比叡ステークス2025: Key Insights and Top Picks

  • The Kyoto Turf 2400m is a demanding course requiring both stamina to conquer the “Yodo Hill” and a sustained late kick.
  • Our top pick is Aqua Vernal, boasting a stellar track record on this very course. Excellent training further solidifies its position as a reliable contender.
  • Challenging Aqua Vernal is Danon Cima, a 3-year-old with significant growth potential and a favorable weight advantage, hinting at possibilities beyond the raw data.
  • Remige, the AI’s highest-rated horse, presents a strong case due to its adaptability to tougher track conditions and exceptional training performance.
  • The outcome of the race hinges on re-evaluating the pecking order of horses from the “Koto Stakes” and accurately assessing the distance suitability of the dark horses.

比叡ステークス2025: Executive Summary & Race Overview – Kyoto 2400m Turf Challenge

The Hiei Stakes, held over 2400m on the Kyoto Racecourse turf, is a pivotal “3-win class” (준 오픈) event where horses vie for promotion to open class. This challenging course demands not only sheer stamina but also the refined maneuverability to navigate Kyoto’s iconic “Yodo Hill,” culminating in a sustained late kick from the downhill run into the straight. This analysis leverages AI prediction data, training times, stable comments, and past race results to provide a comprehensive race preview and evaluation of key contenders. This year, the focus intensifies on the dynamic interplay between “proven course specialists” and the “potential of emerging forces,” primarily examining the top performers from the “Koto Stakes” alongside promising 3-year-olds and rapidly improving horses.

Course Dynamics: Mastering the Kyoto Turf 2400m

The Kyoto Turf 2400m outer course features a unique topography, including an uphill climb of approximately 4 meters in elevation from the middle of the backstretch to the 3rd corner, followed by a descent towards the 4th corner. This undulating terrain is unforgiving, weeding out horses with stamina concerns or difficulty settling. Success here demands the ability to accelerate effectively on the downhill slope and maintain that momentum through the lengthy final stretch. Consequently, significant weight is given to horses with a proven record on this course or a pedigree suggesting strong long-distance suitability.

Integrated Contender Analysis: Fusing Data with Context

A careful examination of AI prediction indicators and expert handicapper selections reveals several prominent contenders poised for victory.

The Unwavering Anchor: Aqua Vernal (Gate 1, Stall 2)

  • Performance Profile & Course Suitability: Aqua Vernal demonstrated remarkable performance in the previous “Koto Stakes” (November 2, 2025, Kyoto Turf 2400m), finishing a close 2nd by only a nose. Jockey Y. Kitamura commented, “The horse ran smoothly, settled well, and maintained a good rhythm. It took the initiative at the crucial point.” This underscores its exceptional adaptability to Kyoto’s long-distance layout and its excellent mental state.
  • Training & Condition Trajectory: Despite a tight two-week turnaround from its last race, training data indicates an upward trajectory in condition. Its final workout on November 19 at Ritto CW course recorded 83.9 seconds over 6 furlongs, with a blazing 11.8 seconds for the final furlong, effortlessly outpacing its workmate. Described as “light-footed and agile,” combined with a 10kg weight gain since the previous race, Aqua Vernal appears to have matured and is reaching peak form.
  • Pedigree & Race Flow: Sired by Epiphaneia out of a Deep Impact mare, Aqua Vernal boasts a classic pedigree for turf middle-to-long distances. Trainer Yotsui expressed confidence, stating, “It won consecutive races over 2400m, so we’re still very optimistic.” Drawing the inner gate (2) is highly advantageous, allowing for a ground-saving trip and a smooth breakout in the crucial stages, making a repeat strong performance highly probable.

Rising Star Aiming for Generational Shift: Danon Cima (Gate 3, Stall 5)

  • Potential & Weight Advantage: As a 3-year-old colt, Danon Cima benefits from a significant 56kg weight advantage over older males (carrying 58kg). Its overwhelming victory in the “Hyogo Tokubetsu” (Hanshin Turf 2400m) suggests it is ready to challenge higher classes immediately. Jockey A. Nishimura noted, “Its ability was on another level. It has grown immensely since I last rode it.”
  • Training Analysis & Growth: Despite a longer break between races, Danon Cima has been meticulously trained. Its final workout on November 19 at Ritto坂路 saw it clock 11.9 seconds for the final furlong effortlessly. Assistant Trainer Fukunaga commented, “It has improved with every workout. Its condition is optimized for peak performance.”
  • AI vs. Human Evaluation Discrepancy: While AI rates Danon Cima as “△ (runner-up contender),” human handicappers have designated it as “◎ (top pick).” This divergence likely stems from AI’s conservative assessment of 3-year-old growth, whereas human experts place high value on its impressive previous victory. This suggests Danon Cima possesses explosive potential beyond mere data points.

