Saffie Osborne became the first female jockey to win a British Classic when she rode Highwayman to victory in the 2026 St Leger at Doncaster.
The 24-year-old produced the biggest victory of her career aboard the Joseph O’Brien-trained colt, beating stablemate Enceladus by two and a half lengths in the 250th running of the world’s oldest Classic.
Highwayman was sent off at 11/1 and defeated a field containing Derby winner Christmas Day and several of the leading three-year-old stayers of the season.
For Osborne, the significance extended well beyond a first St Leger success. No female jockey had previously ridden the winner of the 2,000 Guineas, 1,000 Guineas, Derby, Oaks or St Leger.
That changed at Doncaster on 12 September 2026.
2026 St Leger Result
The St Leger was run over one mile, six furlongs and 115 yards on good ground at Doncaster Racecourse.
Eleven horses contested the Group 1.
| Position | Horse | Jockey | Trainer | Starting Price |
|---|---|---|---|---|
| 1st | Highwayman | Saffie Osborne | Joseph O’Brien | 11/1 |
| 2nd | Enceladus | Billy Loughnane | Joseph O’Brien | 5/2 |
| 3rd | Amelia Earhart | Tom Marquand | Aidan O’Brien | 22/1 |
| 4th | Alderman | Rossa Ryan | Richard Hannon | 40/1 |
| 5th | Galiyan | Daniel Tudhope | Andrew Balding | 40/1 |
Highwayman defeated Enceladus by 2½ lengths, with another 4¼ lengths back to Amelia Earhart in third.
The result gave Joseph O’Brien first and second in one of British racing’s five Classics.
How Saffie Osborne Won the St Leger
Highwayman entered the race as one of the less-fancied runners in the market.
The colt started at 11/1, while Enceladus went off at 5/2 and Pierre Bonnard at 3/1.
Osborne kept Highwayman travelling comfortably before asking him to make his challenge.
Enceladus emerged as the principal threat under Billy Loughnane, but Highwayman responded when challenged and pulled clear.
The winning margin was 2½ lengths.
It was a performance that combined stamina with the ability to quicken late in a race run over almost one mile and seven furlongs.
For a horse officially rated 101 before the race, defeating Enceladus, who entered with an official rating of 112, represented a significant step forward.
Highwayman also beat several runners carrying considerably stronger pre-race reputations.
Saffie Osborne Becomes the First Female Jockey to Win a British Classic
The historical importance of the result is difficult to overstate.
British Flat racing has five Classics:
- 2,000 Guineas
- 1,000 Guineas
- Derby
- Oaks
- St Leger
They have been central to British racing for centuries.
Before 12 September 2026, no female jockey had won any of them.
Saffie Osborne is now the first.
The achievement came in the 250th running of the St Leger, adding another piece of racing history to an event first staged in 1776.
Osborne’s victory also came on her first ride for trainer Joseph O’Brien.
She had only learned that she would ride Highwayman a few days before the race.
By Saturday afternoon, the partnership had made British racing history.
A Landmark Moment for Female Jockeys
Osborne’s achievement follows several important milestones for female jockeys in British and European racing.
Alex Greaves became the first woman to ride a Group 1 winner in Britain when Ya Malak dead-heated with Coastal Bluff in the 1997 Nunthorpe Stakes.
Hayley Turner subsequently became the first woman to ride a British Group 1 winner outright when Dream Ahead won the July Cup in 2011.
Hollie Doyle broke further ground aboard Nashwa in 2022, becoming the first female jockey to win a European Group 1 Classic when taking the Prix de Diane, the French Oaks.
Saffie Osborne has now added the landmark that remained in British Classic racing.
She is the first woman to ride a British Classic winner.
The fact that it happened in the St Leger’s 250th running gives the result an obvious place in the race’s history.
Why the St Leger Victory Matters
The importance of Osborne’s win comes from the status of the race as much as the identity of the winning jockey.
The St Leger Stakes is the oldest of Britain’s five Classics.
First run in 1776, it predates the Derby, Oaks and both Guineas races.
Its position at the end of the British Classic season also creates a different test from the earlier Classics.
The St Leger is run over approximately one mile and six and a half furlongs. Three-year-olds need the stamina to handle the distance while retaining enough speed to compete at Group 1 level.
That combination has produced some of British racing’s most important winners.
Osborne and Highwayman now occupy their own place in that history.
Highwayman’s Remarkable Rise
The story is not solely about the jockey.
Highwayman’s progression during 2026 has been substantial.
The Persian King colt had shown little during the early part of his career but improved markedly when tackling longer distances.
By the time he arrived at Doncaster, Highwayman had won his previous two starts.
The St Leger made it three consecutive victories.
His success was also a first Group 1 victory for his sire Persian King.
That improvement provides another example of why bare finishing positions do not always tell the complete story when reading horse racing form.
Distance, development, race conditions and the stage of a horse’s career all matter.
Highwayman developed into a much stronger performer once his stamina became an asset.
At Doncaster, that progression reached Group 1 level.
Highwayman Defies His Official Rating
One of the most interesting aspects of the result was the difference between Highwayman’s pre-race Official Rating and those of several rivals.
Highwayman entered the St Leger rated 101.
Runner-up Enceladus was rated 112, while Pierre Bonnard carried an Official Rating of 116.
On those figures alone, Highwayman had plenty to find.
He beat both.
That does not make horse racing handicap ratings ineffective. Ratings describe what a horse has demonstrated up to that point.
Improving three-year-olds can progress beyond their existing marks.
Highwayman’s St Leger performance was considerably better than his previous rating suggested he would need to produce.
