2025 Saudi Arabia Royal Cup Preview: Don’t Miss the Birth of a Future Star!

On October 11, 2025, Tokyo Racecourse will host a pivotal event for two-year-old thoroughbreds: the Saudi Arabia Royal Cup (G3) over 1600 meters on the turf course 1. This isn’t just any two-year-old stakes race; it’s renowned as a “stepping stone” where past winners frequently go on to achieve brilliant success at the G1 level, captivating horse racing fans nationwide 2.

In a race featuring young, lightly-raced horses, the most crucial indicator for predicting victory is the “workout” (or oikiri). The final adjustments leading up to the race reveal how each horse moves and the confidence expressed by their connections. This information speaks volumes, serving as an invaluable tool for evaluating the potential of these yet-to-be-fully-unveiled talents.

This year’s Saudi Arabia Royal Cup presents an intriguing dynamic. Historically, horses with just one career start have boasted an impressive record of [8-8-3-14] (wins-seconds-thirds-unplaced), achieving a remarkable 57.6% place rate 2. This trend suggests the race is a perfect stage for unknown talents to unleash their latent potential. However, this year’s entry list includes Ask Edinburgh, the sole horse with two career wins, making it a key focal point whether its superior maturity and experience can defy this established trend 1.

This article provides a thorough analysis and evaluation of the leading contenders’ workouts, based on information gathered over the past month from various Japanese horse racing media outlets. We delve deep into each horse’s condition from an expert perspective, getting to the core of the race.

S-Rated Contenders: Ask Edinburgh’s Experience vs. Zoroastro’s Raw Talent

Remarkably, the highest “S” rating in this year’s workout evaluations went to two contrasting horses: Ask Edinburgh, who leads in experience, and Zoroastro, who harbors immeasurable potential. Let’s thoroughly compare their preparations.

Ask Edinburgh – The Sole Two-Time Winner, Leading the Generation in Maturity

Ask Edinburgh is the only horse in the entries to have already secured two victories. Its strength, however, extends beyond just experience. In its workouts, the colt has displayed a level of maturity far beyond that typically seen in a two-year-old.

One-Week-Out Workout Analysis

The one-week-out workout on the Woodchip (CW) course at Ritto Training Center was nothing short of breathtaking. Facing older, more seasoned horses, Ask Edinburgh powered through 6 furlongs in 82.6 seconds, with a blistering final furlong of 11.7 seconds, outpacing its sparring partner by a remarkable 0.5 seconds 3. This performance isn’t just about fast times; it demonstrates a fierce competitive spirit in a race-like scenario and a superior physical ability that belies its age. Trainer Yuichi Fukunaga enthusiastically endorsed its readiness, stating, “The clock was ideal, and its movement was excellent. It has speed and is the type to perform well from its debut” 4.

Unwavering Confidence from the Connections

The stable’s comments reveal unwavering confidence. Reflecting on its previous race, they noted, “Even on a poor track, it moved powerfully,” highlighting its adaptability regardless of track conditions 5. While still showing youthful tendencies in temperament, it is praised for being “highly manageable and possessing ability,” indicating no concerns about its race-day conduct 5. Ask Edinburgh’s high level of maturity and professionalism are its greatest assets in directly challenging the historical tendency of the race favoring horses with only one start. The connections are clearly strategizing to maximize its experience and adaptability to neutralize the latent potential of its rivals.

Overall Assessment (S)

With an undefeated record from a maiden race and the Cosmos Sho, coupled with an impeccable workout performance 3, Ask Edinburgh is in perfect physical and mental condition. A third consecutive win, securing a graded stakes title, appears highly probable.

Zoroastro – A G1 Caliber Colt with Untapped Potential

If Ask Edinburgh symbolizes “maturity,” Zoroastro is a pure embodiment of “potential.” With only one career start, its workouts hint at a G1-caliber talent.

Stunning Final Workout (S Rating)

The final workout on the W course at Miho Training Center garnered the highest ‘S’ rating from multiple media outlets 6. Its movement was universally praised as “magnificent strides” and “overflowing with dynamism.” It completed 5 furlongs in 68.2 seconds, with a final furlong in 11.6 seconds, effortlessly matching a higher-ranked stablemate 6. Beyond the clock, the sheer quality of its running was exceptional.

Connections Speak of Extraordinary Mental Fortitude

The most crucial factor in evaluating Zoroastro is its rare mental fortitude. Relations have effusively praised its composure, unusual for a two-year-old, with comments like “It’s like an adult horse,” “Its mentality and physique didn’t seem like a two-year-old’s,” and “It was calm both before and after the workout” 8. Trainer Keisuke Miyata also lauded its manageability, stating, “Even with its large strides, it didn’t push its jaw out, and it took the bit well,” and “It accelerated smoothly” 6. In two-year-old races, many horses fail to perform due to youthful temperament; this mental maturity is an immeasurable advantage. It is this calm mind perfectly controlling its exceptional physical ability that allows for such an S-rated performance. It’s no wonder the trainer described it as a “horse with so much appeal, its depth is unknown” 9.

