JRA Central Racing (Tokyo, Kyoto, Nakayama, Hanshin): Course Geometry & Class Pars
JRA Central Racing is Japan’s premier circuit featuring world-leading prize money. Turf courses utilize blends of wild and Western grass, with movable rail positions (A, B, C) and sweeping home straights.
Class Par Benchmarks: Standardizing Performance Across Tiers
Whether a last-out maiden winner can compete against winners is determined by comparing their historical speed rating directly against historical class pars.
- Maiden to 1-Win Class: Rapid developmental trajectories where improvers gaining +5 pts produce high-yield upsets.
- 2-Win to 3-Win Class: Pace tightens dramatically into sustained pressure contests.
- Open / Graded Stakes (G3/G2/G1): Every 1kg of weight carried equates to approximately 0.2s of deceleration; GLD physics isolate true superiority.
