You can probably name the favourite, the top-rated horse and the in-form jockey before you have looked at a card. Fewer people can say which horse will be in front after a furlong. That is where pace ratings earn their keep.
Pace is not a soft, intuitive idea. It is measurable and rateable, and over thirteen years of UK racing the top pace-rated horse on Race Advisor’s master file has a strike rate almost 50% higher than the bottom of the field. Knowing that the market has already noticed is just as useful, because it shows you where to look next.
This is the third and final part of the pace mini-series. The first looked at how pace affects horse racing results. The second covered track pace bias. This one is about the numbers themselves: what a pace rating does, how Race Advisor builds one, and what the data says about using it.
What are horse racing pace ratings? They score how a horse runs early in a race: whether it leads, presses, sits mid-pack or closes. Race Advisor’s Total Pace Score is built from in-running performance across a horse’s recent runs. In an earlier analysis of over 162,000 UK runners since 2013, the horse with the top pace rating in its race won 13.9% of the time, against 9.5% for runners ranked fourth or lower. The market reads this signal sensibly, so pace ratings work best as a tool for reading the shape of a race.
What does a pace rating actually measure?
A speed rating tells you how fast a horse finished a race. A pace rating tells you where in the race it was doing the running. Those are different questions.
Every UK race has four broad pace types in it. Leaders go to the front and try to keep it. Early Pressers sit on the leader’s flank, ready to pounce. Mid-Pack runners track from behind. Closers wait, then sweep through late. A horse is rarely committed to one style for life, but most have a clear preference, and that preference shapes the first half of the race.
The pace rating is the numeric version of that preference. A high score means the horse has consistently put itself near the front. A low score means it has dropped in early and come from off the pace. Once every horse in a race is scored, you can read the race shape before it has been run.
How does Race Advisor build pace ratings without sectional times?
Sectional times (the time a horse takes over each section of the race) are not publicly available across UK racing the way they are in some other countries. So a UK pace rating has to be built from what we do have, which is the in-running commentary.
The race readers write a sentence describing each horse’s involvement: tracked leaders, led, chased leader, raced in midfield, held up in rear, ran on late. Those phrases follow conventions tight enough that, with enough volume and a consistent rule book, you can convert them into a pace category and then into a number.
Race Advisor’s Total Pace Score does that mechanically. It reads each horse’s recent in-running positions, weights them by recency and gives a single number for the horse’s pace tendency. It is comparable across horses and races. The same machinery produces an Avg Pace Last 3 Races figure, a tighter window for horses whose style may have shifted.
It is built on real race events, refreshed every day, and refined over 13 years of UK racing.
What does the data say about the top pace-rated horse?
The most useful question to ask of any rating is whether the horse it puts top of its race wins more often than the rest. Pace ratings pass that test cleanly. Across over 162,000 UK runners with a valid pace rating since 2013:
- The top pace-rated horse won 13.9%.
- The second-ranked won 12.4%.
- The third-ranked won 11.9%.
- Everyone ranked fourth or lower, the bulk of the field, won 9.5%.
The gradient is clean, and it holds by race type. The top pace-rated horse won 13.6% on Flat turf (61,567 runners), 12.6% on the All-Weather (39,400), 14.1% over hurdles (36,012) and 16.5% in chases (21,642). Pace ratings were most useful in chases, which is an observed pattern worth watching.
By class, the signal is strongest where fields are largest and the form book is busiest. In Class 3 and Class 4 handicaps the top pace-rated horse won 15.7% across more than 54,000 runners. In Class 1 it was 12.5%, where the market knows the runners best.
Field size is the biggest gradient of all:
- Fields of seven or fewer: 20.2% across over 48,000 runners.
- Fields of eight to ten: 12.8%.
- Fields of fifteen or more: 6.4%.
Pace ratings give their strongest strike rate where the race shape is simplest, which makes small fields a good place to start reading them.
Where do pace ratings point towards value?
A high strike rate is useful when it comes with a fair price, so it helps to know where the price and the rating line up and where they drift apart. Across every level of pace score and every race type, the A/E ratio (actual winners divided by the winners the odds implied) for the top pace-rated horse sat at roughly 1.00 at Betfair SP, the exchange’s closing price. In other words, the horses that win more also start at the right kind of prices.
Two conditions stand out from that picture:
- Heavy ground. The top pace-rated horse won 15.9% of 8,545 runners, with an A/E of 1.04. A possible reason is that heavy going tests off-pace runners hard, though the figures show the result, not the cause. An A/E of 1.04 is a modest gap from a slice of the data, so it is a pointer to look closer rather than a promise.
- Races projected to be run at a slow pace. The top pace-rated horse won 14.9% of 8,176 runners, with an A/E of 1.04. When only a few horses want to go forward, the rating top gets there, controls the race and starts at a price that mildly under-rates that control.
These are the two places where it pays to look hardest. Everywhere else, take the rating as strong information about race shape and look for your value from other angles.
How do you use pace ratings in your selection process?
Treat the rating as a shape, not the final answer. It tells you who is likely to control the race, and that changes how every other piece of evidence on the card reads. A speed rating earned by a horse that led every yard means something different from the same figure earned by a horse that came from last. Pace is the context that makes the speed figure usable.
A simple order works well:
- Use the pace rating to find the likely race controller.
- Check that horse’s price against your own odds line (the prices you would make each horse) and other angles such as PR Rank (Race Advisor’s ordering of the field) or the Race Predictor (our win probability for every horse).
- If the field is small, the ground is heavy or the projected pace is slow, give the rating top extra weight.
- Otherwise, use pace to read the race and find your value elsewhere.
One technical note. When the top horse by Total Pace Score is not the top horse by Avg Pace Last 3 Races, follow the Total Pace Score. Across 20,646 runners where those two measures disagree, the rating top won 13.7% and the three-race history top won 11.5%. The broader rating steadies you when recent runs mislead.
What is the practical takeaway?
The top pace-rated horse wins close to one in seven races on average, one in five in small fields, and carries a real value edge on heavy ground. Everywhere else it is good information at a fair price, and that is exactly the kind of tool you want in a routine you can trust.
Reading a card with pace in mind lets you see a race the way it is likely to unfold, and that habit compounds. Race Advisor’s Speed and Pace tab shows the ratings for every UK race, alongside speed ratings in horse racing and the race shape. To try it on the next race off, open today’s race cards.
