What the pattern suggests
Unlike the 7 furlong races there doesn't appear to be much of a draw bias here, as there is an extra furlong at the start before the bend which gives the horses time to sort themselves out.
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 2020–2026.
Stall-numbering note: From 30 March 2011, stall numbering on right-handed courses changed so that stall 1 is always on the inside. Earlier Sandown results in the chart have been converted to the modern numbering convention.

How to use the bias
- Pace: identify where the early leaders are drawn and which runners can secure a position before the bend.
- Tactical position: a middle stall may provide flexibility without forcing a horse immediately inside or wide.
- Field size: the practical effect of the draw usually increases as the field becomes more crowded.
- Recent evidence: rail movements, watering and weather can alter the effective bias.
Conclusion
The Sandown one-mile is different to the 7 furlong races as there doesn't appear to be much of a draw bias here, as there is an extra furlong at the start before the bend which gives the horses time to sort themselves out.
