The British Champions Fillies & Mares Stakes takes place at Ascot on Saturday 17 October 2026, bringing together leading middle-distance fillies and mares from different generations on British Champions Day. The Group 1 is run over just short of a mile and a half and carries £500,000 in guaranteed prize money.
Kalpana gives the 2026 renewal an exceptional storyline. Andrew Balding’s mare has won the race for the past two years and is being aimed at Ascot for an unprecedented third consecutive victory. She returns as a five-year-old having enhanced an already outstanding Ascot record by winning the King George VI and Queen Elizabeth Stakes earlier this season, before adding the Yorkshire Oaks at York in August.
The older mare is far from the only significant name among the entries. The three-year-old generation includes Epsom Oaks winner Thundering On and Irish Oaks winner Johanna Walsh, while Sunly, Minnie Hauk, Sparan Nua, Lilt and several other high-class fillies and mares remain engaged. With the Prix de l’Arc de Triomphe taking place less than two weeks before Champions Day, however, the final shape of the field will depend heavily on what happens at Longchamp.

British Champions Fillies & Mares Stakes 2026 Entries
The final runners have not yet been declared. There are currently 25 horses remaining in the race, but the maximum field is 14 and several of the leading entries have other major autumn targets.
Notable current entries include:
- Kalpana
- Sunly
- Thundering On
- Waardah
- Minnie Hauk
- Danielle
- Lilt
- Sparan Nua
- Johanna Walsh
- Tiffany
- Fairy Glen
- Nyra
These are entries rather than confirmed runners. Confirmation and supplementation take place on 12 October, after which the likely field should become considerably clearer.
The timing of the Prix de l’Arc de Triomphe is particularly important this year. Kalpana, Thundering On and other leading fillies and mares have had Longchamp under consideration, and a demanding race in Paris could influence whether connections ask them to return to action at Ascot only 13 days later. Rather than presenting every horse still engaged as an intended runner, we will update the field when those autumn plans have been resolved.
Kalpana Is Chasing an Historic Third Victory
Kalpana has made this race her own over the past two seasons. She first won as a three-year-old in 2024, when she completed a rapid rise through the ranks by defeating Wingspan and Tiffany, and returned twelve months later to produce an even more authoritative performance as a four-year-old.
Her 2025 victory came after a demanding campaign and only two weeks after she had finished seventh in the Prix de l’Arc de Triomphe. Despite that quick turnaround, Kalpana travelled strongly under Colin Keane, moved to the front more than two furlongs from home and pulled clear to beat Estrange by two and a half lengths. Quisisana finished third.
That second success made Kalpana only the third dual winner in the long history of the race, following Shebeen and Crystal Capella. Neither of those mares won three times, so another Kalpana victory in 2026 would create a new record.
Her affinity with Ascot extends well beyond this particular race. Kalpana has now won three Group 1 races at the course, and her ability to operate effectively there under different conditions is one of the strongest pieces of evidence in her favour whenever she returns.
Kalpana Has Improved Again in 2026
The most striking aspect of Kalpana’s 2026 campaign is that she has not simply maintained the level that carried her to successive Champions Day victories. She has demonstrated that she can compete successfully against the best middle-distance horses regardless of sex.
Her most important performance came in the King George VI and Queen Elizabeth Stakes at Ascot in July. Taking on colts and geldings in one of Britain’s premier open-age races, she produced another top-level performance to add a third Ascot Group 1 to her record.
Kalpana returned to competition against fillies and mares in the Yorkshire Oaks at York in August. The result was much closer than expected, with rapidly improving three-year-old Sparan Nua pushing her to a short head, but Kalpana still found enough to win after backing up relatively quickly from the King George.
That York result deserves more thought than a simple reading of the winning margin. Kalpana had produced a major effort at Ascot only 26 days earlier, while Sparan Nua was encountering a demanding mile and a half on slow ground and improved considerably on her previous form. Both horses emerged with useful evidence ahead of the autumn.
Sparan Nua Is One of the Improving Three-Year-Olds
Sparan Nua’s Yorkshire Oaks performance brought her firmly into the conversation for major autumn races. Jim Bolger’s filly started at 25/1 but pushed Kalpana all the way to the line, finishing only a short head behind the five-year-old with Minnie Hauk two and a half lengths further back in third.
