MOSTAHDAF, the joint-second best racehorse in the world, will retire to Beech House Stud in Newmarket after a final start in the Longines Breeders’ Cup Turf today.

He will be joined at the newly refurbished Beech House by the rest of Shadwell’s British-based stallions, including Baaeed, who are moving from The Nunnery Stud in Norfolk.

Mostahdaf’s 2023 season is headlined by triumphs in two of Europe’s premier races, coming from behind to win the Prince of Wales’s Stakes by an emphatic four lengths and making all to win the Juddmonte International Stakes by a length.

The son of Frankel became the first horse in 15 years to win both contests in the same season.

Trained by John and Thady Gosden, Mostahdaf won 10 of his 16 starts including eight stakes races to date, earning £2,345,277 in prize money. He holds an official rating of 128 and a Timeform rating of 129, making him one of the elite talents in world racing.

A Shadwell homebred, Mostahdaf is from a exceptional family of leading milers and sprinters. By champion sire Frankel, out of Dubawi mare Handassa, herself a stakes victor over a mile, Mostahdaf is a half-brother to dual Group 1 winning miler Nazeef, whilst his pedigree also contains two Group 1 winning sprinters, Pastoral Pursuits and Goodricke.

Stephen Collins, Shadwell’s European bloodstock manager, said: “Shadwell are delighted that Mostahdaf will retire to the newly refurbished Beech House stallion complex in Newmarket. He has all the attributes to become a successful stallion.”

The horse’s joint-trainer John Gosden commented: “Mostahdaf has always been a pleasure to train. Sound and always positive and generous in his work. His action is superb and fluent with a high cruising speed and electric acceleration. A horse who has been very consistent throughout his career.”

Nunnery Stud will remain the private base for the foaling of all of Shadwell’s mares visiting British-based stallions.

A fee for Mostahdaf will be announced shortly.
