2026 St Leger Preview: Christmas Day Takes Centre Stage at Doncaster

The final Classic of the British Flat season takes centre stage at Doncaster on Saturday as the Betfred St Leger celebrates a landmark 250th running, with Derby winner Christmas Day heading a fascinating cast of three year olds on Town Moor.

The 250th running of Britain's oldest Classic brings together a Derby winner, a rapidly improving Royal Ascot scorer and another formidable O'Brien family challenge.

St Leger 2026 Key Facts

A Classic with a bit more history than usual

The St Leger never needs much help when it comes to history, but Saturday's renewal has more of it hanging over the race than most. Doncaster stages the 250th running of the world's oldest Classic and, fittingly, the horse at the head of the market is already a Classic winner.

Christmas Day arrives as the Derby winner attempting a double that has disappeared from modern racing. Reference Point was the last horse to win both Epsom and Doncaster, back in 1987. Thirty nine years later, Aidan O'Brien has a colt with the opportunity to finally end that wait.

The numbers also tell their own story. Twelve horses were left in at Monday's confirmation stage and seven of them are trained by Aidan or Joseph O'Brien. Ballydoyle has Christmas Day, Pierre Bonnard, Amelia Earhart, Piazza San Marco and Action, while Joseph O'Brien has Enceladus and Highwayman. Final declarations are due on Thursday, so the shape of the field can still change.

Christmas Day has the class, now comes the stamina test

Christmas Day earned his place at the top of this field at Epsom, where he won the Derby, but his two runs since have made the St Leger more interesting rather than less. He was beaten by Benvenuto Cellini in the Irish Derby and then finished third behind Maltese Cross and Pierre Bonnard in the Great Voltigeur at York.

That York run should not automatically be treated as evidence that Pierre Bonnard has his measure. Christmas Day was returning from a break, the Great Voltigeur was a trial rather than the end target, and Doncaster asks a very different question over almost a mile and three quarters.

There is also a neat family connection. Christmas Day is by Camelot, whose own attempt to complete the Triple Crown ended in defeat to Encke in this very race in 2012. His son now gets the chance to win the Classic that escaped him.

The key question is straightforward: does Christmas Day stay? He has the strongest piece of form in the race courtesy of his Derby victory, but Saturday takes him beyond a mile and a half for the first time. If he settles and sees out the final two furlongs, the others have to find a way of dealing with a Derby winner. If he does not, the St Leger has a habit of exposing it.

Derby Winners Who Also Won the St Leger

Pierre Bonnard cannot be dismissed as the other Ballydoyle horse

Pierre Bonnard is easy to frame as the stablemate of the favourite, but his Great Voltigeur second gives him a perfectly legitimate claim of his own. He finished in front of Christmas Day at York and was beaten two lengths by Maltese Cross, who carried a 5lb penalty after his Grand Prix de Paris success.

Maltese Cross would have brought some of the strongest form into this race, but William Haggas has opted to bypass Doncaster and aim him at the Prix de l'Arc de Triomphe. That decision removes the horse who beat both Pierre Bonnard and Christmas Day at York and leaves the two Ballydoyle colts to represent that form line.

For Pierre Bonnard, the attraction is obvious. He has already shown he belongs in this company and his profile suggests the extra distance could suit. The concern is that Aidan O'Brien himself has indicated he expects the longer trip to play particularly strongly to Christmas Day's strengths. That makes the rematch much more interesting than simply taking the York finishing order at face value.

Enceladus brings the progressive profile

If Christmas Day is the established Classic horse, Enceladus is the one still climbing. Joseph O'Brien's Sea The Stars colt has developed quickly through the summer, winning the King George V Stakes at Royal Ascot before stepping into Group company and taking the Gordon Stakes at Goodwood.

Those two victories have pushed him right into St Leger contention. He has not yet had to produce a Derby level performance, but he has also not stopped improving, and the way he has progressed as his stamina has been tested is exactly what makes him dangerous at Doncaster.

There will be a new jockey aboard. Dylan Browne McMonagle remains sidelined following his fall at Bellewstown, so Joseph O'Brien has secured Billy Loughnane for the ride. Loughnane was understandably pleased to get the call.

It's a fantastic ride to pick up.

Loughnane also pointed to the colt's steady progression through the season, describing Enceladus as a horse who has been moving through the ranks smoothly. Saturday is clearly a much harder assignment, but he arrives as one of the few runners whose limit is still difficult to pin down.

Joseph O'Brien has been positive without getting carried away. His update on the pair was simple:

Both horses are preparing well.

That understated line probably sums up the appeal of Enceladus. He does not need excuses or a revival, he comes to Doncaster in form and moving in the right direction.

Highwayman is the less obvious Joseph O'Brien threat

Highwayman sits further down the betting but has made striking progress of his own. The son of Persian King took six attempts to win, then suddenly found another level when bolting up by nine lengths at Killarney in July. He followed that by winning the Listed Vinnie Roe Stakes at Leopardstown.

This is a major jump in class and nobody in the camp is pretending otherwise. Joseph O'Brien summed up both sides of the argument in one sentence:

It's a big step up in class for Highwayman but he's progressive, so you never know.

