Nakayama Racecourse 1800m — Empirical Class Par Times & GLD Speed Figure Benchmarks
Runners climb the 2.2m homestretch hill twice (at the start and finish), making stamina and forward tactical position essential. (Inside Draw (1–4): 10.2% SR | Outside Draw (9+): 7.3% SR • Favored Running Style: Power Stalkers & Sustained Front-Runners)

Distance-by-Distance Barrier Draw & Pace Bias Matrix (Nakayama 1800m)
| Barrier / Gate Group | Empirical Indicator (% SR) | Favored Running Style | Empirical Course & Pace Notes |
|---|---|---|---|
| Inside Draws (Gates 1–4) | 10.2% SR | Power Stalkers & Sustained Front-Runners | Runners climb the 2.2m homestretch hill twice (at the start and finish), making stamina and forward tactical position essential. |
| Middle Draws (Gates 5–8) | 9.1% SR | Power Stalkers & Sustained Front-Runners | Rails A/B/C • 310m Short Stretch + 2.2m Steep Wall • Strong Inside/Early Speed Bias |
| Outside Draws (Gates 9+) | 7.3% SR | Power Stalkers & Sustained Front-Runners | 310.0m (Turf) / 308.0m (Dirt) • 5.3m total undulation with JRA’s steepest 2.2m final uphill wall (2.24% gradient) |
Frequently Asked Questions
What is the empirical Class Par and GLD Speed Figure benchmark at Nakayama Racecourse 1800m?
Nakayama Racecourse (JRA) benchmarks are calibrated directly from GLD Racing's empirical Class Par dataset (865,435 historical starts). At 1800m, standard velocities (m/s) and par finish times are normalized across the JRA class ladder alongside daily track variant and surface moisture adjustments.
What is the barrier draw and running style bias at Nakayama Racecourse 1800m?
Nakayama Racecourse features a 310.0m (Turf) / 308.0m (Dirt) homestretch (Right-Handed (Clockwise)). At 1800m, inside draws (Gates 1-4) record a 10.2% SR compared to 7.3% SR for outside draws (Gates 9+), favoring Power Stalkers & Sustained Front-Runners. Runners climb the 2.2m homestretch hill twice (at the start and finish), making stamina and forward tactical position essential.
How do surface going, rail shifts, or sand moisture affect Nakayama Racecourse speed figures?
Rails A/B/C • 310m Short Stretch + 2.2m Steep Wall • Strong Inside/Early Speed Bias. GLD Speed Figures automatically separate true horse velocity from surface speed variants so you can compare Nakayama Racecourse past performances directly against other JRA venues.
