Willie Mullins Sends Minella Cocooner to the Grand National – Is He a Live Contender?
With a name like Minella Cocooner, you might expect a horse who’s still warming up, but there’s nothing sleepy about this one.
Trained by the unstoppable Willie Mullins, Cocooner is set to make his Grand National debut in 2025, and there’s a growing feeling that he might just be ready to burst out of the shadows and into the spotlight.
While he may not be the first name on every punter’s list, Mullins doesn’t send horses to Aintree for a day out.
Minella Cocooner has the stamina, the grit, and just enough mystery about him to make things interesting.
Could he be the latest in a long line of surprise packages to rattle the National pecking order? Don’t be too quick to write him off.
Quick Career Overview

Willie Mullins looks set to saddle six horses into the race, including last year’s winner I Am Maximus.
Among his team is Minella Cocooner, a horse that has quietly built a reputation as a capable stayer with untapped potential.
But can he defy the odds and emerge victorious at Aintree?
The horse has shown flashes of brilliance throughout his career, earning over £290,000 for connections.
While his form has been inconsistent at times, he has demonstrated an affinity for staying distances and challenging conditions.
That includes his 2024 Bet365 Gold Cup victory when he announced himself as a serious stayer by winning this prestigious 3m4½f handicap chase at Sandown.
He also placed third in the 2024 Irish Grand National, finishing just four lengths behind Intense Raffles in this tough 3m5f contest at Fairyhouse.
How It’s Going This Season
Minella Cocooner’s early-season form left much to be desired as he struggled in high-caliber Grade 1 races against elite opposition like Galopin Des Champs and Fact To File.
However, these runs were arguably prep races designed to sharpen him for handicaps rather than contests he was expected to win.
His performance in the Bobbyjo Chase marked a turning point. While finishing behind stablemate Nick Rockett, Minella Cocooner stayed on strongly over 3m2f on soft ground, a promising sign for Aintree’s marathon trip.
If the aim all along was to send Cocooner to Aintree, Mullins would have been carefully building his seasonal campaign around the Grand National and knows that he is capable of a good run.
Why Minella Cocooner Deserves Attention
Minella Cocooner thrives over extended trips. His performances in the Bet365 Gold Cup and Irish Grand National confirm his ability to see out long distances under tough conditions.
One of his standout attributes is his reliable jumping. He has never fallen, unseated, or pulled up in his career, which is a huge advantage in the Grand National, where navigating 30 fences cleanly often determines success.
Willie Mullins is fresh off a breakthrough Grand National win with I Am Maximus in 2024 and brings unparalleled expertise to this year’s race.
While his overall strike rate in the National is modest (13% placed finishers since 2000), Mullins’ meticulous preparation and tactical acumen cannot be underestimated.
Carrying just 11st 2lb, Minella Cocooner is attractively weighted compared to some of his more fancied rivals like I Am Maximus (11st 12lb) and Nick Rockett (11st 8lb). This could prove decisive on Aintree’s energy-sapping terrain.
He Still Faces Challenges
Undoubtedly, there’s a bit of inconsistent form going on with Minella Cocooner. His performances this season have been erratic, with heavy defeats in Grade 1 company raising questions about whether he retains his best ability.
The Grand National features a deep lineup including leading contenders like Stumptown and Intense Raffles, so like it or not, Minella Cocooner will need to deliver a career-best effort to prevail.
Mullins’ Six Strong Team for 2025

Mullins’ squad for this year’s renewal includes:
I Am Maximus: The reigning champion returns but must carry top weight of 11st 12lb.
Appreciate It: A Grade 1 winner but unproven over extreme distances.
Grangeclare West: Lightly raced but talented.
Nick Rockett: An improving stayer who won the Bobbyjo Chase.
Meetingofthewaters: A solid contender with experience in big fields.
Minella Cocooner: The dark horse with proven stamina credentials.
Each horse brings unique strengths to the table, but Minella Cocooner stands out as an intriguing outsider with untapped potential.
He Could Do It
Minella Cocooner may not be among the short-priced favourites for the 2025 Grand National, but he ticks many boxes for success in this iconic race: stamina, jumping ability, and an astute trainer who knows how to prepare horses for big occasions.
While his inconsistent form tempers expectations, his upward trajectory late last season, culminating in victory at Sandown, suggests he could spring a surprise if everything falls into place.
At odds of around 25/1, Minella Cocooner represents excellent value as an each-way contender.
Whether or not he can emulate stablemate I Am Maximus’ heroics from last year remains uncertain, but one thing is clear: this is a horse worth keeping an eye on come Saturday afternoon at Aintree.
