When you read a British horse-racing card, the race title will usually include a class.
You may see:
Class 1
Class 2
Class 5
Class 6
But what do these classes mean, how does a Group 1 differ from a Class 1 handicap and why does it matter when a horse moves up or down in class?
At Kevin Myles, we have been involved in independent on-course bookmaking since 1989. In this guide, we explain the British horse-racing class system and how it can help you understand the quality of a race.
What Does Class Mean in Horse Racing?
A race’s class provides a broad indication of its quality and the standard of horses expected to compete.
In simple terms:
Class 1 contains the highest-quality British races, while Class 6 generally contains races staged at a lower level.
The current structure broadly runs:
Class 1
Class 2
Class 3
Class 4
Class 5
Class 6
The class is normally displayed in the race title and on the racecard.
For example:
2:30 Newbury – Class 3 Handicap – 1 mile – Good
This tells you that:
The race begins at 2:30.
It takes place at Newbury.
It is a Class 3 contest.
It is a handicap.
It is run over one mile.
The going is officially described as good.
Is Class 1 the Highest Level?
Yes.
Class 1 contains the highest-quality races in British racing.
On the Flat, this includes:
Group 1 races.
Group 2 races.
Group 3 races.
Listed races.
Certain major handicaps.
Over Jumps, Class 1 includes:
Grade 1 races.
Grade 2 races.
Grade 3 races.
Listed races.
Premier Handicaps.
However, not every Class 1 race is equal.
A Group 1 or Grade 1 is at a higher level than a Listed race, even though both sit within the broader Class 1 category.

This is a broad guide.
The precise eligibility, ratings bands, weights and conditions are stated in the individual race conditions.
What Is a Class 1 Horse Race?
Class 1 represents the highest level of British racing.
This category includes major races contested by some of the best horses in training.
Examples of Class 1 contests include:
The Derby.
The 2,000 Guineas.
The 1,000 Guineas.
The Cheltenham Gold Cup.
The Champion Hurdle.
The Nunthorpe Stakes.
The Ascot Gold Cup.
Class 1 also contains Listed races and major handicaps, so the quality can still vary significantly within the category.
A horse moving from an ordinary handicap into a Group or Grade race is facing a considerable increase in class.
What Is a Group 1 Race?
A Group 1 is the highest category of Flat race.
These races are designed to identify the very best horses in a particular age, distance or sex category.
Group 1 races are generally run at level weights, although horses can receive allowances based on factors such as age and sex.
Major British Group 1 races include:
The Derby.
The Oaks.
The 2,000 Guineas.
The 1,000 Guineas.
The King George VI and Queen Elizabeth Stakes.
The Nunthorpe Stakes.
The Ascot Gold Cup.
Winning a Group 1 can considerably enhance a horse’s reputation and future breeding value.
What Are Group 2 and Group 3 Races?
Group 2 and Group 3 races sit immediately below Group 1 on the Flat.
The hierarchy is:
Group 1
Group 2
Group 3
Listed
A Group 2 remains a very high-quality race and may contain horses that have competed successfully at Group 1 level.
Group 3 races are one level below Group 2 but still form part of the Pattern system for leading Flat horses.
Group 2 and Group 3 contests can include penalties requiring previous winners at a specified level to carry additional weight.
What Is a Listed Race?
A Listed race is one level below Group 3 on the Flat.
Listed races are still part of the highest-quality area of the racing programme and carry Class 1 status.
They can provide:
A stepping stone into Group company.
An opportunity for horses dropping from Group races.
Valuable black-type form for breeding purposes.
A test for an improving horse moving out of handicap company.
A horse that wins a Listed race may next compete in a Group 3 or Group 2, although progression is never automatic.
What Does Black Type Mean?
You may hear people describe a horse as a black-type performer.
The term relates to performances in Group, Graded and Listed races.
In sales catalogues, qualifying performances are traditionally printed in bold or black type to highlight the horse’s high-level racing record.
Black type can be particularly significant when assessing the future breeding value of fillies and mares.
What Are Grade 1, Grade 2 and Grade 3 Races?
The term Group is generally used for leading Flat races in Britain.
