Margins lie. A horse that wins by three lengths after a soft lead in slow time isn't necessarily three lengths better than the field — and a horse beaten two lengths after running the fastest closing 600m of the race might have been the best runner on the track.
That gap between what happened and what it meant is what sectional times are for. They strip out the pace narrative and tell you how fast a horse actually travelled at each stage of the race.
This guide explains every sectional metric on the FormRace race page, what it really measures, and how to use it without falling into the common traps.

What a sectional time actually is
A sectional is the time taken to cover a specific portion of a race — measured by GPS or by timing-beam splits embedded in the track. The most common splits in Australian flat racing are:
These are the splits FormRace surfaces because they correlate most strongly with finishing ability over the next 1000m–2400m of racing.
A faster sectional means the horse covered that segment in less time. Lower is faster. A 33.40s last-600m is genuinely strong; a 36.80s last-600m means the horse was either tiring or ridden quietly to the line.

The "Avg L600" column — your first read
The first number to look at is Avg L600 — the average of a horse's recent last-600m sectionals. This is the column we sort the table by, fastest at the top.
Why this one? Because the closing 600m is where most thoroughbred races are decided in Australia. Pace is rarely truly even — fields settle, fan out around the turn, and the horse with the most petrol in the tank from the 600m point onwards wins more races than any other single profile.
How to read the colour:
The 0.3-second threshold isn't arbitrary. In a 600m segment, 0.3s is roughly two lengths — small enough to be sample noise on a single run, big enough across multiple recent starts to indicate a genuine difference in late-race ability.
Why the average and not the best?
We show Avg L600 because consistency is what predicts. A horse with one freakish 33.0s split and four 35.5s splits has an average that fairly represents what you can expect today. Its Best L600 (next column) tells you the ceiling — what the horse is capable of when conditions line up.
Use the gap between Avg and Best as a tell: a small gap means a reliable closer. A huge gap means a horse with a pattern — it produces the big finish only when something specific happens (soft lead, wet track, big field).

Early vs Late speed — the running style fingerprint
When sectional speed data is available, we surface Early and Late speed instead of the secondary L600 columns. Both are in kilometres per hour, averaged across the horse's recent starts.
The relationship between the two is the single most useful piece of profiling on the page.
Late > Early by 2+ km/h → CLOSER. This horse accelerates as the race progresses. It's the profile of a back-marker that picks up the field, or a midfielder that ranges up wide on the turn. Closers thrive when the speed crumbles in front of them.
Late ≈ Early → ON PACE. Sustained pace throughout. These horses lead, sit handy, and refuse to stop. They win when the early tempo isn't reckless and they get to dictate.
Late < Early by 2+ km/h → FADER. The horse is fastest when fresh and slows in the closing stages. Faders only win when they get an unchallenged front-running ride and the closers behind them mistime their runs.
A 2 km/h gap might sound small, but over a 600m closing section it's the difference between a horse pulling away from rivals and being run down by them.

Reading running-style tags in context
Every runner gets one of three tags in the Style column: CLOSER, ON PACE, or NEUTRAL (insufficient signal in either direction).
These tags are descriptive, not predictive on their own. A CLOSER tag tells you what this horse does. To turn it into a betting read, combine it with the speed map for the race:
The Speed Map module on the race page does this job for you — it overlays the predicted positions on a track diagram so you can see the pace structure at a glance.

The expanded history — what to actually look for
Click any runner in the sectional table to expand their last-start history. You'll see the date, venue, distance, finish position, L600/L400/L200 splits, and (where available) the early/mid/late speed bars.
A few patterns worth hunting for:
1. Sectional improvement on a fade. Runner finished 6th, beaten 3 lengths, but ran the fastest L400 in the race. That's a horse that hit the line strong despite the result — often a "next-time-out" play.
2. Distance-specific class. A horse that runs 33.5s L600 over 1400m but 35.0s over 1600m doesn't stay. Don't be fooled by gaudy headline times if the distance doesn't match.
3. Sectional decay. A horse whose L600s have steadily lengthened across its last four starts (e.g. 33.4 → 33.9 → 34.5 → 34.8) is going the wrong way regardless of finish positions. Avoid.
4. Speed profile bars. The mini visualisation under the history shows Early/Mid/Late speed as coloured bars. A green-dominant final bar (Late > Early) confirms the closer pattern. A red-dominant final bar (Late < Early) flags a horse that finds the line too long.

Common mistakes when using sectionals
Mistake 1 — Comparing across tracks without adjustment. A 33.4s L600 at Flemington (a long, fair galloping straight) is different to a 33.4s at Caulfield (tight turn, short straight). Track configuration and gradient matter. Use sectionals to compare within a meeting first.
Mistake 2 — Ignoring track condition. Wet tracks and heavy tracks produce slower sectionals across the board. A 34.0s L600 in the Heavy 9 looks slow next to a 33.0s L600 on the Good 4, but it might actually be the more impressive run. Always cross-reference with the track condition.
Mistake 3 — Treating sectional splits as direct evidence of merit. A horse that "ran the fastest L600" of the meeting from last didn't necessarily run the best race — it might have had every favour in a steadily-run event while the leader carried the weight of being honest. Sectionals are evidence, not verdict.
Mistake 4 — Over-weighting one freakish run. A single fast L600 in a horse's last five starts is information, not a signal. We surface the average for this reason. One outlier is noise; a pattern across multiple runs is signal.

How FormRace uses sectionals in the model
The XGBoost model that produces every prediction on the site takes 18 sectional-derived features as input — including average L600, best L600, distance-matched L600, late-speed ratio (late ÷ early), and acceleration deltas across the closing splits.
These sit alongside 186 other features (form, weight, jockey, trainer, barrier, market signals, pedigree, ratings) and are combined with non-linear interactions the model learns from historical data.
The sectional metrics on the race page are the human-readable view of what the model already considers. Use them to sanity-check the model's selections, build conviction in plays you're already on, and recognise the running-style story behind a race that the bare odds don't tell.

Quick reference
| Term | Meaning | Read |
|---|---|---|
| L600 | Last 600m time | Lower = faster finish |
| L400 / L200 | Last 400m / 200m | Sustained late acceleration |
| Avg L600 | Average across recent starts | Reliable expectation |
| Best L600 | Fastest ever recorded | Ceiling under right conditions |
| Early speed | Avg km/h, opening stages | Pace pressure ability |
| Late speed | Avg km/h, closing stages | Closing power |
| E/L ratio | Late ÷ Early | > 1.0 = finishes faster than starts |
| CLOSER | Late > Early by 2+ km/h | Needs honest pace in front |
| ON PACE | Late ≈ Early | Wins by leading or sitting handy |
| Fader | Late < Early by 2+ km/h | Wins only with an easy lead |
Sectionals aren't magic, and they don't replace form, class, or market intelligence. But used well, they're one of the few pieces of racing data that genuinely reveals what happened inside a race rather than just summarising the result. That's why they sit at the centre of how FormRace profiles every runner.
