Four days on the Knavesmire begin with the race most years crowned the best run in Britain, and this year the Juddmonte has earned the billing before a stall opens: the defending champion, a Royal Ascot winner rated the highest in training, against a three-year-old who took the Eclipse last month and has been beaten only once, on his debut. Around it sits everything that makes York in August the deepest week of the season, two cavalry-charge Heritage Handicaps, a stayers' marathon with no pace to run to, a juvenile Group 3 with a hot stable double, and a closing nursery that hides a Goodwood rematch regular readers will remember.
This guide reads all seven races through our model, and it works the way our coverage always works: the framing of every race is open to everyone, a free account unlocks the complete analysis on race morning, and members get the live data tables underneath, the same percentages, ratings and pace maps the dashboard runs, updating through the day. Along the way we explain the figures as we use them, because the point of these guides has never been tips. It is showing how data narrows twenty-two runners to two or three worth your attention, and letting you take the method anywhere.
How we read a race
Every horse in a race holds a TPR percentage and every field sums to 100, so the numbers read like the model’s own market. The engine chips show ability, current form and operating level; the sparkline is the last five race figures. Ten quick answers sit in the primer below, and the full walkthrough of every metric is in the complete data guide.
Hong Kong Jockey Club World Pool Handicap (Heritage Handicap)
5f89y | Class 2 Heritage Handicap | 21 runners
TPR percentages · every field sums to 100
Twenty-two sprinters, a Heritage Handicap pot, and a genuine collision between what the race looks like and what this course usually does with it. Our pace forecast for the opener is 11, among the highest numbers we have published for any race this season: a wall of confirmed early speed that ought, in theory, to burn itself out and hand the finish to the closers. York's own history argues back. Over nearly two thousand sprint runs on the Knavesmire, horses racing on the lead have outperformed expectation by 36 percent, while the hold-up runners have badly underperformed. When the model's percentages also spread as thinly as they do here, with just four points covering the top four, the data is telling you two things at once: keep your reading of the race wide, and think hard about who controls the front.
When a field this big flattens the percentages, we lean on the model's long-run behaviour rather than force a conviction it does not have. The top of the list still matters, because that is where the winners disproportionately come from, but the sensible play is to read the first handful as a group. Heading that group is Stratusnine, and the two numbers underneath him are the two we trust most in big sprint handicaps: a track figure of 130, meaning his best career form has come at this course, and a 150 last time out, meaning that form is current. Course plus currency is a rarer double than it sounds in a 22-runner cavalry charge, where most runners bring one or the other.
The strongest case for improvement in the field belongs to Corolla Point. Three weeks ago he won at Hamilton over this trip with the biggest single figure any of these produced last time, and stables matter here: his yard's one-month figure is running at 116 against a twelve-month baseline of 92, which in our data is the signature of an operation in the middle of a hot streak. He has answered the course question too, finishing third at York over five furlongs in May. The going figure completes the picture, a 136 on Good ground that leads this field, and if the phrase is new to you, a going figure simply isolates the best a horse has ever produced under today's exact conditions. Horses that tower on it, on the day's actual ground, win more than their price suggests.
Then the paradox that will decide the race. Four confirmed front-runners cannot all lead, and conventional reading says their war ruins them collectively. York's sprint course has spent two decades disagreeing: leading here pays, even in big fields, and it is the hold-up horses who historically pay the price of traffic and a short straight. That history is the argument for respecting Gold Star Hero, whose 148 last time is the best current figure among the speed horses, though his modest going figure on this ground is the honest caveat. It is also the argument against simply backing the closers into the teeth of the burn-up. In a race the model calls this open, that structural edge, front-end survival at a course that protects it, is as good a tiebreaker as any number we publish.
Stratusnine's course-and-currency double anchors an open race; Corolla Point is the improver from the hottest yard.

