The landscape of the Group 1 Juddmonte Irish Oaks has undergone a significant transformation following the eleventh-hour withdrawal of Thundering On, a highly regarded daughter of Frankel owned by Shapoor Mistry. The filly, who had been positioned as a leading contender for the third Classic of the Irish season, was officially removed from the lineup on Saturday morning. Reports from the stable indicated that the filly was "off her feed," a condition that, while common in high-performance equine athletes, necessitates immediate withdrawal from elite-level competition where peak physical condition is a prerequisite for safety and performance.
This development has sent shockwaves through the betting markets and necessitated a strategic reshuffling among the jockey ranks. With Thundering On absent, the spotlight intensifies on Earth Shot, the Ribblesdale Stakes winner representing Wathnan Racing, who now assumes the mantle of the clear favorite. Furthermore, the withdrawal has prompted a change in riding assignments, with Dylan Browne McMonagle now expected to partner with Johanna Walsh, a talented filly trained by Joseph O’Brien who finished as the runner-up to Earth Shot during their previous encounter at Royal Ascot.
A Sudden Turn of Events at The Curragh
The Juddmonte Irish Oaks, contested over a distance of one mile and four furlongs at the historic Curragh racecourse, is the premier event for three-year-old fillies in Ireland. The late withdrawal of a horse of Thundering On’s caliber is a rare and disappointing occurrence for fans and connections alike. Trained to peak for this specific mid-summer highlight, Thundering On represented the elite bloodlines of her sire, Frankel, and the ambitious racing interests of Shapoor Mistry.
Veterinary experts note that a horse being "off its feed" can be a precursor to various minor ailments, such as a low-grade respiratory infection or general lethargy, which would prevent an athlete from performing at the 100% capacity required for a Group 1 Classic. In the interest of horse welfare, the decision to withdraw is the only logical course of action, despite the prestige of the event. The timing is particularly poignant, occurring on the very morning of the race, leaving little time for the remaining participants to adjust their tactical approaches to a field that has lost one of its primary pacesetters or closers.
The Rise of Earth Shot: A New Market Leader
With the departure of Thundering On, the focus shifts squarely to Earth Shot. Owned by the burgeoning powerhouse Wathnan Racing and sired by Time Test, Earth Shot has seen her stock rise meteorically since her impressive victory in the G2 Ribblesdale Stakes at Royal Ascot. That performance demonstrated not only her stamina over the twelve-furlong trip but also her ability to handle the pressure of a high-capacity field.
Earth Shot’s victory at Ascot was characterized by a sustained late surge, a trait that translates well to the long, demanding home straight of The Curragh. The Irish Oaks often serves as a "decider" for the top-tier fillies that competed in the English equivalent at Epsom or the Ribblesdale at Ascot. For Earth Shot, this race represents an opportunity to cement her status as the leading three-year-old filly in Europe. The Wathnan Racing team, which has invested heavily in top-tier bloodstock over the last twenty-four months, views this Classic as a vital milestone in their international campaign.
Tactical Adjustments: Johanna Walsh and Dylan Browne McMonagle
The withdrawal of Thundering On has directly impacted the plans for jockey Dylan Browne McMonagle. Originally slated to ride elsewhere or potentially remaining unattached to a top-three favorite, McMonagle is now poised to reunite with Johanna Walsh. Trained by Joseph O’Brien, Johanna Walsh is a daughter of the legendary Sea The Stars, a sire renowned for producing durable, high-class stayers.
Johanna Walsh’s performance in the Ribblesdale Stakes was noteworthy; she chased Earth Shot home to finish second, proving she belongs at this level. The switch to McMonagle, one of Ireland’s most tactically astute young riders, provides Joseph O’Brien with a potent weapon in his quest to secure another Classic title. Johanna Walsh possesses a pedigree that suggests she will relish the galloping nature of The Curragh, and the rematch between her and Earth Shot is now the defining narrative of the race.
Pedigree Analysis and Performance History
The Juddmonte Irish Oaks is as much a test of breeding as it is of training. The horses involved in the 2024 edition represent some of the finest genetic lines in the Thoroughbred world.