Overall Assessment (S)

Zoroastro’s powerful closing speed, stemming from a muscular, American-bred physique 10, is underpinned by remarkable mental maturity. Its workout performance clearly demonstrates the immense potential it possesses. With the palpable aura of a future star, its preparation is unequivocally flawless.

A+ Rated: Dark Horses Aiming for the Crown – Perfectly Prepared for an Upset

Two A+ rated contenders have been prepared in a condition comparable, if not equal, to the S-rated duo. These dark horses hold significant potential for an upset, and we analyze their status.

Chuwa Carnegie – Jockey Praises Dynamic Movement

Final Workout Review

In its final workout on the Ritto uphill track, the times—4 furlongs in 55.2 seconds, with a final furlong of 12.3 seconds—were not particularly eye-catching 11. However, the quality of its movement was paramount. Jockey Yuichi Kitamura, who was aboard, testified to its improved condition, stating, “It’s much better than when I rode it three weeks ago,” and “I felt its body was fully prepared.” He enthusiastically described its movement as “dynamic, as if it could explode at any moment” 12. Such high praise from a jockey, who intimately knows the feel of the horse, carries more weight than mere numbers.

Debut Performance and Physique

The source of its powerful movement lies in its impressive physique, weighing over 500 kg 2. In its debut race, leading wire-to-wire, it recorded astonishing sectional times: a final 3 furlongs in 33.2 seconds, with the last 2 furlongs in 10.9-10.9 seconds, clearly demonstrating its immense speed 2. If the power shown in training combines with the speed proven in races, Chuwa Carnegie will undoubtedly pose a serious threat to the S-rated horses.

Overall Assessment (A+)

With its jockey absolutely smitten by its excellent condition and its already proven high ability, Chuwa Carnegie is in peak form. There’s a strong possibility it can overcome the new challenges of the Tokyo course and transportation, thanks to its current robust state. It approaches this graded stakes race perfectly prepared.

Ecolo Alba – Stable Adores Extraordinary Closing Speed

Workout Content and Times

What makes this horse’s evaluation both challenging and exciting is the stable’s adjustment strategy. In its one-week-out workout, despite the heavy track conditions making fast times difficult, Ecolo Alba showcased superb acceleration with a final furlong in 11.1 seconds on the Miho wood course. Trainer Yasuhito Tamura showered it with praise, saying, “A truly excellent run. Frankly, I have no complaints” 13. In contrast, its final workout was a more reserved effort, completing 4 furlongs in 55.2 seconds with a final furlong in 12.3 seconds 11.

Stable Comments Analysis

This seemingly conservative final workout has a clear purpose. Trainer Tamura remarked, “If we pushed it, the times would be incredible, so we kept it to this today,” indicating that he fully understands the horse’s ability and deliberately held it back from a full-speed gallop 14. This implies a significant untapped reserve, not reflected in the workout times. The jockey also commented, “The horse has improved compared to before,” and “It’s ready to perform even after a break,” confirming flawless preparation 11.

Overall Assessment (A+)

Ecolo Alba’s workouts, intentionally reserved yet showcasing exceptional bursts of speed when needed, convey a stable deeply impressed by its potential and adjusting it with careful boldness. When it unveils its true power on race day, there’s a possibility of a sensational closing kick from this contender.

Other Noteworthy Contenders: Workout Analysis (B+ Rated)

Beyond the top-rated horses, several other contenders are in good form and are quietly vying for their chance.

Nishino Ace Summer (Rating: B+) The most significant highlight for this horse is its mental growth. As trainer Yuichi Shikato noted, “It has become much easier to control compared to before,” indicating that a period of pasture rest has refreshed it both mentally and physically, drastically improving its tractability 15. In its final workout, with Kosei Miura aboard, it maintained a steady rhythm and finished alongside its partner 15. While not flashy, the fact that it is now in a state to maximize its ability in a race is highly commendable.
You Pharaoh (Rating: B+) This horse boasts some of the best speed in the field. In its final workout, it clocked a blazing 4 furlongs in 51.3 seconds on the uphill track, setting a new personal best 16. Trainer Hideyuki Mori observed its excellent condition with satisfaction, stating, “Both the time and movement were good. It’s getting better with each race” 16. While a distance extension might be key, its preparation is beyond reproach.
Galilea (Rating: B) A steadily improving prospect. After its workout, trainer Hidekatsu Shimizu explicitly stated, “It has gained strength compared to when it ran in the summer,” suggesting it is currently in peak form 17. While it may not display the flashy movements of the top contenders, its consistent improvement curve makes it a horse not to be underestimated.

Workout Rating Summary and Final Thoughts

Summarizing our analysis, this year’s Saudi Arabia Royal Cup appears to be centered around two strong contenders: Ask Edinburgh, with its superior maturity, and Zoroastro, with its G1-caliber potential. However, Chuwa Carnegie, lauded by its jockey, and Ecolo Alba, harboring immense hidden potential, are also impeccably prepared, giving them ample opportunities for an upset.

The high level of this year’s race is further underscored by the fact that many strong contenders followed an ideal training regimen: applying significant load one week out and then focusing on breath control in their final workout. The ultimate outcome will likely hinge on the mental maturity typical of two-year-olds and their ability to adapt to race-day conditions.
