Track Bias

Draw advantage, going preferences and favourite performance by course.

Frequently asked questions

What is track bias?

Track bias is a course's tendency to favour certain runners regardless of ability — for example a particular draw, running style or section of the track performing better under given conditions.

What is draw bias?

Draw bias is when a horse's stall (starting) position affects its chance — common in sprints, where low or high draws can hold a measurable edge at some courses.

How is draw bias measured here?

We analyse historical results by stall position, distance and going at each course to show which draws have outperformed, and by how much.

Does the AI account for track bias?

Yes — one scoring variant weights draw position directly, and each course profile surfaces its bias so you can factor it in. See the methodology.
