Key Predictive Factors
Nakayama 1200m Course & Pedigree
- →Turf Start & Early Pace: Rapid acceleration from a turf start, especially from wide draws, makes absolute speed a critical factor.
- →Uphill Finish: The steep incline before the finish line demands both speed and raw power to maintain momentum.
- →Pedigree Advantage: North American dirt bloodlines (Mr. Prospector, Storm Cat) are heavily favored. Look for offspring of Henny Hughes, Drefong, Volatile, and Shancelot.
Workout Evaluation Criteria
- →Time & Speed: Fast times are key. Target 50-51s for 4F on the uphill track or low 80s for 6F on the CW course.
- →Lap Splits: Maintaining or increasing speed in the final furlong is a strong positive indicator.
- →Stablemate Comparison: Outperforming higher-rated or in-form stablemates in drills is a significant sign of readiness.
