What the pattern suggests
Ascot's round mile is very rarely used, and when it is the field sizes are quite small, which suggests there is no strong draw bias on this course. However, there is a view that being drawn low can be a disadvantage, as it risks horses being boxed in on the rail even in small fields.
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: From 30 March 2011, stall numbering on right-handed courses changed so that stall 1 is always on the inside. Earlier Ascot results in the chart have been converted to the modern numbering convention.

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
They very rarely use the round mile at Ascot, and when they do the field sizes are quite small and therefore it would suggest that their is no draw bias on the Ascot round mile. However their is a view that being drawn low is a disadvantage as it results in horses being boxed in on the rail even in small fields.
