How to Read BRISNET Past Performances — A Complete Beginner's Guide
Published May 29, 2026 by Horse Race Ready — Model v6.6.0
What Are BRISNET Past Performances?
BRISNET past performances (PPs) are the standard data format for thoroughbred handicapping. Every serious handicapper reads PPs — they contain the complete racing history, speed figures, running lines, trainer/jockey stats, and more for every horse in the field.
Key Fields in BRISNET PPs
- Date / Track / Distance / Surface: When and where the race happened
- Speed Figure (BRIS): Normalized time rating — higher is faster
- Running Line: Position at each call (start, 1st call, 2nd call, stretch, finish)
- Beaten Lengths: How far behind (or ahead) at each call
- Post Position: Starting gate number
- Odds: What the public thought — useful for spotting improving horses the public missed
- Equipment: Blinkers, front wraps, etc. — changes from last race are flagged
- Medication: Lasix (L), Bute (B), and first-time Lasix indicators
Reading the Running Line
The running line is the most information-dense part of the PP. "3 2½ 2¹ 1½ 1²" means the horse broke third, moved to 2½ lengths back at the first call, was 2nd by 1 length at the second call, took the lead by ½ length at the stretch call, and won by 2 lengths. This tells you the horse's running style and tactical ability.
BRISNET PPs in Horse Race Ready
Horse Race Ready is built on BRISNET data. Our parser extracts every field from BRISNET PPs and feeds it into the 10-factor scoring model — so you get the benefit of deep PP analysis without manually reading hundreds of lines of data.