That performance was particularly interesting because Sparan Nua had only begun her racing career a few months earlier. She had previously finished third in the Irish Oaks and then dropped to a mile before stepping back up substantially in distance at York.
Her improvement illustrates one of the central challenges when comparing three-year-old fillies with established older mares in October. A mare such as Kalpana brings a substantial body of proven Group 1 form, while a lightly raced three-year-old can still be developing quickly enough to improve beyond the level suggested by earlier performances.
Sparan Nua receives 6lb from the older mares under the 2026 weight-for-age conditions. That allowance does not make her automatically better treated, but it is an important part of the comparison if she takes her place at Ascot.
Thundering On Won the 2026 Oaks
Thundering On established herself among the leading three-year-old fillies when winning the Epsom Oaks in June. Joseph O’Brien’s filly handled the good-to-soft conditions particularly well and defeated Legacy Link by three and three-quarter lengths over the mile-and-a-half Classic distance.
Her next major assignment provided a very different challenge. She dropped back in trip and faced older opposition in the Pretty Polly Stakes, where she was unable to reproduce her Epsom performance. Rather than treating that defeat as evidence that the Oaks form was weak, it makes more sense to consider the different distance, ground and opposition.
Thundering On returned to winning form in September when taking the Blandford Stakes at the Curragh over ten furlongs, beating Lilt. That performance demonstrated that she possesses enough speed to operate below a mile and a half while reinforcing her position among the leading middle-distance fillies of her generation.
The principal question is now where she runs. The Arc has been part of the discussion, and what happens at Longchamp could determine whether a return to a mile and a half at Ascot is realistic less than two weeks later.
Johanna Walsh Adds Irish Oaks Form
Joseph O’Brien has another significant three-year-old in Johanna Walsh, winner of the Irish Oaks at the Curragh in July. She stepped into the leading role when Thundering On missed the race and produced an authoritative performance, beating Inis Mor with Sparan Nua third.
The Irish Oaks gives Johanna Walsh proven Group 1 form over the same broad distance as the Champions Fillies & Mares Stakes. Ascot is a different course from the Curragh, but the ability to sustain a strong performance over a mile and a half is clearly relevant.
Her subsequent Yorkshire Oaks run was less impressive, with Kalpana, Sparan Nua and Minnie Hauk all finishing ahead of her. That should form part of the assessment without erasing what she achieved at the Curragh. Horses do not reproduce exactly the same performance every time they race, and the task is to determine which run is most representative of the conditions they will face next.
If Johanna Walsh lines up at Ascot, she would also receive the 6lb three-year-old allowance from Kalpana and the other older mares.
Sunly Brings Strong French Form
Sunly represents another route into the race. Trained in France by Francis-Henri Graffard, she has been competing at Group 1 level and produced an eye-catching performance when third in the Prix Vermeille at Longchamp in September.
The bare finishing position does not tell the whole story. Sunly stumbled leaving the stalls and was then squeezed when trying to make her challenge, yet still finished third behind Friendly Soul and Pink Panthera. In circumstances where position and momentum mattered, she performed better than the result alone might suggest.
The Prix Vermeille is an obvious race to examine when assessing the Champions Fillies & Mares Stakes because it is another major fillies-and-mares contest over a mile and a half. It also takes place late enough in the season to provide relatively current evidence of a horse’s condition.
As always, the form needs context. Longchamp and Ascot are different courses, and the ground on Champions Day can create a substantially different test. The value of the Vermeille form will become clearer once we know which horses actually arrive at Ascot and under what conditions.
Lilt Remains Lightly Raced
Lilt has taken a different path and remains relatively inexperienced compared with many of the established Group 1 mares. William Haggas’s filly returned from a break in the Blandford Stakes at the Curragh in September and finished second to Thundering On.
That was only her fourth race, leaving open the prospect of further improvement as she gains experience. Her Curragh performance was also over ten furlongs, so stepping back up towards a mile and a half at Ascot would ask a different question.
Lightly raced horses can be difficult to compare with established performers because there is less evidence on which to base an assessment. That uncertainty should not automatically be interpreted positively or negatively. It simply means greater emphasis needs to be placed on the way the horse has raced, its pedigree, how strongly it has finished and whether the longer distance is likely to suit.
