Distance-by-Distance Barrier Draw & Pace Bias Matrix (Sonoda)
| Distance | Inside Draw (1–4) | Middle Draw (5–8) | Outside Draw (9+) | Favored Running Style | Empirical Course & Pace Notes |
|---|---|---|---|---|---|
| 1230m (View Guide →) | 12.1% SR | 8.8% SR | 5.6% SR | Inside Gate Speed (SPD) & First-Turn Leaders | Sonoda’s unique sprint distance starting in the 2nd-corner chute: inside draws grab the rail and dominate the 213m finish. |
| 1400m (View Guide →) | 11.2% SR | 9% SR | 6.4% SR | Tactical Stalkers & 3rd-Corner Uphill Movers | Sonoda’s signature distance (Hyogo Championship / Hyogo Gold Trophy): horses must be in the top 3 cresting the 3rd-corner hill. |
| 1870m (View Guide →) | 10.4% SR | 9.1% SR | 7% SR | Sustained Stamina Stalkers & Early Movers | Demanding six-turn route climbing the 1.2m backstretch slope twice; rewards stamina and agile cornering. |
Frequently Asked Questions
How are GLD Speed Figures and Class Par times calibrated at Sonoda Racecourse?
Sonoda Racecourse (NAR) benchmarks are calibrated directly from GLD Racing's empirical Class Par dataset (865,435 historical starts). At 1230m, standard velocities (m/s) and par finish times are normalized across the NAR class ladder alongside daily track variant and surface moisture adjustments.
How do track geometry and barrier draws impact races at Sonoda Racecourse?
Sonoda Racecourse features a 213.0m (Dirt) homestretch (Right-Handed Tight 1051m Oval). At 1230m, inside draws (Gates 1-4) record a 12.1% SR compared to 5.6% SR for outside draws (Gates 9+), favoring Inside Gate Speed (SPD) & First-Turn Leaders. Sonoda’s unique sprint distance starting in the 2nd-corner chute: inside draws grab the rail and dominate the 213m finish.
How do surface going, rail shifts, or sand moisture affect Sonoda Racecourse speed figures?
1051m Tight Oval • 213m Short Straight • 1.2m Backstretch Climb • Early Speed & 3rd-Corner Makuri. GLD Speed Figures automatically separate true horse velocity from surface speed variants so you can compare Sonoda Racecourse past performances directly against other NAR venues.
