Speed Figures Explained

Finishing positions are the most over-trusted numbers in racing. A horse wins, the form book records a 1, and everyone moves on. But a win in a slowly-run Catterick seller and a win in a Newbury handicap on heavy ground are not the same achievement, and the placings cannot tell them apart. Andrew Beyer built his whole method on that gap. The most reliable way to compare two horses, he argued in Picking Winners, is not by where they finished but by how fast they ran, adjusted for the going that day and the track they ran on. A mile handicap won in 1:37 on fast ground is a different race from a mile handicap won in 1:37 on soft. Same time on the clock, same winning margin, two completely different performances. A speed figure is the attempt to put both on one scale.

Any term on this page that’s new to you is defined in the racing glossary.

What a speed figure actually is

A speed figure is a single number for how fast a horse ran, adjusted for the going and the peculiarities of the track. Strip out the soft ground, strip out the stiff uphill finish, strip out the afternoon the clock ran slow, and what is left is a figure you can lay alongside any other. Two horses with the same figure have, in theory, shown the same level of ability, no matter that one did it on a wet Tuesday at Wolverhampton and the other on Champions Day at Ascot.

That is the promise, and on its day it is a powerful one. The figure does the one job the bare result cannot: it lets you compare performances that were never run against each other, in conditions that were never the same. Get the adjustment right and you are reading a horse’s merit rather than its circumstances.

The UK speed figure landscape

Three figures matter in British racing, and they are not all measuring the same thing.

Topspeed (TS) sits on the standard Racing Post racecard next to the Official Rating and the RPR. It is the purest time reading of the three: built from the overall time, then adjusted for the going. It is at its most reliable on fast ground at tracks with consistent, well-kept timing. On soft ground, or at a track where the clock is patchy, treat it with more caution.

RPR, the Racing Post Rating, is a different animal. It is a merit assessment that weighs the margin of victory, the class of the race and the weight carried, so it leans less heavily on the raw clock. That makes it more robust on going where times mean little, because it has other information to fall back on. Where Topspeed asks only how fast, the RPR asks how good.

Timeform is the original and still the most serious. Phil Bull built it from 1948, fusing his time-driven method with Dick Whitford’s form-driven one, and the discipline has never really been bettered. One distinction matters on this page: the familiar Timeform rating — an open-ended figure in pounds, topping out at Frankel’s 147 on the Flat and Arkle’s 212 over fences — is a form assessment, not a speed figure — Timeform’s true speed figure is the timefigure, the calculated time value of a single performance. The handy thing to carry in your head is the scale: the gap between a 120 and a 130 horse is about ten pounds of ability, which is roughly five lengths at a mile. Pounds and lengths are not a fixed exchange rate, though — the further the trip, the more lengths a pound buys. Reckon on more than three pounds to a length over five furlongs, about two pounds to a length at a mile, and only around a pound a length out at two miles. So that same ten-pound gap is nearer three lengths in a sprint but stretches past nine lengths in a staying race. Once you know that, a Timeform figure stops being an abstract number and becomes a distance you can actually picture.

One warning sits under all three, and it is specifically British. Unlike American dirt, with its narrow and predictable range, our going swings from firm to heavy and our tracks are all different shapes and gradients. The hard part of a British speed figure is the going adjustment, and the figure is only ever as good as that adjustment. Keep that in mind before you trust one to the pound.

Reading them properly

The figures earn their keep in two main ways.

Tracking one horse over time

This is where speed figures are at their sharpest. A horse that posts Topspeed figures of 88, 82 and 91 across three runs is on an improving curve, even if the finishing positions over those same three runs read first, third and second. The placings depend on what else turned up and how each race was run. The figures cut through all of that and show you the horse is getting better. That is information the result actively hides, and it is the most useful thing a figure will ever tell you.

Comparing different horses

Line a field up by their best recent figures and you have a merit order that ignores reputation, market and last-time-out placing. It is rougher than tracking one horse, because every figure carries its own going adjustment and those adjustments are approximate, but as a sanity check against the betting it is invaluable. When the favourite’s figures do not back up its price, you have found something worth a second look.

What speed figures miss in British racing

A figure is a powerful tool and a poor master, and on British racing in particular it has real blind spots worth naming.

The going adjustment is guesswork at the edges

On a flat American dirt oval the range is narrow and the daily track variant is a settled method, so the maths is cleaner. Here, turning a heavy-ground Plumpton time into a figure you can set beside a fast-ground Goodwood time is necessarily more approximate. The further the going sits from standard, the softer the figure underneath it.

Sectionals are newer than the figures

Since July 2024 every British course has pooled its sectionals into one industry database — 59 courses, records back to August 2023 — so coverage is no longer the gap; the analysed products built on them, pars and stride reads, are what remain patchy. A figure built on the overall time alone is still wide open to pace distortion. A fast time run as a steady gallop into a three-furlong sprint is not the same as a fast time run end to end, but without the splits the figure cannot tell the two apart. This is exactly where sectional times pick up where the speed figure runs out.

Formdial’s free Pace Analyser does the mechanical half of this: it scores a field’s recent run styles and maps the likely shape.

Over jumps, the clock does not measure jumping

A horse that pings its fences runs a faster effective time than one that scrambles and clouts its way round, yet the two can stop the clock together. Elapsed time says nothing about how the time was earned. Over hurdles and fences, a figure is only ever part of the story.

Using them to find a bet

Held with their limits in mind, speed figures point you at three kinds of value that are easy to walk past.

Hidden improvement

A horse whose figures keep climbing while it keeps getting beaten is telling you something the placings are not. The improvement is real even if the win has not come yet, and the day it finally gets the right setup, it is overpriced.

Hidden class. A horse that posted a standout figure on fast ground and has since run ordinary figures on soft is very probably a fast-ground specialist whose mark has not been pushed up much by those quiet runs on unsuitable ground. Catch it back on a sound surface and it can be sitting well ahead of its handicap mark.

The pace-flattered career-best. Be suspicious of a top figure set in a slowly-run race that turned into a dash for home. That number may simply not be reproducible once the race is run on its merits from the front. Read the shape behind the figure before you trust it, which is where pace bias and sectionals come back into it.

How speed figures fit with the rest

So treat the figure as a starting point, never a conclusion. It tells you, better than the form book ever could, what a horse has already done. It cannot tell you what it will do next, in today’s going, over today’s trip, against today’s field. That last step is yours, and it is where the bet is actually won. The number gets you to the right shortlist. Judgement gets you to the right price.
