Sandown Park racecourse guideStablebet model (pre-race estimated win chances)
Sandown Park 15:35 · Coral-Eclipse (Group 1) · Class 1 · 1m1f209y
Pre-race estimate. Published 4 July 2026, before the off. This is what the model made of the race beforehand, kept as a record. It was never published as a tip.
The model rated Constitution River its most likely winner at 18%, ahead of Gethin (18%) and Hawk Mountain (17%). It read as a competitive, open race with no dominant runner.
| Horse | SP | Model chance | Market | vs Market |
|---|---|---|---|---|
| Constitution River R L Moore / A P O'Brien | 1.83 | 18.1% | 47.5% | Market 29.4pp shorter |
| Gethin James Doyle / Owen Burrows | 5.00 | 17.9% | 17.4% | Market 0.5pp longer |
| Hawk Mountain Wayne Lordan / A P O'Brien | 7.00 | 17.3% | 12.4% | Market 4.8pp longer |
| Saddadd Ray Dawson / R Varian | 8.00 | 15.7% | 10.9% | Market 4.9pp longer |
| A Boy Named Susie Oisin Murphy / Donnacha O'Brien | 9.00 | 10.9% | 9.7% | Market 1.2pp longer |
| Flushing Meadows S M Levey / A P O'Brien | 101.00 | 10.2% | 0.9% | Market 9.3pp longer |
| King's Gambit J P Spencer / Harry Charlton | 67.00 | 9.9% | 1.3% | Market 8.6pp longer |
These were the model's estimated win chances going into the race, not tips. The model is calibrated to real results (when it says 25%, about 25% win) but it does not beat the market, so read it as an independent second opinion on the race. See how accurate it is →
Coral-Eclipse 2026: the first summer collision of the generations
The race has run. Constitution River (8/11f) won the 2026 Coral-Eclipse for Aidan O'Brien and Ryan Moore, beating A Boy Named Susie by three lengths. See the full result and finishing order.
Saturday 4 July 2026, around 15:35 BST. Sandown Park. Coral-Eclipse, Group 1, 1 mile 2 furlongs, three-year-olds and up, £1,000,000 guaranteed.
The Eclipse is the first big mid-summer test where the season's leading three-year-olds take on their established elders over a mile and a quarter, and it has launched more than a few champions on their way. First run in 1886 and named after the great unbeaten Eclipse, it is one of the most historic races in the calendar and, with a seven-figure pot, one of the most valuable.
This year's heat carries real Royal Ascot form. Among the early entries are Ombudsman, fresh from retaining his Prince of Wales's Stakes crown, the Coronation Stakes winner Precise, the Prince of Wales's runner-up Minnie Hauk, and Almaqam — all of whom ran at the Royal meeting. They are set to be joined by the older French-trained standard-bearer Calandagan and a clutch of Ballydoyle three-year-olds taking the weight-for-age allowance.
A quick word on what follows. At the time of writing the race is at the entry stage (34 entered), not the final field — the runners, riders and the draw are fixed at the 48-hour declaration stage (around Thursday 2 July). Treat every name below as a possible runner, and the prices as a guide that will move; we will update this page as the field firms up. Nothing here is a tip.

The race and the Sandown test
The Coral-Eclipse is run on Sandown Park's round course over 1 mile 2 furlongs — a stiff, galloping test that asks a different question from the flat, fast tracks where many of these horses earned their reputations. The defining feature is the uphill finish: the last three furlongs climb to the line, so a horse that travels strongly but stops climbing the hill is found out, while one that stays every yard of the trip is rewarded. It tends to be a true test of a proper middle-distance horse rather than a sprint-finish lottery.
The mile-and-a-quarter trip is the other key. It sits between the mile of the St James's Palace and Sussex types and the mile-and-a-half of the Derby and King George, and it suits horses with both a turn of foot and the stamina to use it off a strong gallop. Several of the likely runners are stepping up or coming back in trip to find their optimum, which is part of what makes the race so informative about the rest of the season.
The headline storyline every year is three-year-olds versus older horses. The Classic generation receive a weight-for-age allowance from their elders — a few pounds that reflects their relative immaturity in early July — and in some years that allowance has been decisive, in others the proven older horse has simply been too good. With Royal Ascot's winners and placed horses among the entries this time, the race shapes up as a genuine clash of the best older milers-and-a-quarter against the pick of this season's emerging Classic types.
Because the Eclipse so often sets up the second half of the season — pointing horses towards the King George, the Juddmonte International and the autumn Group 1s — it is worth watching as much for what it tells us as for the result on the day.
Trends and angles to weigh
A few durable patterns are worth holding in mind for the Eclipse — these are tendencies, not rules, and the form of the actual declared field always matters more than any angle:
- Class tends to tell. This is a championship Group 1, not a handicap: the horses with the strongest proven top-level form generally run their race. Upsets happen, but the Eclipse is rarely won by a horse without genuine Group-class form to its name.