Tattersalls Acomb Stakes (Group 3)
7f | Class 1 Group 3 | 10 runners
TPR percentages · every field sums to 100
Eleven two-year-olds, thirty-one career runs between them, and a Group 3 that has launched more than its share of subsequent stars. Races like this are where our data works differently: with so little form on the page, the model leans on the things that project rather than the things that are proven, the sire's record with juveniles, the shape of a stable's season, the size of the figures earned in a handful of starts. One yard in form saddles two of the principals, the market's likely favourite has to fight another confirmed speedball for the early lead, and the biggest last-time figure in the race belongs to neither of them.
Reading an unexposed field starts with the sires, and this is a good place to explain the figure we lean on: the sire-juvenile number measures how a stallion's two-year-olds perform as a population, before their own form can speak. Only one runner here clears three figures on it, and it happens to be the one the model already tops: Haffner, a son of Justify whose 141 last time is as big a number as any of these has produced from a settled campaign of three runs. Add the stable, running at 119 for the month against a twelve-month baseline of 103, and three independent signals, pedigree, figure and yard, point at the same horse. That alignment is what a 21 percentage in an eleven-runner juvenile race looks like from the inside. The same hot yard also saddles Confucius, and a stable double in a race like this is information in itself, though five starts make him the more exposed half of the pair.
The model's percentages have a known personality trait worth understanding here: they underweight the barely-raced, because two runs simply cannot bank the evidence five can. That is the honest case for Vega King at each-way prices. From just two starts he has already matched Haffner's 141, and his sire profile reads solidly across every column we publish rather than spiking in one. Horses with that shape of record, big early figure, balanced pedigree, everything still to find, are precisely where the fifth-ranked percentage undersells the ceiling.
The dangers are two very different arguments. Clash Of Hearts brings the second-best percentage and the same front-running instincts as the favourite, which is the point: someone concedes that duel, and the winner of it may pay for the fight. And the biggest last-time figure in the race, a 182, belongs to Stardom Glory, earned winning at Chester in late June, with the reassurance of two second places at this track already in the book. Seven weeks off and a hold-up style into a four-forecast pace are the reasons the model holds him at 13 rather than higher, but of everything outside our two, his profile is the one the figures argue hardest for.
Haffner's pedigree, figure and yard all align; Vega King is the unexposed each-way angle.

Sky Bet Great Voltigeur Stakes (Group 2)
1m3f188y | Class 1 Group 2 | 6 runners
TPR percentages · every field sums to 100
Six runners, and the smallest field of the day carries the deepest form: the winner and the runner-up from Epsom's Derby meet again, with the Irish Derby third in between them on the racecard and a third Ballydoyle runner whose likely role is to make sure the gallop suits the other two. When the model puts a 42 on one horse, as it does here, it is about as close to conviction as our numbers ever get. The interest is less in whether the percentages are right than in what price the rematch angle offers against them.
There is no puzzle about the top of this race, so let's be straightforward about it. Christmas Day earned his 42 percentage the honest way: a Derby win in June, a second in the Irish equivalent three weeks later, and the two biggest conditions figures in the field for today's trip and ground. His 237 last time is the largest figure on tomorrow's entire card, and it was earned giving best only to a top-class rival at the Curragh. Ability 105, Operating 110: the ceiling and the current level agree, which in a three-year-old midsummer usually means the horse is still improving. At the prices this will be a short one, and the data says it should be.
The value question is really about second, and the model splits the Derby form pair in a way the market might not. Pierre Bonnard, third in the Irish Derby just behind our selection, holds 21 against Maltese Cross's 15, and the tiebreaker is the ground: his going figure of 190 on Good is the best in the race, the favourite's included. Maltese Cross, second in the Derby itself for the Haggas yard, is the proven Epsom form and no forlorn hope at 15, but he has to reverse Curragh placings with Pierre Bonnard on figures that lean the other way. And a practical note for reading the race live: Antigua, rated 87 in this company and a confirmed front-runner, is one of three here for the same connections, and if he sets the tempo it will not be an accident. A race run to suit the Ballydoyle principals is the final percentage in their favour that never appears in a table.
