Race Overview

  • Date: Saturday, December 20, 2025
  • Racecourse: Hanshin, Race 11
  • Conditions: 1200m Turf (Right-handed, A-Course)
  • Type: Handicap, 3-year-olds and up, Open Class
  • Forecast: Clear / Good to Firm

The Hanshin 1200m course has a short run to the first corner, often leading to a fierce battle for the lead. Horses drawn inside with early speed tend to have an advantage, especially on a firm track. However, a fast pace can set the race up for closers to make a late surge.

Top Contenders: Workout & Pedigree

SATONO CARNAVAL

Workout Grade: A

Odds4.7

Weight56.0kg

PedigreeKitasan Black x Numerous

Workout Analysis: Executed his final workout on Dec 17th on the Miho woodchip course, clocking an impressive 51.9-36.6-11.2 while under wraps. Despite a layoff, his preparation has been thorough, including a strong gallop last week. The stable commented, “His spirit is up. We’re sending him out with confidence.” He appears to be in perfect condition.

Aptitude: While his sire, Kitasan Black, was a stayer, his progeny often possess excellent speed. The American bloodline from damsire Numerous provides a foundation for success in sprint contests.

ASAKARA KING

Workout Grade: B+

Odds6.1

PedigreeKizuna x King Halo

Workout Analysis: Clocked 52.6-38.5-25.1-12.4 on the Miho hill course on Dec 17th. Reports note his “mind and movement are now in sync, and he’s moving with ease.” This marks a significant improvement. His preparation for a return to turf after a dirt race has been exceptionally smooth.

Aptitude: The Kizuna x King Halo cross is known for producing horses with a potent, sustained finishing kick. The demanding pace of the Hanshin 1200m could play perfectly to his strengths.

CARLO VELOCE

Workout Grade: B

Odds5.9

Weight57.0kg

PedigreeSilver State x Rock of Gibraltar

Workout Analysis: Posted 52.4-37.1-24.4-12.5 on the Ritto hill course under a strong ride.

Aptitude: Typical of a Silver State offspring, he excels at maintaining high speed. His damsire, Rock of Gibraltar (from the Danzig line), further enhances his suitability for the 1200m sprint.

Special Mention: Clocked a blistering 67.5-51.7-38.0-11.1 on the Ritto Polytrack. Described as “showing remarkable finishing speed” after an intense workout. His training signals a serious attempt at a major form reversal.

MIRTO CRAIMO

Forecast Odds: 58.0 (14th fav)

Grade A Workout: Recorded the day’s fastest time on the Ritto hill course with 51.4-37.4-24.5-12.5. Evaluated as “powerful, tenacious, and well-finished.” Despite recent poor results, a performance like this makes him a potential upset.
