Draw bias is one of those things that gets mentioned constantly but is often either overstated or applied too loosely. “Low draw at Chester” has become a reflexive thing people say without necessarily knowing the specifics. So here’s what we know from the data, where draw bias is real and meaningful, and where it’s mostly noise.

What draw bias is and why it happens

When horses line up in stalls for a flat race, each horse has a numbered position. Stall 1 is on the inside rail (the left-hand side on most British courses), and the numbers go up towards the outside. On a straight course, stall 1 is usually on the far side (stands’ side) or near side depending on the track.
