🐴 Sun Racing Plate Handicap Chase Preview

Cheltenham (Old Course) | Tuesday 10 March 2026 | 4:40pm | 2m 4f 44y | Good to Soft | 23 runners | Prize: £84,405

Race Context & Likely Shape

Twenty-three go to post for the Sun Racing Plate over two and a half miles on the Old Course at Cheltenham — a maximum-field cavalry charge that traditionally produces one of the most baffling puzzles of the entire Festival. The ground is Good to Soft, which should suit the majority and place the emphasis squarely on class, jumping, and positioning rather than any surface bias.

The Old Course configuration is a factor that too many preview pieces gloss over. The tighter loop back from the far side of the course, the sharper bend into the home straight, and the shorter, more abrupt uphill run-in all reward horses who possess tactical speed and the capacity to quicken under pressure. This is not the New Course's more stamina-sapping slog to the line. The Plate on the Old Course is a race where a well-timed move entering the final two fences can steal the whole thing — but also one where an over-aggressive ride through the middle of the race can leave a horse legless on the hill. In a 23-runner handicap chase, expect the early tempo to be fierce, expect the cross-fences in the back straight to claim victims, and expect the winning horse to be the one that has navigated the chaos of the middle section with the most petrol left in the tank.

The weights span from Dee Capo's 12st 0lb at the ceiling (OR 154) down to Moon d'Orange and Yes Indeed on 10st 2lb at the basement (OR 128) — a 26lb spread across the handicap that tells you the compression here is severe. A handful of pounds in hand can be the difference between winning and finishing mid-division. The market is headed by joint-favourites Madara and McLaurey, both at 9/2, with Will The Wise next at 8/1, followed by Downmexicoway at 9/1 and Zurich at 11/1. Several major yards are triple-handed: Henry De Bromhead sends Downmexicoway, Zurich, and Theatre Native; Dan Skelton saddles Madara, Boombawn, and Riskintheground. Gordon Elliott runs Dee Capo and Down Memory Lane — with Jack Kennedy taking the ride on the latter, a jockey booking that always demands attention at the Festival. The Mullins family is represented by W P Mullins with O'Moore Park and Emmet Mullins with the joint-favourite McLaurey. Gavin Cromwell sends two in Will The Wise and Midnight It Is, and the Jonjo O'Neill yard has Peaky Boy and Jipcot. It is, in short, a race packed to the rafters with quality, ambition, and plotted moves.

Previous Festival form is gold dust in these contests, and the horse that arrives here having proved its wellbeing on recent starts — rather than one being nursed through the handicap on hope and reputation — tends to be the one that handles the unique pressures of a Cheltenham Tuesday.

🎙️ Philip Opens

"Afternoon all, and welcome to what I have long considered the Festival's answer to an existential crisis. The Plate: twenty-three runners, six or seven plausible winners, a market that looks like it was assembled by a committee that couldn't agree on what day it was, let alone which horse is best. There's a wonderful line from the philosopher Karl Popper about science progressing through conjecture and refutation — and frankly, the Plate is a race that refutes everyone's conjectures with gleeful regularity.

"Mick, you've been hunched over your phone since five o'clock this morning, scrolling through X and the form book like a man trying to crack the Enigma code. The market says Madara and McLaurey at 9/2 apiece. Is that your starting point, or have you already talked yourself past the favourites?"

🗂️ Mick — Case-Based Reasoning

"Philip, let me be upfront about this: if you're backing the favourite in the Plate, you haven't been paying attention. The base rate for market leaders in big-field Festival handicap chases is grim. So yeah, I'm looking past the 9/2 shots, and I'll tell you exactly why before I get to my picks.

"Madara at 9/2 — look, he's a professional runner-up. The form reads 842-52. Two seconds in his last three completed runs, never actually winning. Harry Skelton will give him a lovely ride, Dan Skelton's yard is motoring at 54% RTF, but this horse has a topspeed figure of just 129. In a race where runners like No Questions Asked and Zurich are clocking topspeed figures of 149 and 147 respectively, Madara simply doesn't possess the finishing gear to close out a race like this on the Old Course. He'll run his race, he'll finish somewhere between fourth and eighth, and his backers will say 'ran a blinder,' and I'll say 'yeah, he always does.'

