Yeah I don’t know what the very modern trends say but 10+ years ago plenty doubled up.
We’ve had alot of deep ground Cheltenham’s in recent years, maybe they take their toll when coming to Aintree if those trends have flipped….
Many ways to skin this cat, but decided to have a go over my morning cuppa today. I'm typing this as I go along so no idea where it will lead...
Let's start with the baseline level. Since 2008, any horse who ran at the festival LTO before going on to Aintree in any race.
1605 bets, 168 winners (10.47%), 461 places (28.7%): -257SP, +126.54BSP
Let's immediately switch that to Grade 1 or Grade 2 races only at Aintree - leaving Grade 3 out as that would include Grand National.
743 bets, 116 winners (15.61%), 289 places (38.9%): -130SP, -5BSP
Clearly got a better chance of winning a graded race having run at a graded race at Cheltenham. Let's look at the breakdown of won, placed (2nd or 3rd) and unplaced at Cheltenham.
WON: 90 bets, 30 winners (33.33%), 57 places (63.3%): -3SP, +4BSP
PLACED: 188 bets, 43 winners (22.87%), 98 places (52.13%): +10SP, +52BSP
UNPLACED: 465 bets, 43 winners (9.25%), 134 places (28.82%): -137SP, -61BSP
Interestingly, unplaced horses are about par for the course in terms of Aintree performance, but winners in particularly do have a great chance of following up over the whole time period. I'll focus on winners for the next part just because that was the initial conversation, but you could just as easily included placed horses for approx 28% strike rate and bigger "blind" profit. Anyway, quick breakdown by year - I'll split this into 3 groups for brevity. The Golden Years (2008-2014), The Pre-Covid Years (2015-2019), The Post-Covid Years (2020-2022, not including this year)
GOLDEN: 50 bets, 18 winners (36%), 34 places (68%): +9SP, +14BSP
PRE-COVID: 28 bets, 8 winners (28.6%), 15 places (53.6%): -15SP, -14BSP
POST-COVID:10 bets, 3 winners (30%), 7 places (70%): +4SP, +5BSP
I'm not sure what conclusion to draw on that. I'd say 30% of horses following up at Aintree is a fairly large percentage but others will have different views. It's worth noting that the average win odds were 2.89 (SP) and 3.21 (BSP) so 30% obviously isn't that great when compared to implied SP percentage chance of 34.6% chance of winning. Finally, does Cheltenham going affect the results?
HEAVY: 1 bet, 0 winners (0%), 0 places (0%): -1SP, -1BSP
SOFT: 13 bets, 3 winners (23.1%), 6 places (46.2%): -8SP, -8BSP
GD-SFT: 43 bets, 13 winners (30.2%), 27 places (62.8%): +2SP, +7BSP
GOOD: 33 bets, 14 winners (42.4%), 24 places (72.7%): +4SP, +11BSP
Ground at Cheltenham clearly an influencing factor for me rather than specific season. Should be noted that in the POST-COVID years when Cheltenham ground was defined as GD-SFT:
7 bets, 2 winners (28.6%), 5 places (71.4%): +5SP, +7BSP (i.e. all the profit)
What does it all mean? Horses follow up in Graded races at a decent strike rate from Cheltenham to Aintree, when the ground at Cheltenham was Good to Soft or better. The ground was soft on all four days at Cheltenham this year so we should be marking up any repeat winners. I've got to look at today's racing now so maybe I'll play about with stats from the placed horses another day. Could be a worthwhile set of stats for Fairyhouse Easter and Punchestown as well, but I'll see.