The term Grade is used for high-quality Jump races.
The basic National Hunt hierarchy is:
Grade 1
Grade 2
Grade 3
Listed
Grade 1 is the highest level.
Examples include:
The Cheltenham Gold Cup.
The Champion Hurdle.
The Queen Mother Champion Chase.
The King George VI Chase.
The Supreme Novices’ Hurdle.
Grade 2 and Grade 3 races sit below Grade 1 while remaining high-quality Class 1 contests.
What Is a Premier Handicap?
A Premier Handicap is a leading Jump handicap carrying Class 1 status.
Unlike a level-weights Grade 1 race, horses in a Premier Handicap carry different weights according to their official handicap ratings and the race conditions.
These races are often highly competitive and can attract large fields.
A horse may therefore be competing in a Class 1 race without running in a Grade 1, Grade 2 or Grade 3 contest.
This is why you should check both the class and the race type.
What Is a Class 2 Horse Race?
Class 2 is immediately below Class 1.
It can include:
High-quality handicaps.
Conditions races.
Strong novice races.
Valuable maiden races.
Heritage Handicaps.
Open handicaps.
Class 2 handicaps frequently feature experienced and highly rated horses.
A runner moving from Class 4 or Class 5 company into Class 2 may face stronger opposition and potentially a more demanding race.
However, the horse may also be improving quickly enough to compete at the higher level.
What Is a Class 3 Horse Race?
Class 3 races contain good-quality horses operating below the elite and highest handicap levels.
They may include:
Competitive handicaps.
Novice hurdles or chases.
Maiden races.
Conditions races.
Veterans’ races.
A Class 3 handicap can contain experienced horses with strong form.
The difference between winning a Class 4 and competing successfully in Class 3 may come down to a horse’s improvement, handicap mark, weight, going, distance and strength of opposition.
What Is a Class 4 Horse Race?
Class 4 is a common middle level in British racing.
These races can include:
Flat handicaps.
Maiden and novice races.
Handicap hurdles.
Handicap chases.
Conditions races.
Many horses begin or build their careers at this level.
Class 4 races can be highly competitive, particularly when they contain lightly raced horses whose full level of ability is not yet known.
A Class 4 novice race can also produce horses that later compete at a much higher level.
What Is a Class 5 Horse Race?
Class 5 contains a large amount of everyday British racing.
It includes:
Lower-rated Flat handicaps.
Maiden races.
Novice races.
Handicap hurdles.
National Hunt Flat races.
Some classified races.
Class 5 does not mean the race will be easy to assess.
A lower class can contain several evenly matched horses, inconsistent runners or lightly raced horses with limited evidence available.
These factors can make the contest particularly competitive.
What Is a Class 6 Horse Race?
Class 6 generally contains lower-rated Flat handicaps and classified races.
The horses may have lower official ratings, but that does not necessarily make the race straightforward.
Class 6 races can be difficult because runners may:
Have inconsistent recent form.
Be returning from an absence.
Be trying a different distance.
Be racing on a new surface.
Have recently fallen in the handicap.
Be competing under more suitable conditions.
Have limited winning form.
A horse dropping into Class 6 may appear to be facing weaker opposition, but its recent form and current handicap mark still need to be considered.
Does a Higher Class Mean a Better Horse?
Generally, horses competing successfully in higher-class races have demonstrated a higher level of ability.
However, appearing in a higher-class race does not automatically make a horse superior to every runner in a lower class.
A horse may be:
Entered ambitiously.
Moving up before it is ready.
Returning from a break.
Better suited by different conditions.
Improving rapidly.
Dropping in class after losing form.
The level at which a horse has performed well is more informative than simply noting the highest class it has entered.
What Does “Moving Up in Class” Mean?
A horse is moving up in class when it competes at a higher level than in its previous race.
For example:
Class 5 → Class 4
or:
Listed → Group 3
Moving up in class normally means facing stronger opposition.
This may happen because the horse:
Won its previous race.
Has received a higher handicap rating.
Has shown considerable improvement.
Is being tested at a stronger level.
Is entered in a more valuable race.
Has conditions that connections believe will suit it.
A move up in class is not automatically negative.