"Then there's McLaurey at 9/2. Now I know Emmet Mullins has the highest RTF in the field at 67%, and I know Mark Walsh is an artist in the saddle, but mate, the form figures are 0-4374. That reads like a PIN code for a lost bank card, not the CV of a Festival favourite. The market is pricing in a training plot — the idea that Mullins has been sandbagging this horse through the handicap and it'll suddenly pop here. And fair enough, that does happen. But when I look at the actual evidence the horse has put on the racetrack, I can't back him at that price. Strong stable, wrong horse. Maybe.

"So my headline pick is Zurich at 11/1. This is a seven-year-old, by Doctor Dino — and Doctor Dino throws proper Cheltenham types, horses who handle the undulations, the ground, the whole package. His form reads 30-113: won his last two, progressing with every run. Brian Hayes rides, which is a quiet booking but an effective one — Hayes knows this horse inside out. He's on an OR of just 134, which means he carries only 10st 8lb, and in a race where the top weight is lugging 12st, that's a pound-for-pound advantage you can't manufacture. His topspeed figure of 147 is right near the top of the field. Now, my Fermi guesstimate on this — if you asked me to price Zurich's true ability as a handicap mark, I'd put it somewhere around 140 to 142. That means he's got approximately six to eight pounds in hand off this mark. Roughly right, Philip, roughly right. That's your edge in a race like this.

"For my each-way safety I'm going with Down Memory Lane at 12/1. Form figures 324-01 — he won last time out, and that's a clean, confident victory heading into the Festival. Trained by Gordon Elliott, whose yard is operating at 58% RTF, and ridden by Jack Kennedy. When Kennedy picks one horse from an Elliott team of two at the Festival, you sit up and take notice. He's chosen Down Memory Lane over Dee Capo, and Kennedy doesn't make that call lightly. He's eight years old, OR 152 so carrying 11st 12lb, which is a fair old weight, but the RPR of 157 and a topspeed of 139 tell you he's a genuine contender off that mark. The weight is a concern, I won't lie — but class can carry weight, and a Festival-primed Elliott horse with Kennedy up is not something I want to oppose.

"And my value swing — Jipcot at 18/1. Now this is one for the connoisseurs. Jonjo O'Neill's seven-year-old, form reading 0P-314. Those opening figures look ugly, but peel them back and they came in races at a much higher level. His last two runs — third and fourth — have produced topspeed figures of 146, which puts him right in the mix with the principals. He's down at OR 133, carrying just 10st 7lb with Kielan Woods aboard, and the price of 18/1 in a race where anything from 8/1 to 20/1 has a genuine chance is a fat number. If the early pace is as suicidal as I think it'll be, a horse who can pick up the pieces from off the pace at a light weight is precisely the type you want.

"As I always say — being approximately right is better than being precisely wrong, and in the Plate, you need conviction. These are my three and I'm sticking with them."

🎙️ Philip → Pearl Transition

"Thank you, Mick. So you're heavily invested in the De Bromhead angle through Zurich, the Elliott-Kennedy axis through Down Memory Lane, and a value dart at Jipcot from the O'Neill camp. Three different yards, three different form profiles, one common thread: you're betting against the favourites. Pearl, before you give us your own thinking, I want to probe something. Mick's approach is fundamentally pattern-based — he's extrapolating from De Bromhead's Festival handicap record and the Kennedy jockey booking as signals. But isn't there a confounding variable lurking in that logic? A stable's past success in a category doesn't tell you which of its current entries is the live runner. How do you untangle the stable effect from the individual horse effect?"

🔗 Pearl — Causal Analysis

"Philip, you've identified exactly the right question, and it's the classic confounder problem that bedevils pattern-based reasoning in racing. The stable reputation acts as a confounding variable because it's causally connected to both the selection decision and the outcome. Punters see 'De Bromhead in a Festival handicap' and assign a higher probability to all three runners, when in reality the stable effect is concentrated in the specific horse that's been prepared for the target. The other two entries may be making up the numbers. So the question is not 'is De Bromhead good at this?' — that's established — but rather 'which De Bromhead horse is the live one?' That requires horse-level analysis, not stable-level pattern-matching.

