Form refers to the performances of a horse in its recent races, and in most cases form guides are available for reference.
0 – Did Not Place
1 – First Place
2 – Second Place
3 – Third Place
U – Unseated Rider
P – Rider Pulled Up
The most recent race result is furthest left, so in the following example 011123-UP means the horse had been unplaced, first, first, first, second, third, unseated rider and pulled up in its most recent runs. Runs in the last season are after the dash.
