What the pattern suggests
It is generally thought that in large fields high numbers hold an avantage over a mile at Windsor, however the advantage only appears to be slight, and this looks like another racecourse with very little real draw bias.
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.

How to use the bias
- Pace: consider where the likely early leaders are drawn and which runners can obtain a favourable position.
- Going: assess whether one side of the course is riding faster on the day.
- Field size: draw effects can become more important when runners are spread across a larger field.
- Recent evidence: rail movements, watering and weather can change the effective bias.
Conclusion
It is generally thought that in large fields high numbers hold an avantage over a mile at Windsor, however the advantage only appears to be slight, and this looks like another racecourse with very little real draw bias.
