How are speed ratings calculated?

We start from the raw finishing time and layer contextual adjustments on top: going and surface, race distance, the pace the race was run at, course configuration, draw position, class and field strength, and weight carried. Those adjustments normalise the run so it sits fairly against performances at any other track.

What is a good speed rating?

There is no universal 'good' number, because a rating is only meaningful relative to the race and the scale it sits on. What matters more is the trend (is a horse improving or declining?) and the context behind a figure. A high number off a freak pace collapse is worth less than a slightly lower one earned in a true-run race.

How do speed ratings differ from official ratings?

Official handicap ratings are assessments of merit set by the handicapper, largely from the result and beaten margins. Speed ratings are derived from the clock and the conditions, so they can flag an improving horse, or a flattered one, before the official figure catches up.

Do speed ratings work for both Flat and National Hunt racing?

Yes. The principles are the same on the Flat and over jumps: normalise the time for the conditions and the way the race was run. Pace and going adjustments tend to matter even more over jumps, where tempo varies widely.

How should I use speed ratings on raceday?

Shortlist on the ratings, sanity-check the context behind each figure, overlay the pace map and draw, then look for improvers on a rising trend and short-priced favourites on a declining one, and bet where the price offers value.

What Is a Speed Rating?

A speed rating is a single number that expresses how fast a horse ran, adjusted so that performances at different courses, distances and going can be compared on one scale. A raw time on its own tells you very little: a quick time at a sharp track on firm ground is not the same as the same time on a stiff course in soft. A speed rating strips out that context so two runs you could never otherwise compare sit on the same yardstick.

At EquiAnalytix every horse racing speed rating is built from more than 20 years of UK and Irish form, normalised for the conditions on the day, so the number you read reflects merit rather than the accident of where and how a race was run.

Why Raw Time Isn't Enough

Raw times vary by track, weather and pace shape. Our ratings correct for those distortions so you are comparing like for like across courses and distances.

Normalised finishing time per distance
Going and surface adjustments
Pace profile (true-run vs false-run)
Course configuration effects
Draw bias (especially sprints and turning tracks)

How a Speed Rating Is Calculated

We begin with the raw finishing time, then layer a series of contextual adjustments on top. Each one answers the same question: would this time mean something different under different conditions?

Going & surface

The same time on firm and on heavy are not equal performances; we adjust for both.

Distance

Times are calibrated per furlong so sprints and staying trips share one scale.

Pace shape

A true-run race and a false-run, sprint-finish race produce very different raw times.

Course configuration

Stiff finishes, sharp tracks and undulations all leave their mark on the clock.

Draw position

Stall position can flatter or punish a time, especially in sprints and around turns.

Class & field strength

Beating a strong field matters more than the same time against weak rivals.

Weight carried

Weight is factored so a run under a big burden is not undersold.

How to Read the Numbers

Treat the figures as a relative scale, not a verdict. The trend across a horse's recent runs usually tells you more than any single number.

Spot the improver

76 → 82 → 88 signals a horse on the up that the market may not have caught yet.

Fade the hype

96 → 90 → 84 on a short-priced favourite often flags a vulnerable jolly.

Compare fairly

Judge an all-weather run at Kempton against a turf run at Newbury on the same scale.

Using Speed Ratings on Raceday

1
Shortlist on the ratings. Start with the top-rated runners to focus your attention.
2
Check the context. Was each figure earned in a true-run race, or flattered by a soft pace or a kind draw?
3
Overlay pace and draw. Match the ratings against the likely race shape and stall positions.
4
Find the trend. Back improvers on a rising line; be wary of favourites on a falling one.
5
Bet for value. Take a position only where the price is bigger than your assessment justifies.

Common Mistakes

Trusting one big figure from a freak run instead of the overall trend.
Reading the number without the pace, draw and going context behind it.
Comparing ratings from different providers as if they share a scale.
Backing the top-rated horse blindly, at any price, regardless of value.

Glossary

Speed Rating: Adjusted performance number enabling fair comparisons across races.
Going: The state of the ground, from firm to heavy, which alters times.
Pace Profile: The tempo/shape of a race (strong, even, or slow early pace).
Course Bias: Track tendencies favouring certain run styles or lanes.
Draw Bias: Systematic advantage/disadvantage from stall position.

FAQs

A speed rating is a single number that expresses how fast a horse ran, adjusted so performances at different courses, distances and going can be compared on one scale. It turns a raw time, which means little on its own, into a like-for-like measure of merit.
