The form guide is the most important document in horse racing. It contains the history of every horse's performances — where it ran, what the conditions were, how it finished, and what that run was worth in measurable terms. For new punters, it can look impenetrable. For experienced form students, it is a structured conversation between the evidence and the price. This guide explains how to read it from the beginning.
The Form Figures
The form string — the sequence of numbers and letters next to each horse's name — is the starting point for any form assessment. Each character represents a run, with the most recent on the right. A form string of 3-1-2 means the horse finished third in its last-but-two run, won its penultimate run, and finished second most recently. Reading from left to right is reading backwards through history.
The characters used are: 1 through 9 for finishing positions, 0 for finishing tenth or lower, F for fell, U for unseated rider, P for pulled up, R for refused, and B for brought down. A form string with multiple dashes (---) indicates a gap in the record — usually a period of absence. A form string beginning with letters from the previous season is sometimes separated by a slash to mark the season break.
The numbers alone do not tell the full story. A third-place finish in a Group 1 race is a very different form line to a third-place finish in a Class 6 seller. Context — the class, the going, the distance, and the opposition — is what gives the numbers meaning.
Going
Going describes the ground conditions on the day of the race: firm, good to firm, good, good to soft, soft, heavy — and variations thereof for jumps racing. Horses have preferences. Some produce their best form on fast ground and underperform significantly when conditions soften. Others are sluggish on firm going and come alive on soft. Identifying a horse's going preference and checking it against the declared conditions for today's race is one of the first and most important steps in any form assessment.
Going is expressed in historical form records as a letter code: F (firm), GF (good to firm), G (good), GS (good to soft), S (soft), H (heavy). When reading a horse's historical form, noting the going for each run alongside the result reveals the preference pattern.
Class
British racing divides into classes from 1 (the highest) to 7 (the lowest) for Flat racing, and from Grade/Group 1 down through Grades 2 and 3, Listed, Class 1 through 5 for jumps. A horse moving up in class — from Class 4 to Class 3 — faces stronger opposition. A horse dropping in class faces weaker. Both moves carry analytical significance, and neither is automatically positive or negative without considering why the move has been made.
The Key Numbers
The Official Rating (OR) is the handicapper's assessment of the horse's ability, expressed as a number. The Racing Post Rating (RPR) is an independent assessment of the horse's actual performance level, calculated from the form. When the RPR significantly exceeds the OR, the horse may be running off a mark that does not fully reflect its ability — a potential edge. The Topspeed figure (TS) measures the horse's time performance in its most recent run, useful as a secondary check on the RPR.
Connections
The trainer and jockey listed for each horse are the final layer of the form picture. Trainer strike rates — the percentage of runners that have won — indicate whether the yard is in form. Jockey bookings signal yard confidence when a top rider is brought in for a horse that could have been ridden by a more junior partner. Both variables add behavioural information that the horse's bare form figures cannot provide.
Reading the form guide is a skill that develops with practice. The basics — form figures, going, class, ratings, connections — provide the framework. Every additional layer of analysis adds precision. Horse Racing Oracle AI processes all of these variables simultaneously for every horse in every race, producing the daily NAP selection from the most complete evidence base available.
