Track & conditions
Track Bias
Track bias is a consistent advantage held by runners in a particular position or racing pattern on a given day — the inside lane holding up while wide runners struggle, or on-pace runners dominating while closers cannot make ground. Bias is created by rail position, weather, surface wear and pace. Recognising it matters twice: it explains results on the day, and it prevents misreading a bias-assisted win as improved form next start.
In use
Every winner on the card came from the first three at the turn — a strong on-pace bias.
On FormRace
FormRace detects same-day bias at each venue and carries a track-bias feature block into its model.
