Dual Champion Chase winner Moscow Flyer has died aged 22, the Irish National Stud has announced.

Trained by Jessica Harrington during his racing days, Moscow Flyer won 26 of 44 starts including 10 Grade One events over fences and three wins at the highest level over hurdles.

Moscow Flyer bowed out of racing action after finishing fifth in the 2006 Champion Chase at Cheltenham — a race he won in 2003 and 2005 — and spent the latter half of his retirement at the Irish National Stud, in County Kildare.

A statement on www.irishnationalstude.ie read: “It is with great sadness that the Irish National Stud must announce the passing of the legendary Moscow Flyer at the great age of 22.”

Harrington said Moscow Flyer had been suffering with colic.

The County Kildare handler added that he was a “horse of lifetime”, and nominated his victory in the 2004 Tingle Creek at Sandown over old rivals Azertyuiop and Well Chief as her particular highlight.

She said: “He’d been in great form at the National Stud. He wasn’t doing the shows any more, he gave that up three or four years ago.

“People forget how good a hurdler he was. He was winning Grade Ones around the time of Istabraq. He was very smart but completely different over fences.

“Without a shadow of doubt, I think the day he was at his best was Sandown in the Tingle Creek.

“That day it all went like clockwork against two other brilliant horses.

“After that, I’d say regaining his Champion Chase (2005) was his best day.

“He was the horse of a lifetime. I’ll never have another like him, I know that.”