The Derby winner should confirm; Pierre Bonnard edges the Derby second on the ground figures.

Juddmonte International Stakes (Group 1)
1m2f56y | Class 1 Group 1 | 8 runners
TPR percentages · every field sums to 100
Most years the Juddmonte is billed as the best race run in Britain, and most years the billing struggles to live up to itself. Not tomorrow. The horse who won this race twelve months ago comes back as a Royal Ascot winner with the highest official rating in training, and the thing sent to beat him has lost just once, on his racecourse debut, winning all five since including last month's Eclipse, and meets his elder on weight-for-age terms. Between them on our numbers sits a Group 1 winner whose two best career figures were both earned on this track, and lurking outside the numbers entirely is a French raider our database, honestly, cannot see. The model has made its call, and made it emphatically. Championship days are why the data exists.
Begin with what a 38 percentage means in a Group 1 of this depth: it is the model saying one horse holds the aces in almost every suit, and Ombudsman genuinely does. He is the defending champion, successful over tomorrow's course and distance in this race last August. His going figure of 194 on Good ground is the best in the field by nearly thirty points. His Ability and Operating figures, 114 and 116, say a horse already at the top is still nudging upward at five, and his season reads won at Sandown, won at Royal Ascot. About the only quibble the data can raise is that his latest figure, a 164, is below the 221 he posted the time before, and a two-race view of any top horse will always breathe like that.
The challenge is real, though, and it is worth being precise about why. Constitution River has been beaten exactly once, on his debut at Newmarket last July, and has won all five races since. One of those wins came at Chantilly and does not appear in our figures, because French form sits outside our database, the same honesty that applies to the raider below. His Eclipse win last month produced the best latest-run figure in tomorrow's field, and his 214 at this distance is the kind of number that wins Internationals in most seasons. He also carries the three-year-old's allowance, and history is kinder to his generation in this race than the market sometimes remembers. The model still prefers the champion by two clear classes of percentage, 38 against 19, and the reason is breadth: the younger horse's case rests almost entirely on two figures, where Ombudsman's case is made in every column.
Almaqam is the third force and the local specialist. Both of his two biggest career figures were earned on the Knavesmire, his track figure of 196 tops the field, and he arrives a Group 1 winner from the Curragh in May. What the data holds against him is the freshest evidence: fourth behind Ombudsman at Ascot when the pair last met, and a latest figure some way below his peak. A returning York specialist against proven recent inferiority is a genuine each-way argument, not a winning one.
And a word on the horse we cannot rate, because pretending otherwise would be worse. Zaydann's form is entirely French, which means every figure we publish for him tomorrow reads zero, and his 1 percentage is an absence of evidence rather than a verdict. Our model has a known blind spot with overseas form and we would rather tell you that than dress it up. Respect the market on him: if he is shorter than his blank columns suggest he should be, other people know something our database does not.
The defending champion's case is made in every column; the unbeaten Eclipse winner is the live threat on weight-for-age.

Sky Bet Stayers Handicap (Heritage Handicap)

TPR percentages · every field sums to 100
Two miles, seventeen runners, and a pace forecast of just 2, the lowest of the day. Stamina races with no pace are a lovely paradox: the trip says endurance, the tempo says sprint finish, and the result usually belongs to whoever is placed when the dash begins. Our model's top pick arrives with a complication the percentages keep quiet about, one in-form yard runs a horse for each version of the race, and the in-form progressive in the field is stepping into the unknown on trip. A proper puzzle, and the shape of it matters more than any single number.
