Irish Trainers in UK National Hunt Racing

As we start a New Year, I want to examine the performance of Irish trainers when they send runners to the UK, writes Dave Renham. The focus of what follows is National Hunt racing, and I have taken data going back ten years, to 2015. Profits/losses are calculated to both Industry SP and Betfair SP.

Now, I am sure virtually everyone reading this will be aware of the excellent record of Irish trainers versus the British trainers at the Cheltenham Festival in recent years. So let's begin by reviewing this. Subsequently, I will delve deeply into the broader picture to see if there are any angles that, as punters, we may be able to take advantage of.

Cheltenham Festival

This four-day feast of racing will be upon us sooner than we think – March may be two months away, but the time soon flies by. Below is an overall table directly comparing the Irish trainer record at the Cheltenham Festival with their British counterparts.

 

 

It's hardly breaking news, but the Irish have been so dominant in this time frame; they have a much higher strike rate - well over double - and in terms of returns they have trounced the British in at both SP and BSP. It should be noted that Irish trainers outperformed British ones in the ten years prior to that (2005 to 2014), too, but the gap was closer, certainly in terms of win percentage (Irish won 7.9% of races compared to 4.6% for the British).

 

It's time now to start a deeper dive into the overall Irish performance. To begin with here are the stats for all Irish runners in the UK since 2015:

 

 

As the table indicates, there have been blind losses to SP of around 17 pence in the £, but a small 4p return to BSP. Taking the Cheltenham Festival out of the equation produces a small loss to BSP.

Time to drill down into the Irish / UK performance across different parameters...

 

Performance by Year

From this starting point I am going to look at some yearly data. For this I have used a method based on a Nick Mordin idea that I've previously used in recent draw bias articles; this approach helps to avoid individual year fluctuations which can make possible performance changes harder to pick up. I am using rolling four-year timeframes to help spot any patterns. Here are the four-yearly data in terms of returns to BSP.

 

 

The graph shows each four-yearly time frame has produced a profit to BSP which is clearly noteworthy. However, the last couple of years (2023 and 2024) have been losers, hence the recent drop in the 2021-2024 figures. It looks as though the market has now fully 'cottoned on' to current Irish dominance.

Here are the A/E indices using the same principle:

 

The highest A/E index of 0.95 was seen in the period from 2018 to 2021 which coincides with the best period in terms of Betfair SP returns. Also, the recent BSP drop off is mirrored here.

Taking this performance as a whole, the stats are impressive. Irish raiders have consistently made punters money over the past ten years if betting on the exchanges. Of course, there are plenty of big prices that help to inflate these results but, even so, the results are highly noteworthy.

 

Performance by Course

We have seen some course data already in terms of Cheltenham, and its Festival in March. Below are the overall Cheltenham course figures along with any other course that has seen 100 or more Irish runners during this ten-year time frame.

 

 

All of the Cheltenham BSP profit was procured at the Festival. A very small loss has occurred when combining all other Cheltenham meetings together.

In terms of the other courses Aintree is one to mention: runners at the Liverpool track have done extremely well considering the BSP profit is not badly skewed by big priced winners. Indeed, focusing on Irish runners at Aintree priced at 8/1 or less (industry odds), they would have produced a profit to both SP and BSP. Specifically, 57 of them won from 246 qualifiers (SR 23.2%) for an SP profit of £21.86 (ROI +8.9%); to BSP profits were £53.19 (ROI +21.7%). As you would expect a big proportion of these runners ran at the Grand National meeting in April.

Of the lower profile courses, Perth’s positive BSP figures are entirely down to one 200/1+ BSP winner, while Cartmel’s figures are not as bad as you may initially think. When concentrating on horses priced 8/1 or less at SP, Cartmel runners have also seen a small profit to BSP to the tune of £10.05 (ROI +5.2%). The outsiders at Cartmel have been the ones to avoid with 0 wins from 75 for horses priced 14/1 or bigger.

 

Performance by Race type

I would like to compare chases, hurdle races and bumpers (NH Flat) next. Here are the splits:

 

 

 

Hurdle races have produced a healthy profit to BSP, although as one would expect this has included a few big odds successes. There have been five wins at 100/1+ BSP to be precise and all hurdlers priced in three figures have combined to produce around 75% of the hurdling profit. Having said all that, six of the ten years has seen a blind hurdling profit to BSP with two of the four losing years showing very small losses. Focusing on shorter priced runners of 12/1 or shorter would have seen a break-even scenario. Hence, it is fair to say Irish hurdlers have performed well as an overall group. Before moving away from this section, both non-handicaps and handicaps have offered positive hurdling returns. Non-handicappers have returned 16p in the £, handicappers 9p.

 

Performance by Industry SP

A look at the results in terms of SP prices now.

 

 

There have been only small losses for shorter priced runners (5/2 or shorter). One can surmise that with a little bit of additional form study one could probably have narrowed down this group of runners in terms of which ones to back, with the potential to edge into profit as a result.

At the other end of the spectrum, horses priced 28/1 or bigger would have secured a very big profit if backing them all to Betfair SP. This will come as no surprise based on the information shared to date in this article about some big prices having gone in. While I am sure many of you are writing off the idea of backing such big-priced runners due to the fact that for such a method to work you probably need let’s say those monster 100/1+ winners hitting the mark more than they statistically should; or at least the prices of most of the winners offering value. However, the point is that one or both of the above has happened.