It is a useful example of why race analysis should combine ratings with recent progression, distance suitability and the conditions of the race.
Joseph O’Brien Trains the First Two Home
Joseph O’Brien enjoyed an exceptional result by training both Highwayman and runner-up Enceladus.
Enceladus was much shorter in the betting and arrived at Doncaster with an Official Rating 11lb higher than Highwayman’s.
Billy Loughnane appeared to have a serious chance of passing Osborne as the pair fought out the finish.
Highwayman found more.
The stable one-two gave O’Brien another major British success in a career that has already included victories at the highest level as both jockey and trainer.
There was another family connection behind them.
Aidan O’Brien trained third-placed Amelia Earhart, who finished 6¾ lengths behind the winner.
What Happened to Derby Winner Christmas Day?
Christmas Day entered the St Leger attempting to add another Classic to his Derby victory.
He started among the leading contenders but failed to reproduce his best form and finished ninth.
The result demonstrated the different demands of the two Classics.
The Derby is run over a mile and a half at Epsom.
The St Leger asks three-year-olds to stretch their stamina over another two and a half furlongs at Doncaster.
Winning at Epsom does not guarantee that a horse will prove equally effective over the longer St Leger distance.
Christmas Day’s defeat left Highwayman to emerge as the final British Classic winner of 2026.
An 11/1 Winner in a Competitive Classic
Highwayman’s 11/1 starting price showed that victory was not considered a shock on the scale of a huge outsider winning, but he was clearly some way down the market.
An 11/1 price represents fractional odds where a £1 winning stake produces £11 profit plus the returned £1 stake.
A £10 win bet at 11/1 would therefore return £120 in total, consisting of £110 profit and the £10 stake.
Our explanation of what 11/1 odds mean covers the price in more detail.
The result also provides a useful example of why the shortest-priced runner does not necessarily have the strongest chance once the race is actually run.
Enceladus started at 5/2 and Pierre Bonnard at 3/1.
Highwayman beat them both.
Price reflects the market’s assessment before the race. It does not determine the result.
The St Leger in Numbers
The 2026 race produced several figures that underline its significance:
| St Leger 2026 Statistic | Figure |
|---|---|
| Running of the St Leger | 250th |
| Runners | 11 |
| Distance | 1m 6f 115yds |
| Winner | Highwayman |
| Winning SP | 11/1 |
| Winning margin | 2½ lengths |
| Highwayman’s pre-race OR | 101 |
| Runner-up Enceladus OR | 112 |
| Third-placed Amelia Earhart SP | 22/1 |
| First prize | £396,970 |
| Female British Classic winners before 2026 | 0 |
| Female British Classic winners after 2026 | 1 |
The £396,970 first prize formed part of a race worth £700,000 in advertised prize money.
Those numbers provide the context, but the statistic that will remain attached to the race is much simpler:
Saffie Osborne became the first female jockey to win a British Classic.
What the Victory Means for Saffie Osborne
The St Leger was Osborne’s first Group 1 victory.
That alone would make it a major career breakthrough.
Achieving it in a British Classic places the victory on a different level.
Osborne had already established herself among Britain’s leading Flat jockeys, but Classic success provides a permanent entry in racing’s record books.
At 24, she has achieved something no female rider before her managed in Britain.
The victory should also strengthen her position when major trainers and owners make riding arrangements for future Group and Classic races.
Winning opportunities at this level remain difficult to secure for any jockey.
Osborne took hers.
A Significant Day for British Racing
British racing has seen female jockeys establish themselves at the highest level over several decades.
The question of when a woman would win a British Classic remained unanswered.
It no longer does.
Osborne’s St Leger success deserves recognition as a racing achievement first. Highwayman needed to stay the distance, beat higher-rated horses and defeat a competitive Group 1 field.
Osborne needed to deliver when given the opportunity.
She did.
The historical significance followed from the result.
Future female jockeys riding in British Classics will no longer be trying to become the first to win one.
Saffie Osborne has already done it.
Highwayman Joins the St Leger Roll of Honour
Highwayman’s name now sits on the St Leger roll of honour alongside generations of Classic stayers.
The circumstances make the 2026 result particularly memorable.
It was the 250th running.
Highwayman started at 11/1.
Joseph O’Brien trained the first two.
The Derby winner was beaten.
And a female jockey won a British Classic for the first time.
Plenty of St Legers have produced outstanding horses.
The 2026 running produced a piece of history that extends beyond the winner himself.
What Comes Next for Highwayman?
Highwayman’s progression over staying distances will make his next move particularly interesting.
The St Leger established him as a Group 1 winner over an extended trip, but his future programme will depend on where connections believe his strengths can be used most effectively.
His three-race winning sequence suggests his improvement has coincided with being given a greater stamina test.
Future races over staying distances would therefore attract obvious attention.
His St Leger performance will also provide much stronger evidence when assessing his future horse racing form.
The horse who arrived at Doncaster rated 101 leaves as a British Classic winner.
What Comes Next for Saffie Osborne?
Osborne leaves Doncaster with something even more permanent.
Jockey careers are measured through winners, championships, major races and opportunities at the highest level.
A British Classic victory belongs in a smaller category.
There are only five opportunities each season.
Many outstanding jockeys never win one.
Osborne has now won the oldest of them.
The immediate attention will understandably focus on her becoming the first female rider to achieve the feat, but the longer-term consequence could be the opportunities the performance creates.
Major-race success earns major-race rides.
For Osborne, the 2026 St Leger could prove the point at which an already successful career moved firmly onto racing’s biggest stage.
