Kempton draw bias

What each part of the draw has really been worth at Kempton, in lengths against the field average, measured from every Flat race here since 2014. Positive figures finish closer to the winner than the field does; negative ones give lengths away at the stalls.

The strongest measured effect: High draws have cost 2.59L per run over 16f to 19f, across 543 runs.

The whole picture, every trip

Every stalled run at Kempton together. The trip tables below tell the finer story: a bias at 5f can vanish, or flip, at a mile.

Run styles from each part of the draw

Win rates for horses ridden in each early-position style from each part of the draw at Kempton. A front runner drawn low and one drawn wide are not the same bet, and no course average says so.

How to read these figures

The draw is read as a rank among the stalls actually occupied, cut into five bands from Low to High, so an 8-runner field and a 20-runner field compare honestly. Fallers and horses pulled up carry no beaten distance and are left out of their race’s average, races with fewer than 5 stalled runners are skipped, and a figure is only published where at least 100 runs sit behind it. The full method is on the draw bias index.