"Let me build the causal DAG for this race, because it clarifies the decision architecture enormously. In a 23-runner handicap on the Old Course, finishing position is mediated by three primary causal pathways. The first is in-running position — where the horse travels through the race directly mediates the relationship between its inherent ability and its result. On the Old Course, with those tighter turns and the sharper uphill finish, a horse that can sit in the first ten, travel without burning energy, and quicken when asked has a structural advantage over a closer who needs a long run-in. That's the mediator. The second pathway runs through weight: every pound a horse carries has a direct, measurable causal effect on its ability to sustain effort up the Cheltenham hill, and in a compressed handicap, small weight differences translate into large finishing position differences. That's the treatment variable. The third is what I'd call jump efficiency — in a race where the early tempo ensures fences come thick and fast, a horse's accuracy at its obstacles either enables or blocks its ability to convert talent into a finish. That's the collider: poor jumping blocks the causal pathway from ability to result, and in a 23-runner chase, one bad fence can end your race regardless of your talent.

"Now, applying this framework to the joint-favourites is revealing. Madara at 9/2 has form figures of 842-52, and the market reads that as consistency. But from a causal standpoint, those seconds tell you something different: they tell you that when the mediating variable of finishing effort is applied — the last half-mile, the final hill — Madara does not have the causal machinery to convert a good position into a win. His topspeed of 129 is the hard evidence. The consistency is real, but it's a ceiling masquerading as a floor. McLaurey at 9/2 is a different problem. The market is pricing in a latent variable — the expectation that Emmet Mullins has been deliberately shielding this horse's true form through the handicap. In Bayesian terms, the prior is strong: Mullins targets big races and his 67% RTF suggests his runners are trained to the minute. But the likelihood, given the observed evidence of 0-4374, is weak. Strong prior, weak likelihood — the posterior probability should sit somewhere in between, and I'd argue 9/2 is too short for a horse whose actual evidence on the track gives you very little to work with.

"So here are my selections. My headline pick is Downmexicoway at 9/1. This is the horse in the field with the clearest causal trajectory of improvement. If you strip out the P at the beginning of his form — which was a pull-up some time ago and doesn't reflect his current ability — the sequence reads 0, 1, 2, 1, 3. That is four top-three finishes from five starts. The critical counterfactual I always ask is this: if you ran this race a hundred times under a hundred different pace scenarios, how often does this horse finish in the first five? With Downmexicoway, I'd estimate sixty-five to seventy percent of the time. His consistency is not random — it's the product of identifiable causes: he's a seven-year-old at the peak of his development cycle, he's been progressively campaigned to arrive here at the right trajectory, and his rider Darragh O'Keeffe has been on board for the key recent runs, which eliminates the jockey-change confounder. At an OR of 145 he carries 11st 5lb, which is manageable, and the implied win probability at 9/1 is approximately 10%. I estimate his true win probability closer to 13 or 14%, which gives you a marginal but real edge. In a race this competitive, marginal edges are all you get.

"For my structural each-way play, I'm going with No Questions Asked at 14/1. This is where the speed figures become genuinely illuminating. His topspeed rating of 149 is among the highest in the field — only Midnight It Is and Grandeur d'Ame edge him out at 150, and neither has shown recent form to justify confidence. That is a significant data point on the Old Course, where the shorter run-in and abrupt finish reward precisely the kind of finishing kick that topspeed measures. His form of 0-1231 shows he's been competitive at a consistently high level, and Ben Pauling's yard is operating at 48% RTF. At 11st 9lb off an OR of 149, his weight is within the band where the ability-weight relationship remains positive. The market has him as sixth or seventh in the betting, but the speed evidence suggests he should be closer to third or fourth. At 14/1 each-way in a 23-runner race, the place terms alone make this structurally attractive.