Start with the tactics, because a crawl rewrites the form book. When almost nobody in a race wants to lead, the field walks and sprints, position beats stamina, and the horses ridden prominently get first run at the business end. On that reading and on the percentages the race belongs to Manxman: the model's clear top pick, a prominent racer in the race that rewards exactly that, from a yard running seventeen points above its yearly baseline, off a mark just two pounds above his last win. One thing you should know before the market tells you: he has not raced since September, eleven months ago. We flag it because absence is the kind of fact a percentage quietly absorbs rather than advertises, and a reader deserves both halves: stables this hot do not bring one back to a Heritage Handicap undercooked, and fresh horses in slowly-run races are forgiven their rustiness more than in any other kind. The model has kept its faith; so, with eyes open, do we.
The dependable alternative is Valedictory, whose summer needs no asterisk at all: won at Goodwood in May, won at Newmarket in July, ran to his career-high mark three weeks ago. Mid-division suits the shape, his ground figure is second-best in the field, and the only question is a first try at two miles, softened considerably by a tempo likely to make the trip play shorter than the racecard says. Of the rest, the Crisford yard also saddles Boatswain, whose 168, the field's biggest figure, was earned winning over this sort of trip at Southwell in July, but whose hold-up style is a tax in the day's slowest-forecast race. And for the tutorial-minded, compare two numbers: Prydwen runs four pounds above his last winning mark, Small Fry thirteen. That gap is the OR delta, the distance between the mark a horse carries and the one it last won off, and across our database the small end of it is where handicaps get won.
Manxman fits the crawl and the model keeps faith through the absence; Valedictory is the in-form insurance.

Irish Thoroughbred Marketing Handicap (Heritage Handicap)
5f | Class 2 Heritage Handicap | 19 runners
TPR percentages · every field sums to 100
Nineteen sprinters and a pace forecast of 16, the highest number our model has ever attached to a race in these guides. If the opener asks what happens when too much speed meets York's five furlongs, this one asks it at full volume: seven of the first nine on our list are confirmed front-runners, and the percentages spread just seventeen, ten, seven across the top three. When the model declines to commit, that is not the data failing, it is the data being honest, and the reading below is built accordingly: a race to attack with a wide net and a clear head about which speed survives.
A field this flat on the percentages is a lottery with weighted tickets, and the job is simply to hold the heaviest ones. The heaviest belongs to Naanas Shadow, and it is one of the most complete sprint-handicap profiles on the whole card: she won at Goodwood four weeks ago, she won at York over this exact trip in June, and her stable is running twenty points above its yearly baseline. Course, currency and yard, all banked. Two debits keep her percentage at seventeen rather than something grander: a mark now eight pounds above the one she last won from, and membership of the seven-strong crowd that wants the early lead. On the second of those, remember the opener's lesson: this track forgives forwardness more than any other bias in our database, and a filly who has already won a York cavalry charge from that running style has answered the question once.
The boldest number in the race belongs to Baker Blue, and it is forty-seven points clear of anything else in the latest-run column: a 178, produced finishing third at Pontefract on Sunday, two days before this. A quick back-up divides opinion in every era of the game. Read generously, it is a horse in the form of its life being struck while hot; read cautiously, it is a hard race still in the legs, and a stable whose wider numbers are cold does not settle the argument for us. The figure is real and enormous, which is why it earns the second bold, and the yard is why the each-way terms matter more here than usual. Of the rest, Schrodingers Cat owns the smart tactical profile, prominent without being suicidal and second at this track in June, but he is twelve pounds above his last winning mark and that measure, as the previous race showed, is rarely generous. And if you want the pure data quirk at a price, Dolos Dream's 168 on this ground is far the best going figure in the field, attached to a horse the handicapper has otherwise given up on. Burn-ups occasionally belong to exactly that kind of survivor.
Naanas Shadow's course-currency-yard treble tops the lottery; Baker Blue's giant figure earns the second bold despite the quick back-up.

