What the pattern suggests
This is a surprising result considering how extreme the draw bias is over 5 furlongs at Chester — there doesn't actually appear to be any bias at all over 6 furlongs, although in bigger fields low may be slightly favoured.
How to read the chart
Each mark represents a winning stall number plotted against the total number of runners. This reveals whether winners repeatedly cluster towards the low, middle or high side.
The source chart covers horses aged three and older in handicaps from 2024–2025.
Stall-numbering note: Stalls at Chester are always positioned on the inside of the track.

How to use the bias
- Pace: identify where the likely early leaders are drawn and which runners can secure a good position.
- Going: consider whether the inside or outside is riding faster on the day.
- Field size: draw effects are often more meaningful when runners are crowded into larger fields.
- Recent evidence: rail movements, watering and weather can alter the effective bias.
Conclusion
A very surprising result considering how extreme the draw bias is over 5 furlongs at Chester, there doesn't actually appear to be any bias at all over 6 furlongs. Although in bigger fields low is maybe slightly favoured.