- You have to stay the trip and handle the hill. The uphill finish over 1m2f punishes non-stayers and one-paced milers. Horses with a proven, strong-galloping mile-and-a-quarter (or a mile-and-a-half) profile are on surer ground than those dropping back from further on speed alone.
- The weight-for-age allowance is a real edge for the right three-year-old — but only for one good enough to use it. In some seasons the Classic generation has dominated; in others the established older horse has been simply better. Judge the individual, not the age bracket.
- Recent running lines count double in early July. Many of the likely runners contested Royal Ascot a fortnight earlier, so the Royal Ascot 2026 results are the freshest and most reliable form lines into this race — particularly the Prince of Wales's and the Coronation.
We have deliberately not quoted a "winners by age" or "winning favourites" tally here, because the renewal-by-renewal record is best read against the actual field once it is declared. When the 48-hour declarations are out we will line the genuine runners up against these angles. For the model's own probability estimate on each declared runner, see the AI Race Predictor read nearer the day.
For reference, here is the recent roll of honour — the source-verified pattern the angles above are drawn from:
Coral-Eclipse (Eclipse Stakes): Recent Winners
Group 1 · 1m 1f 209y · 3yo+ (fillies & mares 3lb allowance) · Sandown · Early July
| Year | Winner | Age | SP | Jockey | Trainer |
|---|---|---|---|---|---|
| 2026 | Constitution River | 3 | 8/11 | Ryan Moore | Aidan O'Brien |
| 2025 | Delacroix | 3 | — | Ryan Moore | Aidan O'Brien |
| 2024 | City of Troy | 3 | — | Ryan Moore | Aidan O'Brien |
| 2023 | Paddington | 3 | — | Ryan Moore | Aidan O'Brien |
| 2022 | Vadeni | 3 | — | Christophe Soumillon | Jean-Claude Rouget |
| 2021 | St Mark's Basilica | 3 | — | Ryan Moore | Aidan O'Brien |
| 2020 | Ghaiyyath | 5 | — | William Buick | Charlie Appleby |
| 2019 | Enable | 5 | — | Frankie Dettori | John Gosden |
| 2018 | Roaring Lion | 3 | — | Oisin Murphy | John Gosden |
| 2017 | Ulysses | 4 | — | Jim Crowley | Sir Michael Stoute |
Trends
- Three-year-olds taking the weight-for-age allowance dominate recent runnings, though top older horses (Enable, Ghaiyyath, Ulysses) also win it.
- Strong Classic and Royal Ascot form plus proven stamina up the Sandown hill are the key pointers; Ballydoyle sets the standard.

The likely field
These are among the 34 entries at the five-day stage — not the final field. Runners, riders and the draw are confirmed at the 48-hour declaration (around Thursday 2 July), and several of these will not take their chance. We will update this list when the field is declared.
The older brigade
Calandagan heads the established older horses on most early lists — a proven, high-cruising-speed performer around this trip whose consistent top-level profile makes him a natural standard-bearer for the elders. Ombudsman arrives in form, having retained his Prince of Wales's Stakes crown at Royal Ascot — read how that played out in our Ombudsman v Almaqam result. Almaqam, the Tattersalls Gold Cup winner who finished fourth behind Ombudsman in that Prince of Wales's, is also entered and would have obvious claims on a going-right day.
The fillies
Minnie Hauk, second to Ombudsman in the Prince of Wales's, is among the most interesting entries — a filly with proven Group 1-placed form at the trip. Precise, who justified favouritism in the Coronation Stakes, would be stepping up from a mile to a mile-and-a-quarter and out of her own age-and-sex bracket, a big ask but the mark of a genuinely smart filly. Diamond Necklace is the other leading filly on the list.
The Classic generation
Aidan O'Brien's Ballydoyle yard holds several entries among the three-year-olds, including Constitution River and Hawk Mountain, taking the weight-for-age allowance from their elders. As ever with the powerful stables, expect the final hand to be revealed late; the three-year-old that lines up could be the one to fear if the allowance bites.
The shape of the race — and the market — will firm up considerably at the 48-hour stage. For an independent, calibrated probability on each declared runner, see the AI Race Predictor read closer to raceday.
Betting angles and where to watch
A few honest pointers rather than tips. With the field not yet declared, the sensible approach is to wait for the 48-hour confirmations and the going before committing — Sandown's mile-and-a-quarter rewards a proven stayer who handles the hill, so weight that more heavily than a flashy turn of foot on a flatter track.
- The Royal Ascot form is the strongest line in. The Prince of Wales's and the Coronation produced the freshest Group 1 collateral form; lean on horses who ran well there over those returning from longer breaks or stepping sharply up or down in trip.
- Respect the weight-for-age question both ways. A top three-year-old with the allowance is dangerous, but only if it is genuinely good enough — don't back an age bracket, back a horse.
- In a small, classy field, each-way value is usually thin. Championship Group 1s often go off with single-figure runners, so the place terms rarely pay as they do in the big handicaps; judge the win bet on its merits.