That is about right. His bare form leaves him with something to find against the principals, but he is improving at precisely the right time and has looked increasingly comfortable as the distances have stretched out. Saffie Osborne is booked to ride.

Amelia Earhart adds another angle to Ballydoyle's hand

Amelia Earhart is the only filly among the twelve confirmations and gives Aidan O'Brien another possible route into the race. She had been associated with the Park Hill Stakes, run over the St Leger course and distance, but connections have left open the possibility of tackling the Classic instead.

She would receive the sex allowance from the colts and, more importantly, her presence would give Ballydoyle another runner with a different profile to Christmas Day and Pierre Bonnard. Whether she ultimately takes her chance will become clear at declarations.

Hatteen heads a relatively thin home challenge

With Maltese Cross heading towards Paris and Del Maro absent from Monday's confirmations, the British trained challenge does not have the depth it once threatened to have. Andrew Balding's Hatteen is the shortest priced home contender and at least brings proven Doncaster form to the table.

Hatteen won the inaugural St Leger Trial at the track earlier in the season before finishing second to Infraad at Goodwood. He now has to translate that improvement into Group 1 company, but familiarity with Town Moor is no negative in a race where rhythm, balance and stamina all matter.

Balding also has Galiyan still involved, while Alderman, Golden Story and Rebel Rocker complete the British trained possibles at the confirmation stage.

Benvenuto Cellini's absence changes the picture

Benvenuto Cellini had looked an obvious St Leger player after beating Christmas Day in the Irish Derby, but his Prix Niel run at Longchamp did little to strengthen the case for Doncaster. Sent off odds on, he finished only fifth behind Varandir.

Sporting Life's assessment of the performance was particularly concise, describing the favourite as:

simply not showing up

With Benvenuto Cellini no longer among the twelve confirmations, the Irish Derby form is left looking rather different. Christmas Day no longer has to reverse that Curragh result on Saturday, while one of Aidan O'Brien's most obvious alternatives has disappeared from the equation.

The ground: good to soft, but probably drying

The going was good to soft on Monday and the forecast does not currently suggest a dramatic change before the meeting begins on Thursday. Clerk of the course David Attwood said the recent rain had arrived at exactly the right time after a hot summer.

The rain came for us about seven or 10 days ago and the track has absolutely popped, it looks a million dollars.

The expectation is for a mainly dry week with only the possibility of showers. If that forecast holds, Attwood believes good could enter the description by Thursday. In other words, this does not currently look like a St Leger that will be turned into a slog by testing ground.

That matters. An easy side of good surface should give the classier mile and a half horses every opportunity to travel into the race, while the final part of the contest will still ask the stamina question that defines the St Leger.

Doncaster is preparing for a proper 250th celebration

The anniversary is not being treated as just another running. Doncaster has altered parts of the site for an expected crowd of around 30,000, including larger enclosures and changes around the parade and winner's enclosure.

Attwood said the target remains a bumper St Leger Saturday crowd:

We've always aimed to have 30,000 people here on St Leger Saturday.

Prestige, Premier and County areas were already reported as sold out on Monday, with limited hospitality and tickets in other areas still available. The racecourse has also been working with the local community in the build up to the anniversary.

The twelve horses still standing

These are the horses remaining after Monday's confirmation stage. The final field and rider bookings will be established at Thursday's declarations.

What the betting tells us

At Monday's confirmation stage Christmas Day was 13/8 favourite with Paddy Power and Sky Bet, ahead of Enceladus at 5/2 and Pierre Bonnard at 11/4. Hatteen was 12/1 and Highwayman 14/1, with the remainder at 25/1 or bigger.

Prices can move sharply between confirmations and final declarations, so those odds are best treated as a snapshot. What is more revealing is the shape of the market: the three shortest priced horses are all trained by Aidan or Joseph O'Brien, which underlines just how much of Saturday's race revolves around one family.

A St Leger that asks a very simple question

For all the history surrounding the 250th running, the race itself boils down to the same question the St Leger has been asking three year olds for generations: who still has something left when the race moves beyond a mile and a half?

Christmas Day has already proved he possesses Classic class. Pierre Bonnard has already finished in front of him in their principal trial. Enceladus has spent the summer improving every time he has been asked to do more. Highwayman is trying to make an even bigger leap, while Hatteen carries the strongest home hopes.

That is what gives Saturday's race its edge. Christmas Day does not have to prove he is the best horse at a mile and a half, Epsom has already made a powerful case for that. He has to prove he is still the best horse when another two furlongs are added.

If he does, he becomes the first Derby winner since Reference Point to add the St Leger and gives Aidan O'Brien a tenth victory in the race. If he does not, there are enough improving stayers around him to make the final Classic of the season anything but a formality.

For the 250th St Leger, that feels like exactly the sort of contest Doncaster would have wanted.

How to bet the St Leger

• Each way betting can make sense in a Classic where stamina questions are still unanswered, with most firms paying three or four places.
• Compare prices across bookmakers before you take one, since the market often moves after Thursday's declarations.
• Non runner no bet offers protect your stake if your selection is withdrawn before the off.

Please gamble responsibly. Only stake what you can afford to lose and take a break if betting stops being fun.
