Sky Sports Racing ambassador Hollie Doyle kicked off the first day of York’s Ebor Festival on Wednesday with a preview of the much‑anticipated showdown between Ombudsman and Constitution River. The versatile five‑year‑old Ombudsman, trained by John and Thady Gosden, is the favourite for the £1.5 million Juddmonte International Stakes (3.35) – a marquee race that tops the card on day one at York.

Ombudsman’s résumé has swelled dramatically since his triumph in this race a year ago; he has added a Group 1 victory in the Dubai Turf at Meydan and a win in the Prince of Wales’s Stakes at Royal Ascot, confirming his status as a world‑class middle‑distance performer. Across the paddock, Aidan O’Brien’s CONSTITUTION RIVER is positioned as the most intriguing challenger.

The son of Wootton Bassett, Constitution River has already demonstrated his class by capturing the French Derby and the Coral‑Eclipse, and he now receives a seven‑pound weight allowance for being two years younger than Ombudsman. While still developing, the colt possesses the versatility to match the Godolphin superstar on a day that promises tactical intrigue and a genuine test of stamina and speed. Juddmonte’s representative, Item, has a strong affinity for York, having secured Group 2 victories in both the Dante and the York Stakes. Despite being rated only two pounds below Constitution River, Item will need to dig deep to overcome the two leading contenders.

The race could become a classic duel, with the older, battle‑hardened Ombudsman pitted against the rising talent of Constitution River, each looking to assert dominance over the other. The festival also features the 250th running of the St Leger, for which Maltese Cross is a leading prospect after a convincing performance in the Sky Bet Great Voltigeur Stakes (3.00) at York – traditionally a trial for the Classic.

The writer’s husband, Tom Marquand, is optimistic that his horse can avenge a Derby defeat by Christmas Day in this Group 2 event, especially after a hard‑won Group 1 Grand Prix de Paris victory last month. Maltese Cross overcame numerous in‑race difficulties to finish a close second, suggesting he will relish the firm ground of the Knavesmire before stepping up in distance at Doncaster.

Christmas Day, another O’Brien trainee, failed to repeat his Epsom heroics in the Irish Derby, where stablemate Pierre Bonnard was a neck behind. Nevertheless, the colt remains a credible threat and could emerge as the primary Ballydoyle challenger to Maltese Cross.

In the Group 3 Tattersalls Acomb Stakes (2.25) at York, HAFFNER is the horse to beat despite a disappointing run in the Vintage Stakes at Goodwood. The O’Brien colt, who previously broke his maiden at Newmarket, now enjoys a favorable position behind the unbeaten Dr Rascal on the Downs, with less pressure to prove himself over the seven‑furlong distance.

Should HAFFNER underperform, Ed Walker’s Alfred Wallace offers an intriguing alternative. The son of the high‑class mare Snow Lantern earned a deserved Listed win at Ascot and may find the step up to a higher grade within his reach, potentially capitalising on any lapses from the front‑runners.

York’s sprint handicaps are notoriously tough to predict, but the writer makes a strong case for TOCA MADERA in the opening Hong Kong Jockey Club World Pool Handicap (1.50). David O’Meara’s gelding narrowly missed a better placing in the Stewards’ Cup at Goodwood and now benefits from an unchanged mark and the return of stable jockey Danny Tudhope. Drawn low in stall four, TOCA MADERA is well‑placed on the straight track, a configuration that suits the well‑supported The Man, who was second in the same race last year but lagged behind Toca Madera at Goodwood.

A cost‑effective alternative at longer odds could be Naana’s Sparkle, a gelding owned by Lemos de Souza. Naana’s Sparkle beat both TOCA MADERA and The Man in the Goodwood sprint and, with a middle draw, may receive a helpful tow into the race, offering value for punters. The writer also earmarks SMALL FRY as a "Hot Shot" after an unlucky run at the Goodwood Festival.

Despite a disappointing performance, the horse remains a contender in the Sky Bet Stayers Handicap (4.10) at York. Joseph O’Brien’s gelding, who was shuffled back at a crucial stage of the Summer Handicap but still finished a close second over 1m6f, could benefit from a four‑pound weight increase and seek compensation. The step up to two miles should suit Joseph’s son of Harzand, who stays well and will now be partnered with Ireland’s champion jockey Dylan Browne McMonagle for the first time. Meanwhile, Andrew Balding’s Shrimp Shady has emerged as a force in top staying handicaps and should not be overlooked.

After a strong second‑place finish at the Shergar Cup and a lucrative win at Newbury, Shrimp Shady is primed to tackle the demanding test of the Knavesmire. Overall, day one of the Ebor Festival promises a blend of seasoned champions and promising newcomers, each with distinct strengths and storylines. Whether Ombudsman can maintain his dominance, Constitution River can mature into a true rival, or one of the staying specialists can upset the odds, the Juddmonte International and the surrounding races will deliver a thrilling start to what is shaping up to be a memorable festival at York.
