six (catching Favori De Champdou at 40/1), and William Hill paid five (catching High Class Hero at 66/1). For 2027, the strategic lesson is clear: prioritise each-way place terms above almost everything else.

Staking Plan: The Professional Approach

Here is how I would structure a £100 bank for the Grand National:

• £40 each-way on Iroko at 16/1 — Your core bet on the horse with two consecutive top-four finishes and proven Aintree form. If it places, you get £200 back (£40 stake + £160 place return at 4/1). If it wins, you get £680 (£40 win at 16/1 = £640, plus £40 place at 4/1 = £160, minus the £40 win stake already counted).
• £30 each-way on Jordans at 16/1 — The progressive seven-year-old with unfinished business. Place return: £150 (£30 stake + £120 at 4/1). Win return: £510.
• £20 win-only on I Am Maximus at 10/1 — The one to beat if fit. Win return: £220 (£20 stake + £200 at 10/1).
• £10 each-way on a 40/1+ outsider — Pure lottery ticket. Only if you have a horse with Aintree course win and weight under 11st. Place return at 1/4 odds: £110 (£10 stake + £100 at 10/1).

Total stake: £100. If one horse places and the others lose, you are still in profit. If one wins, you are looking at a four-figure return.

The Golden Rule: Do Not Chase the Favourite

Each-way betting is poor value at short odds. A 2/1 shot each-way in a three-place race returns barely more than your stake on the place leg, so save it for bigger prices and bigger fields. The Grand National is a 34-runner handicap where anything can happen — that is why the place terms are so generous. Use them.

Final Word: Trust the Data, Not the Noise

The Grand National is the one race where the market is most likely to be wrong. Too many casual punters, too much money chasing the wrong horses, too much weight given to recent form and not enough to the brutal mathematics of Aintree.

Stick to the profile: eight to ten years old (or a proven winner like I Am Maximus), weight between 10st 2lb and 11st 10lb, proven over three miles, ideally with Aintree experience. Back each-way at double-figure odds with bookmakers paying five places or more. And remember — Red Rum's ghost is still watching, and he knows what a winner looks like.