AI’s Top Pick: Remige (Gate 4, Stall 7)

  • Data-Driven Suitability: Remige receives the highest “◎” rating from the AI, primarily due to its “consistent early speed” and “aptitude for tough track conditions.” Its 3rd place finish in the “Niigata Himba Stakes” (Turf 2200m) confirms its capability at an open-class level.
  • Stable Strategy & Track Adaptability: Trainer T. Inoue remarked, “For a one-lap race, extending the distance could be even better. Moreover, the deteriorating Kyoto turf will be a plus.” As the meeting progresses and the Kyoto turf becomes heavier, its power and sustained effort, characteristic of Kizuna progeny, could be fully unleashed.
  • Training Excellence: On November 19, Remige recorded 53.8s – 12.3s on the Ritto坂路 with a strong finish, earning the commendation “movement stands out.” A week prior, it clocked 79.4s on the CW, indicating top-tier physical condition. A scenario where it sets the pace and holds on in the stretch is certainly plausible.

Leading Stable Force: Gamble Room (Gate 8, Stall 15)

  • Re-evaluation of “Koto Stakes”: Gamble Room finished a commendable 3rd in the “Koto Stakes,” just behind Aqua Vernal. Jockey R. Wada reflected, “The response was good, and it would have been better if we could have flowed more smoothly from the critical point.” This suggests an untapped potential due to a less-than-ideal race development.
  • Training & Condition Maintenance: Despite a two-week interval, its November 19 CW workout showed “relaxed and fluid movement” while unasked. Its physique is described as “no stiffness, with a plump outline,” confirming no lingering fatigue from the previous race and maintaining a high level of condition.

Detailed Analysis & Hierarchy of “Koto Stakes” Group

The key to deciphering this race lies in evaluating the horses that competed in the previous “Koto Stakes.”

Rematch Dynamics Among Top Finishers

The Hiei Stakes features a rematch among the top finishers from the Koto Stakes: Aqua Vernal (2nd), Gamble Room (3rd), Aster Bujie (4th), and Taisei Ferrique (5th). Based on current data, the hierarchy among these four could shift due to the following factors:

スポンサーリンク

  • Aqua Vernal: Its versatility, less dependent on race development, and near-identical time with the winner in the previous race make it the frontrunner within this group.
  • Gamble Room: The far outside gate (8枠15番) poses a challenge. There’s a risk of expending too much energy to secure a good position, so a smooth run will be crucial.
  • Aster Bujie: In the previous race, it made up ground from the rear, hugging the rail. Jockey Y. Furukawa noted, “For a moment in the straight, it felt like we could win.” This horse possesses significant explosive power if the race unfolds favorably.
  • Taisei Ferrique: While an upset over the top three would require substantial improvement, the training comment “body appears lean” raises concerns about its current physical condition.

Considering these points, the estimated hierarchy within the Koto Stakes group is Aqua Vernal> Gamble Room ≥ Aster Bujie> Taisei Ferrique.

Dark Horses and Potential Longshots

Beyond the likely favorites, several horses possess significant potential and should not be overlooked.

スポンサーリンク

Distance Extension is Key: Baronessa (Gate 1, Stall 1)

  • Although by Lord Kanaloa (known for speed), her dam’s sire is Orfevre, providing a strong stamina foundation. As the stable commented, “the distance extension should be a plus,” this significant step up to 2400m could be the catalyst to unleash her late speed. Drawing the innermost gate could allow for a ground-saving trip, hinting at a potential upset.

Showing Signs of Recovery: Red Terios (Gate 5, Stall 10)

  • Returning from a long layoff, Red Terios’s past victory over 2500m at Nakayama is a significant asset in a stamina-testing race. Despite “average times but good movement” in training, the discrepancy where AI rates it as a “longshot” but track reporters give it high marks indicates a “data conflict” — a classic sign of an intriguing value bet.

Riding the Momentum: Win Tremendes (Gate 2, Stall 4)

  • While stepping up in class, its “astonishing late kick” in the previous race and the stable’s confidence that “weaknesses are improving” are highly attractive. The continued partnership with legendary jockey Y. Take adds further reassurance. If the race pace suits, Win Tremendes possesses the potential to break through the class barrier.

Race Development Simulation & Pace Prediction

Predicted Pace: Slow to Moderate

With no clear runaway leader, horses like Win Routine and the forward-running Remige are expected to set the pace.

  1. Early Stages: Inner gate runners such as Baronessa and Aqua Vernal will secure good positions along the rail. The field is expected to settle quickly.
  2. Backstretch: The pace will likely ease on Kyoto’s uphill climb, causing horses struggling to settle to drop back. Danon Cima will ideally conserve energy in the mid-pack.
  3. 3rd to 4th Corner: The pace will gradually accelerate on the “Yodo Hill” descent. Kyoto specialists like Aqua Vernal and Gamble Room will naturally pick up speed, positioning themselves to challenge the leaders.
  4. Homestretch: Aqua Vernal will aim to overtake the front-running Remige. Danon Cima will launch a powerful challenge from the outside, while Aster Bujie and Gamble Room will charge through the field. We anticipate a thrilling battle demanding a combination of stamina and burst speed.
