Last year's Arkle heroine Put The Kettle On beat the boys again in the Betway Queen Mother Champion Chase at Cheltenham.
A surprise winner at the Festival 12 months ago, Henry de Bromhead’s mare had stretched her unbeaten record at the track to three on her first start of the current campaign in November.
But despite her excellent record in the Cotswolds, she looked to have her work cut out on her return, having proved no match for Chacun Pour Soi at Leopardstown over Christmas.
Put The Kettle On was in front for much of the contest, but looked booked for minor honours after odds-on favourite Chacun Pour Soi hit the front approaching the final fence.
However, Aidan Coleman’s mount fought back on the run-in – devouring the hill once again to get up and score by half a length as a 17-2 shot, becoming the first mare to win the two-mile showpiece.
Dan Skelton’s Nube Negra finished strongly to claim the runner-up spot from the Willie Mullins-trained Chacun Pour Soi.
Coleman said: "I jumped off to get a good start and wasn't really sure where I’d sit as this was her biggest test, and I didn’t know if she’d be quick enough to be bang there.
"She was very good over the first three or four fences, and after I’d jumped four I was fairly confident that I’d stay there until at least turning in and then what will be will be.
"I had the partner with the attitude and ability. It’s fantastic.
"I don’t know what is about Cheltenham with her as this is the only place I’ve ridden her. As long as she can come here a couple of times a year and do the business we’re happy enough!
"If I could bottle what she has I wouldn’t have to ride again – I’d sell it, and be a rich man."
The Waterford trainer said: "She’s an incredible mare, I’m delighted for the owners, it’s just brilliant, the stuff you dream about.
"She’s so tough and Aidan was brilliant on her. He really asked her at the last three and that probably won him the race.
"I don’t know what it is about this place. A couple of weeks ago she just wasn’t herself, but we freshened her up as much as we could and she seemed much better. When she arrived her she was what we expected. She’s a bit mad actually.
"I have to congratulate everyone at home, but especially Andrea who looks after her and puts up with her antics every day, it’s special for her. She’s quite wild at home, she’s a great character.
"Mid-February I was probably leaning towards running in the Mares’ Chase, but we all discussed it and I looked at the stats for the previous year’s Arkle winner in this and they are ridiculous so we said we’d give it a lash and see.
"Winning the Champion Hurdle and Champion Chase with mares especially, it’s the stuff of dreams. I’m just delighted."
Mullins said of the Paul Townend-ridden Chacun Pour Soi: "Paul's feedback was that he ran a bit flat, which looked obvious. I’ve not seen any other reason to say that is not right. It’s disappointing. He had every chance to win the race but he didn’t.
"Usually in the middle of a race Paul gets a feel for him that he has plenty in the tank but he didn’t get that feel at all today. He thought he was flat from early on. I don’t know why he was like that.
"Paul more or less said before they turned up the hill that he knew he wasn’t going as well as he does at home or giving him the feel at home so I’m not sure I’m taking the hill as a big problem for him.
"It was him on the day that was the problem not the hill. Chacun Pour Soi was beaten by a course specialist so maybe he was just beaten by a better horse on the day."
