Peaceful provided Aidan O'Brien with another Classic victory when running out an impressive winner of the Tattersalls Irish 1,000 Guineas at the Curragh.

On the back of Love dominating in the English equivalent at Newmarket last week, Peaceful was always in the perfect position under Seamie Heffernan.

She quickened up past Valeria Messalina well over a furlong out and never looked liked getting caught, beating Donnacha O'Brien's Fancy Blue with So Wonderful in third. The favourite Albigna was out of the frame.

The winner had only managed to win one of her three starts last year and was beaten a neck in Listed company at Newmarket on her final start.


However, Heffernan, who had earlier bagged a double on the card, had full confidence is his mount's ability to stay and she was subsequently cut in the market for the Investec Oaks at Epsom, with Betfair offering 11-2 from 14-1.

Fancy Blue made great late progress to give Donnacha O'Brien a great thrill so early in his training career, but Albigna never looked comfortable.

Peaceful's success provided another notable milestone for Coolmore stallion Galileo, with the filly giving the sire his 85th Group One win, setting a new record. 

Lancaster House resumed winning ways with an all-the-way success in the Coolmore Calyx Gladness Stakes.

Winner of his first three outings last year having been unraced at two, he could finish only seventh when losing his unbeaten record in the Boomerang Stakes when last seen.

Seamie Heffernan bounced him into an early advantage and while major market rival Speak In Colours appeared to be travelling better a furlong out, Lancaster House (6-4) found plenty for pressure to give Aidan O'Brien a first win in the race since Excelebration in 2012.

"I'm delighted" said O’Brien. "She’s very uncomplicated, handles fast ground. Seamus has been delighted with her all the time. He rides her in all her work. Everything has gone very smooth with her. 

"She will get further than a mile so a mile here on beautiful ground really suited her. It was a great ride, he was very confident she would get the trip well. 

"She could come back here to the Irish Oaks, she could go to the Coronation on Saturday. All the options are there. We’ll see how she comes out on Monday. She’s a lovely filly. 

"We’re so lucky that this is all happening here in Ireland, that John (Magnier) decided to base his family and everybody here. We’re so lucky with the stallions here, and the broodmare band here. 

"It’s a massive industry, a lot of people employed and a lot of people that it puts bread on the table for us all. 

"We’re just privileged to be a small part of it and be able to work with these horses." 

O'Brien and Heffernan had earlier been on the mark with Snow (5-1), who along with stablemate Salsa dominated the Irish Stallion Farms EBF Fillies Maiden, before prevailing by three-quarters of a length.

A sister to 2018 St Leger winner Kew Gardens, having shown a modicum of promise in two runs last season, not surprisingly she was suited by the step up to 10 furlongs.
