Outstanding Group I winning mare Prowess has run her last race with Kingsclere Stables announcing the daughter of Proisir has been retired due to a degenerative hoof condition.
"The whole team at Kingsclere and the ownership group are absolutely devastated to share the news that Prowess's racing career has been cut short," a tweet from Kingsclere Stables read.
"She is a once in a lifetime horse that gave us many thrills and changed many people's lives.
"Due to the degree of changes present in the left foot, the mare will require a period of specialist farriery treatment and rehabilitation.
"Once changes of laminitis have developed to this degree, it is very uncommon for horses to return to the stresses of racing."
A $230,000 Karaka Book 1 purchase from Hallmark Stud for her trainers Roger James and Robert Wellwood, Prowess won eight of 12 starts earning $1.5million and win the Group II MVRC Crystal Mile during a brief campaign in the spring.
The full sister to Prowess will be a highlight at Karaka Book 1 offered as Lot 21 by Hallmark Stud.