"And I do find myself in agreement with Mick on Zurich at 11/1 as a progressive selection. The evidence of two sequential wins is more than pattern — it's a causal signal that suggests genuine upward trajectory. A single win can be variance; two consecutive wins against decent opposition, with improving speed figures, represents a sustained causal effect — improved training, improved confidence, improved jumping. At 10st 8lb he carries one of the lighter weights in the field, and the interaction between light weight and the Old Course's punishing hill finish is one of the strongest predictive relationships in Festival handicaps. My only caveat — and this is where I depart slightly from Mick's confidence — is that the base rate for 'progressive Irish handicapper winning at the Festival' includes a lot of false positives. The likelihood ratio isn't as generous as the raw form suggests. But at 11/1, the market compensates adequately for that uncertainty.

"As I often say: prediction is not explanation. I can build you a causal model for why these three should run well, but twenty-three runners generate twenty-three possible stories, and only one of them ends with the winner's enclosure."

🎙️ Philip Challenges Mick

"Mick, Pearl's made an important point about the confounder between stable reputation and individual horse probability. You're asking us to back Zurich essentially because De Bromhead does well in these races and the price is right. But she's also flagged that De Bromhead has three runners — Downmexicoway, Zurich, and Theatre Native — and the stable effect may not be equally distributed. How do you know Zurich is the live one and not just the one that's attracted the market's attention because of those back-to-back wins?"

🗂️ Mick — Rebuttal

"Fair challenge, and I'd be a mug to dismiss it. But here's where the case base fills in the gaps that the causal model can't. When I look at Zurich compared to De Bromhead's other two, the differentiator isn't just the wins — it's the profile of those wins. Zurich is improving with every run, and his last two victories were achieved with something in hand. That's the type that goes to a Festival handicap and finds more. Downmexicoway is consistent, and Pearl's right that his trajectory is strong, but he topped out at third last time. Theatre Native at 33/1 hasn't shown enough recently — form of 1-0396 doesn't scream 'Festival plot.'

"And here's something the causal framework misses: the jockey booking tells you something about connections' confidence. Brian Hayes rides Zurich, Darragh O'Keeffe rides Downmexicoway, Mike O'Connor rides Theatre Native. O'Connor is the conditional — that tells you Theatre Native is the third string. Hayes and O'Keeffe are both capable, but the fact that connections have split their best two jockeys across two live horses tells me both are genuine. That's why I'm backing Zurich and Pearl's backing Downmexicoway, and we might both be right. The De Bromhead stable effect could land in either lane.

"Plus — and I keep coming back to this — the market isn't stupid. The overnight money that's come for Zurich on Betfair, the weight-of-money pattern, tells you the sharp operators rate this horse. When my case base, the social media chatter, and the betting exchange all point the same way, I listen. That's not herd mentality, that's convergent evidence."

🎙️ Philip Challenges Pearl

"Pearl, your case for Downmexicoway at 9/1 rests heavily on that form trajectory — four top-three finishes from five starts. It's compelling. But here's my concern: his most recent run was a third, not a first or a second. If the trajectory is truly ascending, shouldn't the most recent data point be the strongest? A third last time out suggests either the trajectory has plateaued or the level of competition has increased beyond his capacity. At 9/1, you need him to better third place to profit on a win bet. Is the market already pricing in that trajectory, making 9/1 fair rather than value?"

🔗 Pearl — Rebuttal

"That's a legitimate Bayesian challenge and I want to address it precisely. The third last time does not necessarily represent a plateau — it can equally represent a data point drawn from a higher-quality distribution. In other words, if the race in which he finished third was stronger than the races in which he finished first and second, the third is actually a more impressive performance in absolute terms, even if the placing is lower. This is the base-rate trap: people anchor on finishing position without adjusting for race quality. The confounding variable is opposition strength, not the horse's own ability.

