Horse Racing Going Explained: Firm to Heavy, Irish 'Yielding' and Soft-Ground Horses

Home › Form Guide › Going Explained

By The Guv'nor · Last updated October 2026

Horse racing going explained in a nutshell: the going is the official description of how firm or soft the track is. British turf runs firm, good to firm, good, good to soft, soft and heavy (hard is hardly ever used). Ireland swaps good to soft for three "yielding" steps, and all-weather tracks run from fast through standard to slow.

The going in horse racing is one of the first things I check on a racecard, because a horse that loves one surface can be a different animal on another.

Horse racing going explained: firm to heavy in Britain and Ireland

In Britain the Clerk of the Course gives the official going. The BHA's General Instruction on the racecourse (the version I could open is dated 29 March 2014) allows only seven types of going on turf: hard, firm, good to firm, good, good to soft, soft and heavy. Watch the add-ons: "in places" (as in "Good to Firm (Firm in places)") means significant areas differ, and "watering" (still going on) or "watered" (finished) means significant watering in the previous 72 hours. The same instruction tells Flat courses to aim for good to firm and jumps courses for good.

Ireland uses its own words between good and soft. I couldn't find an official conversion between the two scales, so the British column below is my rough read of where each Irish term sits, not a ruling.

What does yielding mean in horse racing?

Yielding is Irish going with some give in it: softer than good, firmer than soft. The Jockey Club's glossary calls it an "Irish term to describe racecourse going that is soft", while plenty of British form guides treat it as good to soft. On the Irish ladder it sits slap bang in the middle, with good to yielding (good with a bit of cut) above it and yielding to soft below it.

A real example: how fast Irish ground can turn

Horse Racing Ireland's ground reports page logs each update with the time, rainfall and forecast. These are the reports for the Curragh's past meeting on 26 and 27 September 2026 (read on 5 October 2026).

Yielding to heavy in a little over 24 hours, the last jump inside an hour and a half on raceday morning. Killarney went from yielding to soft at 8.07am to soft by 1.36pm on 5 October 2026. Any form study, or Irish horse racing tips, read the night before was on the wrong ground.

Going stick readings explained

The GoingStick, developed by TurfTrax and Cranfield University, went into official going reports at 15 British courses in December 2003 (the Jockey Club's announcement). It measures penetration (the force needed to push the tip fully into the ground) and shear (the energy needed to pull the handle back to 45 degrees), and gives a reading on a scale of 1 to 15. Higher numbers mean firmer ground. The BHA says a reading has been required under the Rules of Racing since January 2009, at declaration stage and again on raceday.

The 2003 announcement printed a band for each going description. Later the BHA published the average reading logged against each official description at British courses from 2008 to 2013. Side by side, they don't line up.

Sources: Jockey Club press release, 2 December 2003 (bands); BHA "GoingStick Average Readings", British fixtures 2008-2013 (means; number of reports in brackets; split descriptions counted by the first word). N = 10,676 Flat and 8,945 jumps reports.

What jumps out at me:

• The averages sit well above the old bands. Heavy on the Flat averaged 5.7, which the 2003 index called good to soft. Recalibrated since or not, don't translate a reading with those bands.
• The steps are small. Flat good averaged 7.9 and good to firm 8.6, so half a point between declarations and raceday is a real change.
• Jumps tracks read lower for the same word from heavy to good, by 0.2 to 0.5.

The BHA's own note is the best advice going: the summary "is not an official scale and should not be used to give a specific indication of the Going at any individual course". Compare a reading with that course's own history. The HRI ground reports I read gave no GoingStick number, so for Irish cards the words are what you've got.

All-weather going: standard to slow, standard and fast

All-weather tracks race on artificial surfaces such as Polytrack and Tapeta, so the BHA instruction gives them five descriptions of their own: fast, standard to fast, standard, standard to slow and slow.

Standard means the surface is riding as normal for that track. Standard to slow means it's riding a bit slower than usual, so expect slower times; standard to fast is the opposite. My all-weather racing guide covers the tracks and surfaces one by one.

How the going changes results

Start with how often each ground turns up, because that's how much evidence a horse can ever build on it. These shares are my division of the BHA's 2008-2013 report counts above.

Good to soft or softer was the going for about one Flat report in four (25.1%) but nearly half of jumps reports (47.6%). Heavy on the Flat was rare (231 reports in six years), so few Flat horses ever get to prove themselves on it. The data is over a decade old, so take the shape, not the exact numbers. Either way, the ground deserves extra attention through the winter; my jumps season preview has the big dates coming up.

What changes on the day when the ground moves:

• Non-runners. Trainers pull horses when the ground goes against them. Under the Tattersalls Committee's standard terms, a race that drops from eight runners to seven goes from three places to two, and a handicap that drops from 16 to 15 goes from four to three (see my each-way betting guide). If you took a price, a late withdrawal can also bring a Rule 4 deduction on your winnings.
• Stamina and old form. Softer ground makes every trip more of a test, and a run on good to firm tells you less about a race on soft.

What I can't show you yet is how favourites behave by going. My favourites numbers come from Betfair SP files with no going field: across all ground, 35.0% of BSP favourites won (4,550 of 12,991 UK and Irish races, October 2025 to September 2026; more on how often favourites win). When I've matched going to those results, the split goes here.

Spotting a soft-ground horse

"Mudlark" gets thrown about on every wet Saturday. Check it rather than take it on trust:

1. Read the going beside every run and line the form figures up against it (how to read horse racing form walks through a racecard; horse racing abbreviations decodes the shorthand).
2. Count runs, not just wins. Wins and places out of runs on each ground is the honest picture.
3. Separate "unproven" from "can't handle it". A horse that's never raced on soft hasn't failed on it.
4. Check the mark. A soft-ground win off a low rating isn't the same as doing it off 10lb higher (handicaps explained).

A made-up worked example (not a real horse):

On the headline numbers it's a soft-ground horse: one win from two on soft or heavy (50%) against one from six on good to firm (17%). But two runs is nothing: flip one result and the "soft-ground horse" disappears. What the record does show is a horse that's run its race on every ground, placed or better in both soft runs. I'd call that "handles soft" and look harder at the price than the label.

How I use the going in my own betting

Look, I'm essentially a statistics/maths geek, so the first thing I ask about any "ground preference" is how many runs it's built on. Two good efforts on heavy is a hint. Ten runs is a pattern. Most horses sit somewhere in between, and the price has to pay me for that doubt.

The ground matters for my outsiders too. My system picks out horses that have won or come close off a higher weight or mark than they're running off today, and the obvious question with any of them is whether today's ground is anything like the ground that run came on.

When the going changes on the morning, I don't force it. If I'm not sure a horse will handle it, I skip it, and I'd tell you to do the same with any selection you're unsure about. The stake stays in points whatever the weather, because going all in on a feeling is how banks disappear. And some days there's simply nothing worth a bet: a stinky day for the ponies. Understanding that losers are a thing is the key to being a winner longer term; I'm after profit month to month, not a perfect strike rate. If you want that shortlist in your inbox, my premium tips come out most mornings.

Going questions people ask

Is yielding the same as good to soft?

Roughly. Ireland splits the band between good and soft into three steps where Britain has only good to soft. Yielding is the middle step, so "good to soft" is a fair shorthand.

What does good to soft mean?

Good ground with some give from rain: softer than good, firmer than soft. It's the most common jumps going after good in the BHA's 2008-2013 figures (22.3% of jumps reports).

What does good to firm mean?

Ground on the quick side of good. It's what British Flat courses are told to aim for, and it was the most common Flat going in 2008-2013 (40.2% of Flat reports).
