Module 2.4 – The System Builder – Trainers and Jockeys

Updated 15 October 2026

In this module we will look at how to use the system builder to analyse trainers, jockeys and combinations of both.

We will show you how to analyse against horses declared to run today, when having their first or second run for a new trainer and how to produce a trainer cold list.