If Lilt remains in the field after confirmation, her profile will be quite different from Kalpana’s but potentially no less interesting.
Ascot’s Mile and a Half Is a Proper Stamina Test
The British Champions Fillies & Mares Stakes is run over 1 mile, 3 furlongs and 211 yards, effectively a mile and a half. At Ascot, that distance asks for more than simply proving a horse can stay twelve furlongs somewhere else.
The course is right-handed and galloping, while the finish places a sustained demand on horses after they turn for home. A filly or mare needs enough tactical speed to hold a useful position but also enough stamina to maintain its effort through the final stages.
This is particularly relevant when horses arrive from races over ten furlongs. A runner may possess the raw class to compete at Group 1 level but still need to prove that its racing style and stamina are suited to Ascot over the longer distance.
Our Ascot Racecourse guide explains the course and its major Flat races in more detail.
October Ground Can Change the Character of the Race
The old version of this page described testing ground and “bottomless stamina” as if they were permanent features of the race. Champions Day certainly can produce testing conditions, but recent renewals demonstrate why the going needs to be assessed each year rather than assumed in advance.
Kalpana won the 2025 race on good ground, while previous editions have been staged under much softer conditions. The difference matters because a strongly run mile and a half on testing ground places far greater emphasis on stamina than the same race on a sound surface.
Ground can also influence participation. Connections with a filly or mare whose best performances have come on quick ground may reconsider if prolonged rain arrives, particularly at the end of a long season. Conversely, horses with proven soft-ground form can become more interesting if the weather changes the nature of the race.
The latest Ascot going report should therefore form part of the analysis once race week arrives. Our horse racing going guide explains the different descriptions and why the effect of the surface varies between horses.
Pace Matters Over a Mile and a Half
Longer races are sometimes treated as though pace is less important than it is in sprints or mile contests. In reality, the tempo of a mile-and-a-half Group 1 can have a major influence on which horses are able to show their best form.
A steady early pace can favour horses with strong acceleration and leave proven stayers vulnerable in a sprint for home. A genuinely strong gallop places more emphasis on stamina and the ability to race efficiently before sustaining an effort through Ascot’s demanding finish.
Stable tactics can add another complication when trainers have several runners. A pacemaker may be used to ensure the race develops at a suitable tempo for a leading contender, but the rest of the field still has to decide how closely to follow.
Once the final declarations are known, our horse racing pace maps guide provides a useful framework for assessing how the race might develop.
The Arc Could Reshape the 2026 Field
The Prix de l’Arc de Triomphe takes place at Longchamp on Sunday 4 October, only 13 days before British Champions Day. That creates an obvious complication because several horses with Champions Fillies & Mares entries also have the class or connections to consider Paris.
Kalpana demonstrated in 2025 that running in both races is possible. She finished seventh in the Arc before returning to Ascot less than two weeks later and winning the Fillies & Mares Stakes comfortably. That does not mean every horse can handle the same schedule.
The effect of an Arc run depends on the individual horse, the ground, how hard it raced and how quickly it recovers. A filly involved in a demanding finish on testing ground at Longchamp faces a different recovery challenge from one that experiences a relatively straightforward race.
For that reason, the final 13 days before Champions Day can matter as much as form accumulated earlier in the summer.
Kalpana Won the 2024 Race as a Three-Year-Old
Kalpana’s first victory in the race came in 2024, when she was still progressing rapidly through her first season on the racecourse. She had been unraced at two and began the year winning a low-level race at Wolverhampton before developing into a Group 1 performer.
By Champions Day she had already demonstrated her ability over a mile and a half, but Ascot represented another step forward. Sent off favourite, she quickened clear to beat Wingspan, with Tiffany third.
That progression is worth remembering when assessing the current three-year-olds. Kalpana did not begin 2024 with the profile of an obvious future dual Group 1 winner. She improved as the season developed, which is exactly why lightly raced fillies such as Sparan Nua and Lilt need to be judged on what they may be becoming as well as what they have already achieved.
Kalpana Defended Her Title in 2025
The circumstances were very different twelve months later. Kalpana returned as an established older mare who had already competed successfully against some of Europe’s best middle-distance horses.