An improving horse may be capable of progressing through several levels.
What Does “Dropping in Class” Mean?
A horse is dropping in class when it contests a lower-level race than previously.
For example:
Class 3 → Class 4
or:
Group 3 → Listed
A class drop can be significant because the horse may face less accomplished opposition.
However, it does not guarantee an improved performance.
The horse could be dropping because:
Its recent form has been disappointing.
Its handicap rating has fallen.
Connections want to find a more suitable opportunity.
It is returning from an absence.
It has struggled at a higher level.
The race conditions are more appropriate.
Always consider why the horse is dropping in class rather than assuming the change makes it certain to win.
Does Race Class Determine the Weight?
Not by itself.
The race type and conditions determine how the weights are allocated.
In a handicap, horses carry different weights according to their official ratings and the race conditions.
In many Group, Graded and Listed races, weights are governed by:
Age.
Sex.
Previous wins.
Penalties.
Allowances.
The specific conditions of the race.
Two races can share the same class while using very different systems for allocating weight.
Read What Is a Handicap Horse Race? for a full explanation of ratings and weights.
Is a Class 2 Handicap Better Than a Class 2 Novice Race?
They share the same broad class, but they are different types of race.
A Class 2 handicap contains horses carrying weights linked to their official ratings.
A Class 2 novice race is restricted according to the novice conditions and may include horses with considerably less racing experience.
The races cannot be compared solely by looking at the class number.
You should also consider:
Race type.
Eligibility conditions.
Age restrictions.
Distance.
Going.
Prize money.
Official ratings.
Previous level of form.
What Is the Difference Between Race Class and Official Rating?
Race class describes the level of the contest.
An official rating assesses an individual horse’s ability.
For example, a Class 4 handicap may be restricted to horses within a particular ratings range.
A horse’s rating helps determine:
Whether it is eligible.
The weight it carries.
Which handicap races are appropriate.
The race class and official rating are connected, but they are not the same thing.
Can a Horse Compete Outside Its Usual Class?
Yes.
A trainer may enter a horse at a higher or lower level depending on:
Eligibility.
Handicap rating.
Current form.
Race conditions.
Ground.
Distance.
Available opportunities.
Prize money.
The strength of the expected field.
An improving horse can rise through the classes, while a horse whose form has declined may gradually drop into lower-level races.
Why Does Class Matter When Reading Form?
A finishing position does not tell the complete story.
Consider two horses:
Horse A finished second in a Class 2 handicap.
Horse B won a Class 6 handicap.
Horse B has the more recent victory, but Horse A may have faced considerably stronger opposition.
That does not automatically mean Horse A will beat Horse B. Weight, distance, going and current form still matter.
However, understanding class gives important context to previous results.

Does Class Affect Horse-Racing Odds?
Yes, class can influence how a betting market is formed.
Bookmakers and customers consider:
The level of the horse’s previous races.
Whether it is moving up or down in class.
How it performed against stronger or weaker opposition.
Its official rating.
The weight it carries.
Whether the new race conditions are suitable.
A horse dropping in class may shorten in price if the market believes it will benefit from weaker opposition.
An improving horse moving up in class can also attract support.
Price movement remains an expression of market opinion and does not guarantee the outcome.
How Do You Find the Class on a Racecard?
The class normally appears in the race heading.
For example:
3:15 Kempton – Handicap Stakes (Class 5)
The racecard may also display:
Distance.
Age restrictions.
Ratings band.
Race type.
Prize money.
Going.
Number of runners.
Check the full race conditions rather than relying only on the class number.
Horse-Racing Classes Explained: The Simple Version
If you remember nothing else from this guide, remember:
British racing broadly runs from Class 1 to Class 6.
Class 1 contains the highest-quality races.
Group 1 is the highest level on the Flat.
Grade 1 is the highest level over Jumps.
Listed races sit below Group and Graded races.
Class 2 to Class 6 cover progressively different levels of racing.
Moving up in class normally means facing stronger opposition.
Dropping in class can provide an easier opportunity, but does not guarantee success.
Race class and a horse’s official rating are related but different.
Always consider the race type and conditions alongside the class.
