Horse racing going explained: from firm to heavy

What is the British going scale from hard to heavy?

British turf going runs hard, firm, good to firm, good, good to soft, soft and heavy. Firmer ground rides faster; softer ground is slower and more tiring because hooves sink into it.

Each step describes how much give there is in the turf. On firm ground a hoof barely marks the surface and races are run at a fast pace. On heavy ground the hoof sinks deep, each stride takes more effort and races become a slog in which stamina counts for more than speed. Hard ground is so rare that most courses would abandon rather than race on it.

Clerks often add qualifiers such as good to soft, good in places, when the ground varies around the course. Separate descriptions can also be given for the hurdles and chase courses, or for the straight and round courses, because they are different strips of turf that dry and drain at different rates.

What do yielding and yielding to soft mean in Irish going?

Yielding is an Irish description for ground with clear give, softer than good but firmer than soft, sitting roughly where good to soft sits in Britain. Yielding to soft is a step softer again.

Irish going uses a longer scale with more steps in the middle: good, good to yielding, yielding, yielding to soft, soft, soft to heavy and heavy. When an Irish horse runs in Britain, treat good to yielding as close to the softer side of good and yielding as close to good to soft. Form on each should be compared by the times and the way races were run, not the word alone.

What do standard, fast and slow mean on the all-weather?

All-weather going describes how the synthetic surface is riding: standard is the norm, standard to fast or fast means quicker than usual, and standard to slow or slow means more testing.

Synthetic tracks such as Polytrack and Tapeta change with temperature, moisture and how the surface has been harrowed. Weather and maintenance can make them ride quicker or slower than usual. Most all-weather meetings are declared standard, so a change from standard is worth noting when comparing times.

Who decides the official going and when can it change?

The clerk of the course declares the official going, using a walk of the track, GoingStick readings, rainfall and experience of the course. The going can be changed before racing or between races.

The going is published in the days before a meeting, updated on the morning of racing and changed again if rain arrives or the ground dries. A change from good to good to soft on the day can bring non-runners from horses that need a fast surface. Many courses water the ground in dry spells to keep it safe, which is why summer going is often good to firm rather than firm.

Watering is not always even, and a course that has been watered heavily can ride slower than its description suggests. Race times on the day, compared with standard times, are the best check on whether the declared going was accurate, and they often lead to the going being changed during the afternoon.

What does the going do to race times and stamina?

Softer going slows every horse down and turns races into stamina tests; firmer going quickens the pace and rewards speed. The same horse can run to very different levels on different ground.

On soft or heavy ground a 2 mile chase can take many seconds longer than on good, and horses who stay further than the trip come to the fore. On fast ground, speedier horses can hold their position and front runners are harder to peg back. Some horses have a clear preference: a high, round knee action usually copes with soft ground, while a low, sweeping stride is often best on top of fast ground.

How do favourites perform on each going description?

The chart on this page shows the jumps favourite win rate on each going description, and the data page adds flat splits

Favourites in British and Irish jumps races won 35.6% of the 392 heavy-ground races in 2025/26, against 37.5% of 1,913 on good. Over ten seasons the heavy-ground figure is 36.8% from 5,108 races. Testing ground tends to shrink the number of horses who can be competitive, which helps a proven soft-ground favourite.