Her Arc run only 13 days earlier created a legitimate question about whether she would be at her best, but she answered it decisively. Racing prominently, she moved into the lead more than two furlongs out and comfortably held Estrange, with Quisisana third.
The victory also broke the sequence of three-year-olds that had dominated the race for much of the previous decade. Rather than treating that older age trend as a new system, the more useful conclusion is that an exceptional mare with proven Ascot form can remain extremely difficult for the younger generation to displace.
That is the question the 2026 field must answer again.
Recent British Champions Fillies & Mares Stakes Winners
- 2025: Kalpana, trained by Andrew Balding
- 2024: Kalpana, trained by Andrew Balding
- 2023: Poptronic, trained by Karl Burke
- 2022: Emily Upjohn, trained by John and Thady Gosden
- 2021: Eshaada, trained by Roger Varian
- 2020: Wonderful Tonight, trained by David Menuisier
- 2019: Star Catcher, trained by John Gosden
- 2018: Magical, trained by Aidan O’Brien
- 2017: Hydrangea, trained by Aidan O’Brien
- 2016: Journey, trained by John Gosden
- 2015: Simple Verse, trained by Ralph Beckett
- 2014: Madame Chiang, trained by David Simcock
- 2013: Seal Of Approval, trained by James Fanshawe
Three-year-olds have enjoyed significant success during the Group 1 era, but the recent results also demonstrate the danger of turning age into a rigid betting rule. Poptronic won as a four-year-old in 2023 before Kalpana won at three and then returned successfully at four. The individual horse, its form and the conditions of the race matter more than fitting a historical age pattern.
Magical Was an Outstanding 2018 Winner
Magical won the race as a three-year-old in 2018 for Aidan O’Brien and Ryan Moore, adding another important victory to a career that would eventually contain seven Group 1 successes.
Her achievements after the Fillies & Mares Stakes illustrate the quality the race can attract. Magical subsequently won the Champion Stakes at Ascot, twice won the Irish Champion Stakes and competed successfully against some of the best middle-distance horses in Europe and internationally.
She was not simply a specialist against her own sex. Like Kalpana in more recent seasons, Magical demonstrated that the strongest fillies and mares emerging from this race can compete at the highest level in open company.
That crossover is part of what makes the race particularly valuable when assessing the wider middle-distance division.
Oaks Winners Have a Strong Connection With the Race
Several Oaks winners have subsequently won this race, including Snow Bride, Ouija Board and Dancing Rain. Their success is understandable because both races test high-class fillies over approximately a mile and a half, although the circumstances are very different.
The Oaks is restricted to three-year-olds and takes place at Epsom in early June. By October, those fillies have had another four months to develop and must face older mares who bring greater experience and physical maturity.
Thundering On therefore follows a well-established route if she takes her chance in 2026. Her Oaks victory proves she can stay the distance at Classic level, but Ascot will ask whether she can reproduce that ability against a deeper cross-generational field at the end of the season.
That is a much more useful way to consider the Oaks connection than simply counting how many previous winners completed the double.
From the Princess Royal Stakes to British Champions Day
The race was first run in 1946 as the Princess Royal Stakes, with Mehmany winning the inaugural edition. It developed into an important middle-distance contest for fillies and mares and was classified as a Group 3 when the European Pattern system was introduced in 1971.
The race became the Pride Stakes in 2008 and was upgraded to Group 2. A more significant transformation followed in 2011 when it became part of the newly created British Champions Day at Ascot and adopted its current identity.
Group 1 status followed in 2013, establishing the race as Britain’s principal end-of-season championship contest for middle-distance fillies and mares.
Its history extends far beyond the current Champions Day era. Shebeen won in 1974 and 1975, while Crystal Capella became the second dual winner with victories in 2008 and 2010. Kalpana joined them in 2025 and now has the opportunity to become the first horse to win the race three times.
Leading Trainers and Jockeys
John Dunlop remains the most successful trainer in the history of the race with nine victories, while Sir Michael Stoute won it seven times. The latter’s record included Crystal Capella’s two victories before the race became part of British Champions Day.
Lester Piggott rode eight winners, the highest total achieved by any jockey. His victories stretched across several decades and reflect the long history of the contest before its modern Group 1 identity.
