Every Breeders' Cup, American horseplayers face the same uncomfortable problem.
A European horse shows up with impressive credentials, an elite trainer, a world-class jockey—and past performances that don't tell us nearly as much as we'd like.
Some players dismiss the horse because they can't make sense of the foreign form. Others automatically include every European runner because of their reputation.
Neither approach is particularly satisfying. And history tells us we certainly can't afford to ignore them.
The Europeans Have Earned Our Respect
The numbers are difficult to argue with.
From 2016 through 2025, European-trained horses won 37 of 68 Breeders' Cup turf races. More remarkably, they won nine of the ten Breeders' Cup Turf championships during that period.
When the Breeders' Cup last visited Keeneland in 2022, European-trained runners captured six of the seven turf races.
Last year at Del Mar, they won five of seven, including the Turf, Mile, Filly & Mare Turf, Juvenile Turf and Juvenile Fillies Turf.
And these aren't always short-priced favorites. In 2025, Willie Mullins sent out Ethical Diamond to win the $5 million Breeders' Cup Turf, returning $57.40 for a $2 win wager.
The dominance isn't universal. Europeans won only two of the ten Turf Sprints from 2016 through 2025. The edge is particularly pronounced in longer turf races.
But the larger point is unmistakable:
European-trained horses have been a defining force in Breeders' Cup turf racing.
The Past Performance Problem
Here's where things get interesting for the handicapper.
We're accustomed to a fairly standardized set of information: speed figures, running positions, fractions, class levels and surfaces that we can compare across familiar American tracks.
Then we open the past performances for a horse arriving from Ascot, Longchamp, Leopardstown or Newmarket.
The information isn't necessarily absent. International form and specialized ratings are available. But what appears in conventional American past performances can be considerably thinner, and the available information isn't always directly comparable.
European racecourses differ dramatically in configuration, terrain and racing conditions. The racing itself can unfold differently.
A final time from an undulating European course doesn't translate neatly into a time at Keeneland. Neither does a finishing position tell the entire story about the quality of the competition or the performance required.
And an impressive European Group 1 performance still has to be considered in the context of an American Grade 1 field.
The problem isn't simply missing data. It's understanding what the available evidence actually means.
That's a much harder assignment.
Different Racing Styles, Different Demands
European turf racing frequently emphasizes rhythm, patience and the ability to produce a sustained finishing run.
Many races develop at a more measured early pace before turning into a serious test of acceleration.
American racing can present a different challenge.
The turns, early positioning, race tempo and traffic associated with a relatively compact American oval can change the demands considerably.
A European runner accustomed to settling comfortably before unleashing a powerful finishing kick may find that the race develops differently at Keeneland.
Of course, not every European horse is a deep closer. Some possess excellent tactical speed and can adapt to different race shapes.
The challenge is distinguishing a horse with genuine transferable ability from one whose apparent strengths may be less effective under unfamiliar conditions.
And Then There's the Turf Itself
Ground conditions are another major consideration.
European horses regularly compete on turf ranging from firm to very soft. Some perform their best when there's considerable give in the ground. Others are perfectly comfortable on faster surfaces.
That's an important distinction.
European doesn't automatically mean soft-ground specialist.
Consider Gezora, the French-trained winner of the 2025 Breeders' Cup Filly & Mare Turf. She defeated a strong American rival, She Feels Pretty, on a firm turf course at Del Mar.
The question isn't whether a horse comes from Europe. It's whether the conditions it encounters are likely to suit the abilities it has demonstrated.
That uncertainty can make these international matchups fascinating—and frustrating.
The People Behind the Horses Matter
European success also reflects the remarkable concentration of elite training talent.
Aidan O'Brien and Charlie Appleby have established extraordinary Breeders' Cup records. Trainers such as Francis-Henri Graffard and Willie Mullins have also demonstrated their ability to succeed on this stage.
The jockeys are equally accomplished.
Ryan Moore, William Buick and other leading international riders bring extensive experience handling high-class turf horses across very different racecourses.
These are not inexperienced connections taking an experimental trip overseas.
They're accomplished professionals who understand the demands of international competition.
But even the best trainer and jockey cannot eliminate the uncertainty of a horse encountering different conditions.
Elite connections are a reason to pay attention, not a substitute for handicapping.
What Does This Mean for the Horseplayer?
For me, the lesson is fairly straightforward.
We can't dismiss European runners because their form is unfamiliar. Their historical success makes that a costly proposition.
But blindly backing them because they're European isn't much better.
The real challenge is developing a credible understanding of their ability despite differences in the racing environments and the information available.
At HCRALabs, these are precisely the types of problems that make quantitative race intelligence both challenging and worthwhile.
The objective isn't to manufacture confidence when the evidence is incomplete. It's to distinguish what we can reasonably trust from what remains uncertain.
And importantly, even identifying the most talented horse doesn't automatically establish that the horse is a good bet at the available odds.
As Breeders' Cup week arrives at Keeneland, the European turf runners deserve considerable respect.
They've earned it.
But their presence also reminds us that handicapping isn't simply a matter of reading numbers from a page.
Sometimes the most difficult part is understanding what the numbers don't tell us.
And sometimes, recognizing that uncertainty is itself an important handicapping decision.
Make better bets. Skip bad ones.
