Frequently Asked Questions
What is the empirical Class Par and GLD Speed Figure benchmark at Happy Valley Racecourse 1650m?
Happy Valley Racecourse (HKJC) benchmarks are calibrated directly from GLD Racing's empirical Class Par dataset (865,435 historical starts). At 1650m, standard velocities (m/s) and par finish times are normalized across the HKJC class ladder alongside daily track variant and surface moisture adjustments.
What is the barrier draw and running style bias at Happy Valley Racecourse 1650m?
Happy Valley Racecourse features a 310.0m (Course A) to 338.0m (Course C+3) homestretch (Right-Handed Tight Inner-City Oval). At 1650m, inside draws (Gates 1-4) record a 11.9% SR compared to 5.1% SR for outside draws (Gates 9+), favoring Inside-to-Mid Rail Savers & Backstretch Movers. Starts in the tight grandstand chute with barely 150m to the first turn; gates 1–5 save vital ground around three tight bends.
How do surface going, rail shifts, or sand moisture affect Happy Valley Racecourse speed figures?
Rails A, B, C, C+3 • Tightest Turn Radius in HK • Extreme Inside/Speed Bias on C & C+3. GLD Speed Figures automatically separate true horse velocity from surface speed variants so you can compare Happy Valley Racecourse past performances directly against other HKJC venues.