The Influence of Frankel and Sea The Stars
Thundering On’s sire, Frankel, has dominated the European sire standings for several years. His progeny are known for their high cruising speeds and relentless finishing power. While her absence is a loss for the race’s depth, the presence of Sea The Stars through Johanna Walsh ensures that the "Galileo line" is still well-represented. Sea The Stars, a half-brother to Galileo, has a remarkable record at The Curragh, having won the Irish Champion Stakes and the Irish Derby during his own illustrious career.
Time Test and the Next Generation
Earth Shot’s sire, Time Test, represents a slightly different branch of the pedigree tree. As a son of Dubawi, Time Test has been noted for producing horses with great acceleration. Earth Shot’s success in the Ribblesdale was a significant "black type" boost for her sire, and an Irish Oaks victory would catapult him into the top tier of commercial stallions.
The Significance of the Juddmonte Irish Oaks
Established in 1895, the Irish Oaks has a storied history of identifying the greatest fillies in the sport. It is the female equivalent of the Irish Derby and carries a massive purse, alongside immense prestige for future broodmare value. Past winners include legendary names such as Enable (2017), Snowfall (2021), and Ouija Board (2004).
Winning the Irish Oaks is often a springboard to the Prix de l’Arc de Triomphe or the Breeders’ Cup Filly & Mare Turf. The race is sponsored by Juddmonte, the international breeding operation founded by the late Prince Khalid Abdullah, which adds a layer of significance to the event. Juddmonte’s sponsorship has ensured that the race remains a focal point of the European summer season, attracting the best trainers from Ireland, Great Britain, and occasionally France.
The Curragh: A Testing Ground for Excellence
The Curragh is widely regarded as one of the fairest racecourses in the world. Its sweeping turns and long uphill finish ensure that the best horse almost always wins, with minimal interference from "track bias" or luck in the draw. The ground conditions for this year’s Oaks are reported as Good to Firm, which will favor those with a high-action stride and the ability to maintain speed over a distance.
For Earth Shot and Johanna Walsh, the conditions are ideal. Both fillies showed at Royal Ascot that they can handle a fast surface. The twelve-furlong start at The Curragh allows the field to settle into a rhythm before the turn into the straight, making it a true test of stamina. Without Thundering On, who was expected to sit close to the lead, the early tempo of the race may be slightly more sedate, potentially turning the finish into a sprint over the final three furlongs.
Official Responses and Connections
While official statements from the Shapoor Mistry camp have been brief, the sentiment is one of "safety first." In modern horse racing, the scrutiny on equine health is at an all-time high. Trainers like Joseph O’Brien and William Haggas (trainer of Earth Shot) operate under rigorous protocols where any deviation from a horse’s normal behavior results in a scratch.
Joseph O’Brien, speaking on his remaining contenders, noted that while the field has lost a major player, the competition remains fierce. "It’s always a shame to lose a horse like Thundering On from a Classic," a spokesperson for the stable indicated. "However, it opens up the race. Johanna Walsh has been in great form since Ascot, and we believe she has found the necessary improvement to challenge Earth Shot."
Broader Implications for the Fillies’ Classic Division
The withdrawal of Thundering On leaves a void in the middle-distance filly rankings that other contenders will look to fill. If Earth Shot wins convincingly, she will likely be targeted at the Yorkshire Oaks or the G1 Nassau Stakes at Goodwood. If Johanna Walsh manages to reverse the Ascot form, she will become the leading light for the O’Brien stable heading into the autumn.
The absence of the Frankel filly also impacts the Sire of the Year standings. Every Group 1 win counts toward the seasonal championship, and Frankel is currently in a tight battle with the likes of Dubawi and Kingman.
Conclusion: A Reshaped Classic
The 2024 Juddmonte Irish Oaks will be remembered as the year the favorite changed on the morning of the race. While the withdrawal of Thundering On is a setback for the spectacle, the remaining field is of exceptional quality. The clash between Earth Shot’s Ascot-winning momentum and Johanna Walsh’s pedigree-backed potential provides a compelling narrative for one of the world’s great races.
As the fillies head to the start at The Curragh, the focus remains on the resilience and talent of the three-year-old crop. Despite the loss of a key protagonist, the quest for Classic glory remains as intense as ever, ensuring that the winner of the Irish Oaks will be a worthy addition to the roll of honor at the home of Irish racing.