Sky Bet Nursery Handicap
6f | Class 2 Nursery | 18 runners
TPR percentages · every field sums to 100
The day closes with a nursery, a handicap for two-year-olds, which is the purest contest on any card between the handicapper's guesswork and everybody else's. With babies, the official assessor is rating a handful of runs and a lot of projection. So are we, but our projection carries figures, and in a field of twenty-two they point two very different stories at the top: a maiden the clock adores, and a filly who has stopped being beaten. There is also a Goodwood rematch buried in here that regular readers of our festival coverage will remember.
Nurseries reward the horse whose ability the handicapper cannot yet see, and the data's candidate is The Dancing Pirate, despite a form line that reads fourth, fourth, second, seventh without a win. The figures tell a different story to the placings: a ground figure of 175 on Good, far the best in this field, and a 153 at the trip, both earned running Chester to within a neck of victory in June. As for that latest seventh at Goodwood, we carried him strongly in our Day Four guide, a 20 percentage in a race of this same kind, and the bare result deserves its asterisk: on a day when the stand-side rail was the place to be, he was obliged to launch his effort away from it. Runs like that are exactly what the conditions figures are for, they remember what the finishing position forgets. An 83 mark for a horse with these numbers is the handicapper still pricing the form line, and prominent tactics into a nine-forecast pace complete a very live profile.
The counter-argument has won its last three. Havana Sprite took a maiden at Bath in June and has since won twice at Newmarket in nurseries just like this, the latest a fortnight ago off a mark four pounds lower than tomorrow's, producing a 161 that leads the field's current-form column by thirty points. Hat-trick two-year-olds are how progressive juveniles stay ahead of the assessor, right up until the mark catches them, and the race really is the question of which happens first: our maiden's ceiling or her rising floor. Completing the Goodwood thread, Dubai Champion, second in that Day Four nursery our selection sank in, brings figures of 151 and 173 and a York run already banked from May; a cold yard is the reason he wears no bold. And the each-way wildcard from the in-form stable is God Given Talent, a 144 last time from the hottest yard in the race, though his is a one-spike profile where our two principals bring bodies of evidence.
The clock backs the maiden over the hat-trick filly; the Goodwood excuse is real and receipted.

Where the data landed, race by race.
The data, explained
New to the numbers? Quick answers below, and the full walkthrough of every metric lives in the complete EquiAnalytix data guide.
What is TPR?
TPR (Total Performance Rating) is EquiAnalytix's proprietary rating, built from a database of more than 836,000 runs. Every horse's number is derived from race times adjusted for class, going, pace and race shape, so it measures what a horse actually did rather than what the handicapper thinks of it.
What does the percentage mean?
Every horse in a race holds a TPR percentage and every field sums to 100, so the numbers read like the model's own market. Across our whole database, 73 percent of winners come from our top four ranked horses, which is why the top of the list is where every read begins.
What are Ability and Operating?
Ability is the ceiling: the underlying class a horse has shown at its very best. Operating is the now: the level it is producing this season, Ability plus current form. When both agree at a high level, as with the best horses on this card, the model reads a horse at its peak.
What are the conditions figures?
Going, track and distance figures isolate a horse's best performances under today's exact conditions. A high going figure on Good ground matters far more than a career best earned in a bog, and a big track figure says this course specifically brings out the horse's best. They also remember runs that finishing positions forget, as with beaten horses who met track bias.
What is the pace forecast?
Each runner's early-position style is profiled from its history, and the race pace forecast adds them up. High numbers mean contested speed and favour those who can sit just off it; very low numbers mean a crawl and favour the prominent. At York specifically, two decades of data say front-runners outperform expectation, especially in sprints.
What is the OR delta?
The gap between the official mark a horse carries today and the mark it last won from. Small numbers mean the handicapper has not yet punished the horse for winning; big numbers mean it must be better than ever to win again. Across our database, handicaps disproportionately go to the small end of the scale.
Why do some runners show zeros?
Zeros mean absence of evidence, not a verdict. A horse whose form is entirely overseas, like a French raider, sits outside our database, and we would rather tell you the model cannot see it than dress a blank up as an assessment.