If we compare the results of horses priced 28/1+ in terms of British runners versus Irish runners, we see that British horses have won less than 1% of the time (0.97%) and produced losses of 56p in the £ to SP, and losses of 20p in the £ to BSP. Irish-trained runners priced 28/1+, as the figures in the table show, have won over 1.7 times more often than their British counterparts and the returns have been better by 39p and 63p in the £ respectively.

Of course, it takes a brave person with a large betting bank playing to small stakes to back very big odds runners regularly. Huge losing runs undermine confidence and if the tank is not set up appropriately, it could easily run dry. However, I found that this has not been a one-off after checking the record of Irish runners priced 28/1 or bigger from an earlier time frame (2008 to 2014). I haven’t gone back further in time because 2008 was the first full year that the Betfair Starting Price was used. Overall, during these seven years the bigger priced Irish raiders won 1.51% of the time (17 wins from 1127) for a profit to BSP of £725.31 (ROI +64.4%). Excellent overall returns once again – hence I am wondering whether anyone might be tempted to back such runners in the future. I, for one, will be keeping tabs on it.

 

Performance by Race Class

I want now to assess the class of race and whether it makes any difference either positively or negatively with regards to Irish performance in UK NH racing. Let me share the Betfair SP Return on Investment percentages (ROI%):

 

 

The chart has the highest classes of race on the left, starting with Class 1 races, moving through to the lowest class of race on the right, namely Class 6. It seems the better the class of race the more profitable for backers of Irish runners. Put simply, the highest three classes have produced profits, the lowest three losses. The BSP results for the two lowest Classes (5 and 6) have produced significant losses and it looks best to avoid these races.

If we look into Class 1 races in more depth, we see that Irish runners in all three types of Graded race (1, 2 and 3) have made a profit.

 

 

Don’t be put off by the low Grade 3 win strike rate as these contests, all handicaps, have averaged 20 runners per race over the past ten years. The class / graded data suggests to me that the Irish target the better races with higher prize money. That makes sense given the travelling costs and so on.

Before moving on I want to compare these Graded results to the record of British-trained runners during this period. Firstly, let me compare the strike rates, both win and each way:

 

 

Irish runners are ahead in all six comparisons and significantly so in Grade 1 and 2 contests. Now let me compare their A/E indices:

 

Again, the Irish runners have been completely dominant over their British counterparts offering better value across the board.

 

Performance by trainer

Trainer data is always popular so I will share the results for all Irish trainers who have sent 100+ runners to contest UK National Hunt races during this time frame, as long as they had at least one runner in 2024. The table is ordered by win strike rate.

 

 

The big guns of Willie Mullins and Gordon Elliott have sent a significant number of runners across the pond with good success. However, making a profit from either is not so easy due to their reputations; rheir runners do not go unbacked very often.

A few trainers in the list have shown a profit to BSP, but Gavin Cromwell and John McConnell’s results are the most impressive as they have not had a huge BSP winner to skew their results. Here are some additional stats for these two starting with Cromwell:

1. Cromwell has sent 36 runners to the Cheltenham Festival during the study period, of which six won (SR 16.7%) for a profit to SP of £20.63 (ROI +57.3%). This increases if backing to BSP to the tune of £36.20 (ROI +100.5%)

2. Sticking with Cheltenham, Cromwell's record at all other meetings at the course stands at 10 wins from 45 (SR 22.2%). Profits to SP have been £7.60 (ROI +16.9%), to BSP £11.36 (ROI +25.2%)

3. LTO winners from the stable have fared exceptionally well thanks to a 25% strike rate (16 wins from 64). Returns to SP were nearly 66p in the £, to BSP this increases to over 90p

4. Horses that started in the top two of the betting won 33 times from 105 runners (SR 31.4%) for a profit to SP of £8.74 (ROI +8.3%); to BSP £15.34 (ROI +14.6%)

 

Now onto McConnell:

1. Horses that finished in the first three LTO have been worth following thanks to 50 wins from 167 runners (SR 29.9%) for an SP profit of £23.22 (ROI +13.9%). To BSP this improves to £46.15 (ROI +27.6%)

2. McConnell's male runners have won almost twice as often as his female runners (26.6% versus 13.7%)

3. Horses that started favourite made a small SP profit of £8.16 (ROI +10.2%) thanks to a strike rate of 52.5% (42 wins from 80). Returns to BSP have edged up to just over 14p in the £

4. Hexham has been a good course for McConnell with 11 wins from 22 (SR 50%). He is only one win from 24 at the Cheltenham Festival, but at all other Cheltenham meetings combined he has saddled 10 winners from 44 (SR 22.7%) for an SP profit to £26.88 (ROI +61.1%); to BSP +£43.06 (ROI +97.9%)

-------------------

I hope this article has offered up some potential betting angles on Irish runners. It is widely known how well Irish runners perform at the Cheltenham Festival, but they also have competed extremely well at Aintree. In fact, Irish-trained horses' performance at Aintree is arguably more impressive than it has been at Cheltenham.

Bigger priced runners sent from Ireland to UK should not be totally written off as far more have won than statistically they should. Graded events have seen the Irish enjoy a clear advantage over British-trained runners, while the lower classes of 5 and 6 are generally races to avoid from an Irish perspective. There are two trainers that are worth keeping a particular eye on, namely John McConnell and Gavin Cromwell.

We have all heard the saying ‘the luck of the Irish’ but I think in UK NH racing terms there is a good bit more to it than that.
