British and Irish racing: how they differ

How is Irish racing organised differently from British racing?

Ireland splits the job between Horse Racing Ireland, which runs fixtures, funding and prize money, and the Irish Horseracing Regulatory Board, which makes and enforces the rules, whereas the BHA does both in Britain.

The funding model differs too. Irish prize money is supported by the government's Horse and Greyhound Racing Fund, paid through Horse Racing Ireland, while British prize money relies more on the betting levy, racecourse media rights, sponsors and owners' entry fees. That difference is one reason Irish prize money per race is often reported as higher than in Britain.

Horses, jockeys and trainers move freely between the two countries. Irish-trained horses run at every major British festival, British-trained horses run in Irish big races, and form lines cross the Irish Sea every week, so understanding both systems helps when a horse switches country.

How many racecourses does Ireland have?

Ireland has around 26 racecourses across the island, including Down Royal and Downpatrick in Northern Ireland, with Dundalk the only all-weather track and the Curragh, Leopardstown, Punchestown, Fairyhouse and Galway among the best known.

Many Irish courses stage both Flat and jumps racing, and several are small, rural tracks with a handful of fixtures a year. Galway's summer festival in late July runs for seven days, one of the longest meetings in either country. Because Dundalk is the only synthetic track, the Irish winter Flat programme is concentrated there, whereas Britain spreads winter Flat racing across six all-weather courses.

Do Irish meetings mix Flat and jumps races on the same card?

Often, yes. Irish cards frequently mix codes, with Flat races, hurdles, chases and bumpers at the same meeting, whereas British meetings are nearly always all Flat or all jumps.

A typical Irish mixed card might open with a maiden hurdle, include Flat handicaps in the middle and finish with a bumper. That makes Irish cards less predictable to read at a glance, so check the race type for every race rather than assuming the whole meeting is one code.

Are Irish handicap marks the same as British official ratings?

No. Irish handicap marks are set by Irish handicappers and British official ratings by BHA handicappers, and although both use pounds on similar scales, a horse can hold different marks in each country at the same time.

When an Irish-trained horse runs in a British handicap, the BHA handicappers give it a British mark based on their own reading of its form, which can be higher or lower than its Irish mark. Big festival handicaps often turn on that difference. Britain and Ireland also publish joint international classifications of the top horses, which helps keep the upper end of the two scales broadly aligned.

How have Irish-trained horses performed at Cheltenham?

Irish-trained horses have won more races than British-trained horses at most recent Cheltenham Festivals, with the biggest Irish yards sending deep teams of high-class jumpers to the meeting each March.

The Irish strength comes largely from a small number of powerful yards. Bigger Irish fields at home mean horses often arrive battle-hardened, and the Irish programme of valuable mid-winter races gives trainers clear stepping stones to March. When comparing form, weigh the Irish races by their depth rather than their raw field size.

How should you read Irish form when a horse runs in Britain?

Judge Irish form by the quality of the race rather than its raw size, check the horse's Irish mark against its new British rating, and note whether it has handled the ground and type of track it meets in Britain.

An Irish maiden hurdle with twenty runners may contain only a handful of serious horses, while a small Leopardstown Grade 1 can be as deep as any race in either country. Irish tracks vary from sharp, tight circuits to galloping ones like Punchestown and Fairyhouse, so a horse's style of track matters when it switches to Cheltenham, Aintree or a British Flat course.

Pay attention to the trainer too. The biggest Irish yards send runners to British festivals every season, so a yard's record with horses running in Britain is worth checking alongside the horse's last Irish run.

How big is Irish racing in the results data?

Ireland runs fewer races than Britain, but its jumps fields are bigger: 11.4 runners on average in 2025/26 against 7.9 in Britain, from 1,503 Irish and 3,538 British jumps races.

Bigger fields change the numbers. Over ten seasons the figures are 34.2% for Ireland and 36% for Britain, and the table on this page updates as the current season unfolds.