"But to your specific question about whether 9/1 is value or merely fair — I concede that the edge is marginal, not enormous. I'm not claiming Downmexicoway is a 5/1 chance being offered at 9/1. What I'm claiming is that his implied win probability of roughly 10% understates his true probability of approximately 13 to 14%, and that his each-way probability — top three or four — is where the real structural value lies. In a 23-runner handicap at the Festival, the most profitable bets are typically not the win singles on the favourite but the each-way plays on horses in the 8/1 to 16/1 range whose floor of performance guarantees they're in the conversation. Downmexicoway's floor is higher than any other horse in this race, and that's what you're really buying at 9/1.

"I'd also note that the interaction between his running style and the Old Course is a genuine causal advantage. He races in the pack, which on a tighter course with a shorter run-in gives him the positional edge to be in the right place when the race unfolds. Closers are disadvantaged on the Old Course; prominent travellers are advantaged. That interaction isn't priced into the market because the market doesn't formally model course-configuration effects."

🎙️ Philip's Summary

"Right then, let's weave these threads together before I embarrass myself with the Weekend Warrior.

"What strikes me most about this discussion is the convergence on the De Bromhead yard — Mick through Zurich at 11/1, Pearl through Downmexicoway at 9/1, and both acknowledging the other's pick as legitimate. That's two panelists, two reasoning frameworks, two different horses from the same stable, and a shared conviction that the De Bromhead handicap operation is the key force in this race. That level of structural agreement from fundamentally different analytical approaches is notable. Whether the stable effect lands through Zurich's progressive profile or Downmexicoway's consistency trajectory, the De Bromhead saddlecloth looks the one to follow.

"Equally notable is what neither panelist is backing: the joint-favourites. Madara at 9/2 is dismissed by Mick on speed evidence and by Pearl as a ceiling masquerading as a floor. McLaurey at 9/2 gets a more nuanced treatment — both respect the Emmet Mullins angle but cannot reconcile the form figures with the price. The market says these are the two most likely winners; the panel says the market is wrong. That's a bold position in a race where the wisdom of the crowd usually has something going for it, but both have articulated clear reasons for looking elsewhere.

"In the each-way zone, Mick has Down Memory Lane at 12/1 and Jipcot at 18/1; Pearl has No Questions Asked at 14/1 and shares Mick's enthusiasm for Zurich at 11/1. The common band here is the 11/1 to 18/1 range, which is where Festival handicap winners have historically clustered in this type of race.

"Consolidating the panel's work into my own summary staking plan: my win pick is Zurich at 11/1 — the convergence selection, backed by both pattern evidence and causal trajectory. My each-way play is Downmexicoway at 9/1 — Pearl's headline case is persuasive, and the consistency floor makes the place angle especially attractive at the prices. And my risk add is No Questions Asked at 14/1 — the topspeed figure of 149, among the highest in the field, is a compelling structural edge on the Old Course where finishing speed is rewarded.

"As the great Phil Bull wrote: the form book is a record of the past masquerading as a guide to the future. In the Plate, we all pretend we can read it. Twenty-three runners will remind us that certainty is a luxury we cannot afford."

🧢 Weekend Warrior — Philip's Live Longshot

"And now for the segment that exists purely so I can either torment my colleagues or be tormented by them. My Weekend Warrior selection is Guard Your Dreams at 28/1.

"Here's the narrative. He's ten years old, trained by Nigel and Willy Twiston-Davies with Sam Twiston-Davies in the saddle — this is a family operation, a horse they know inside out, aimed specifically at this race. The form reads 74F-21: a fall in the middle of the sequence, which the market has clearly anchored on. But strip out the F — and we have discussed at length on this panel that falls can be contextual rather than dispositional — and his last two completed runs are a second and a first. The RPR of 157 is competitive with anything in this field. He's on an OR of 141, carrying 11st 1lb, which is a workable weight. Sam Twiston-Davies knows the Old Course inside out and has the tactical nous to keep this horse out of trouble in the early exchanges before delivering a late challenge.

"He's not in the model, not in the memory bank, and the market has barely bothered to notice him. But the name alone — Guard Your Dreams — feels like a Festival horse. And if he frames a place, I shall be insufferable about it until at least Gold Cup day. Consider yourselves warned."