More recently, Ryan Moore and Frankie Dettori have both enjoyed repeated success in the race. Those records are an important part of its history, but trainer and jockey statistics should not be used in isolation when analysing the current renewal. The horse, current stable form, race conditions and tactical situation remain more relevant.
How to Analyse the 2026 Race
The final field should be the starting point for detailed analysis. Until confirmation and declarations have taken place, several of the most prominent entries could still head elsewhere and any assessment of pace or tactics remains provisional.
Once the runners are known, the most useful factors to examine are:
- Current Group 1 and Group 2 form
- Proven stamina over a mile and a half
- Ascot form
- Likely ground
- Expected pace
- Position in recent races
- Weight-for-age
- Progress of the three-year-olds
- How demanding each horse’s autumn campaign has been
- Recovery from the Arc or other recent races
- Previous form against the same opposition
Kalpana provides the established benchmark because she has already won this race twice and has strengthened her form again in 2026. The challenge is identifying whether one of the younger fillies has improved sufficiently to bridge the gap or whether another older mare arrives at Ascot under conditions that allow her to produce a career-best performance.
Our guide to analysing a horse race like a professional explains how to combine those factors rather than relying on a single statistic.
Historical Trends Need Context
The previous version of this page placed considerable emphasis on favourites, age patterns, ratings and the number of previous winners with Group-race form. Some of those statistics were interesting at the time, but they become less useful when presented as rules for future renewals.
Kalpana provides a good illustration. She contributed to the strong three-year-old record when winning in 2024 and then immediately weakened the same trend by returning successfully as an older mare in 2025.
The same problem applies to starting prices. A favourite winning does not prove favourites are advantaged, just as a double-figure-priced winner does not make the race inherently good for outsiders.
Historical evidence is most valuable when it tells us something about the demands of the race. Proven stamina, the ability to cope with Ascot, adaptability to autumn ground and current Group-level form all have a racing explanation behind them. Arbitrary sequences based on a small number of previous winners do not deserve the same weight.
British Champions Fillies & Mares Stakes Betting
There is already an ante-post market for the 2026 race, with Kalpana prominent after her outstanding season. At this stage, however, detailed price analysis is less useful than establishing which horses will actually run.
The Arc is an obvious complication. A horse’s price can change substantially depending on whether it goes to Longchamp, how it performs there and whether connections subsequently confirm Ascot. The market should look very different once confirmation takes place on 12 October.
The strongest approach is to analyse the likely field first and then compare that assessment with the available prices. Our guide to finding value bets in horse racing explains why identifying the most likely winner and identifying a worthwhile bet are separate decisions.

Ascot Tips on British Champions Day
The Fillies & Mares Stakes is scheduled before the three headline Group 1 races later on the card, so it can also provide useful evidence about the condition of the course. The distance means its pace and tactical demands differ from the sprint and mile races, but watching how horses travel and finish can still add information about the ground.
Conditions can change quickly in October, particularly if rain arrives during the afternoon. Going descriptions issued in the morning therefore need to be considered alongside what jockeys and trainers are reporting once racing begins.
Our Ascot betting tips page carries race-day selections and analysis across the card. Keeping those selections there allows this article to remain focused on the race itself, its contenders and the evidence that matters when assessing them.

British Champions Fillies & Mares Stakes 2026 Summary
The British Champions Fillies & Mares Stakes takes place at Ascot on Saturday 17 October 2026 and is currently scheduled for 2.40pm. The Group 1 is run over just short of a mile and a half and carries £500,000 in guaranteed prize money.
Kalpana is attempting to make history by winning the race for a third consecutive year. Her case is strengthened by an outstanding 2026 campaign that has included victory against open company in the King George at Ascot and another Group 1 success in the Yorkshire Oaks.
The younger generation provides considerable depth. Epsom Oaks winner Thundering On, Irish Oaks winner Johanna Walsh and rapidly improving Sparan Nua are among the three-year-olds capable of bringing strong mile-and-a-half form into the race, while Sunly and other older fillies and mares add further international strength.
The final field will not become clear until after the Arc and the confirmation stage on 12 October. Once it does, the race should be assessed through current form, proven stamina, Ascot experience, ground, pace, weight-for-age and the effect of each horse’s autumn campaign rather than the rigid historical betting trends previously associated with this page.
