The clock tells you half the story at most. A final time says how long the race took. It says nothing about how the race was run, and on a British track that gap is exactly where the value hides. A strongly-run race and a tactical crawl can clock times a fifth of a second apart and mean entirely different things about the horses involved. Sectional times are how you tell them apart. They break a race into its segments, usually furlong by furlong, so you can read where the pace went, who spent energy and when, and which horses the bare result has flattered or short-changed. Most punters read the finishing order. The sharper money reads the shape of the race that produced it.

What a sectional time actually is

A sectional time is simply the time a horse takes to cover one part of a race rather than the whole thing. On the Flat that is usually each furlong. Over jumps it can be taken between obstacles. String the segments together and you get the profile of the race: fast early and slow late, slow early and fast late, or an even gallop the whole way.

The reason it matters is physical, not cosmetic. A horse has a finite tank. Go too hard too early and it pays for it later, losing more time at the finish than it ever gained at the start. Dawdle early and no amount of late sprinting buys that lost time back. So two horses can post the same final time off completely different races, and only one of them may have run anywhere near its true level. The final time tells you what happened. The sectionals tell you how. And the how is what you are betting on next time.

Finishing speed percentage, the one number worth learning

If you take one figure away from all of this, make it finishing speed percentage, or FSP. It measures how fast a horse ran its closing section compared with its own average speed across the whole race. Over 100 means it finished faster than its race average. It was quickening. Under 100 means it was slowing through the line.

Mind the window. The closing section is not the same length everywhere. On the Flat the providers typically measure the final two furlongs up to around a mile, the final three furlongs beyond that, and the final four furlongs over jumps. An FSP only means something once you know which closing stretch it was built from, so always check what you are being shown.

And 100 is not a magic line. This is where most people come unstuck. How fast is fast depends entirely on the track. Around the round mile at Ascot a par finish sits near 101 per cent. Down the Derby course at Epsom, where the run to the line is downhill, par is closer to 108. Up Beverley’s stiff final three furlongs, into the collar, par is usually below 100. Read an FSP without knowing the par for that course and trip and you will back tired horses for finishing fast and pass over good ones for finishing slow. The number is only useful measured against its par.

Reading the shape of a race

Once you can read the splits, every race resolves into one of a few shapes, and each shape rewards a different kind of horse.

The truly-run race. An even or strong gallop throughout, a real test of stamina. Closing speeds fall away, FSPs sit below par, and the winner is usually a horse that saw out every yard. Hold-up horses get a fair crack. Front-runners who went too hard get found out.

The tactical crawl. A slow early pace that turns into a dash. FSPs run high because the whole field is quickening off a steady tempo. This shape rewards position and a turn of foot rather than stamina, and the horses who got first run are flattered. A big closing sectional here tells you far less than it looks.

The over-cooked gallop. The leaders go off too hard, the race falls apart, and horses come from the clouds to pick up the pieces. The closers look brilliant. Often they only look it because the pace handed it to them.

From those shapes fall the four horses worth marking. The pace-inconvenienced closer, who finished strongly in a race run nothing like to suit, is the genuine eye-catcher, the one the result undersold. The efficient front-runner, who made all without ever emptying the tank, is the leader worth backing again. The flattered closer, who only finished well because the leaders cut their own throats, is the trap. And the track-position winner, who controlled a steadily-run race from the right spot, may have won on tactics rather than merit, and is often worth taking on next time at a short price.

The mistake almost everyone makes

Here is the most common sectional error there is: spot the fastest closer, back it next time. It is the closing-speed version of backing the biggest stride, and it loses money the same way.

A fast closing sectional is worth something only once you know the shape of the race did not gift it. The clearest way to see that is two horses who run an identical closing split. In the Lester Piggott Handicap at Epsom, two runners came home with exactly the same final three furlongs, 34.46 seconds each. One did it with the run of the race, handy and on the bridle, never out of his comfort zone. The other did it from seventh, making a 10.85-second move to force his way into contention before just flattening out near the line. Same number on the clock. Two completely different runs. The horse who did it the hard way ran the better race by a street, and the bare result would never have told you so.

So the order of operations is fixed, and it is the whole discipline in a single line: read the shape of the race first, then judge the horse. A closer’s sectional is bullish only if the shape did not hand it to him. A front-runner slowing late is no worry if the field slowed more. Build the race, then weigh the horse against it.

Reading it on a real race

Put it together on an actual race. A mile novice at York. The early furlongs tick by in 14.42, 13.48, 13.85 and 13.41 seconds, a steady, almost idle tempo. Then the winner changes gear: 11.85, 11.10, 10.76, and home in 11.48. The first half-mile took 55.16 seconds, the second 45.19. The closing three furlongs came back in 33.34. The finishing speed percentage was a colossal 113.58.

Read it naively and it is a monster. Fastest finisher on the card, back it blind. Read it properly and it is a strong horse whose breathtaking sectionals were half-built by the crawl in front of it. The conclusion is conditional, not a blank cheque. If next time the horse can again grab a prominent pitch and dictate, that turn of foot is a serious weapon. Drop it into a true end-to-end gallop, where the dawdling first half never happens, and the same closing burst may simply not be there to use. Strong horse, conditional bet. That distinction is exactly what a sectional read buys you and the bare result never could.

Where to find them, and what they cost

The good news, and it is genuinely recent, is that the best of this is now free. Racing TV opened its RaceiQ data to users in 2025: sectionals, pace graphs, cumulative time off the leader, par sectionals, and a time index that scores a race against its expected winning time. At The Races has carried sectionals from every British course since the industry pooled its data into one database in 2024. Timeform still sells deeper archives in spreadsheet form for anyone wanting to build their own model, with its own finishing-speed figures layered on top.

It was not always this easy. Sectionals were sparse and sporadic in Britain before about 2014. At The Races put pace and sectional data on its website in 2016, Wolverhampton became the first British track to show it live on screen in 2017, and official electronic timing for jump racing did not arrive until Cheltenham in 2019. The single all-British database only landed in 2024. If you remember sectionals being a specialist’s toy, you remember right. They are a mainstream tool now.

One honest health warning. The figures come from lightweight GPS trackers in the saddlecloth, the same feed that produces stride data. GPS is not millimetre-perfect. Relative positional error can run to around half a length, there is no single industry standard for how the data is collected, and the older archives were timed by hand off the television pictures. Treat the numbers as a sharp guide rather than gospel, and do not assume one provider’s splits are interchangeable with another’s down to the hundredth of a second. The edge is in the picture they build, not in the third decimal place.

How sectionals fit with the rest

None of this replaces the form book, and none of it is a crystal ball. What it does is correct the lies the clock and the placings tell on British tracks, where gradients, bends and tactics scramble the bare numbers more than almost anywhere on earth. Read the shape first. Mark the horse who ran better than it finished, fade the one who finished better than it ran, and wait for the market to misprice the difference. That gap is the whole game.
