Sheikh Ahmed’s daughter of Selkirk will forever hold a place in her trainer’s heart having provided him with a first Group 1 win in last season’s Prix de l’Opera at Longchamp on Arc Day.

Nahrain was unraced at two but soon made up for this at three, winning her maiden at Windsor before following up in a handicap at Haydock and also winning her first Stakes race in the Coral Distaff at Sandown in July.

Following a short lay-off she then showed tremendous tenacity to hold off Announce by the smallest of margins in the Prix de l’Opera when ridden by Frankie Dettori.

She then travelled to Churchill Downs where, despite losing her unbeaten record, she put up a gallant display to finish second to Perfect Shrill in the Breeders’ Cup Filly and Mare Turf.

As a four-year-old, Nahrain failed to sparkle on her first two starts of the year but signaled that she was returning to form when third to Up in the Blandford Stakes at the Curragh.

She then travelled to Belmont Park where under a masterful ride by John Velazquez she took the Grade 1 Flower Bowl Invitational, her second top-flight success.

Her final start came at this year’s Breeder’s Cup at Santa Anita where unfortunately she never got involved in what was a messy contest.

All in all she won five of her 10 racecourse starts, amassing prizemoney of close to £700,000.

Her departure will leave a void at Kremlin but the search goes on for another Group 1 performer to fill her shoes.

Roger said: “Nahrain left us yesterday and will not race on as a five-year-old. She has been a huge asset to the start of my training career, winning five of her 10 starts including two Group 1s.

“She has been a pleasure to train and I now hope she has a long and successful career as a broodmare.

“It is sad to see her go but she has given us some great days and we now have to work hard to find another one as good.”
