We have taken the decision to retire Ms Parfois following a tendon injury to her near fore.
It is the latest blow for the yard during a frustrating season, when a combination of the virus and unseasonably quick ground over the winter have restricted opportunities for our horses.
A fortnight ago we had such high hopes that Ms Parfois would run a big race in the Grand National at Aintree, following her brilliant run when she finished second in the Midlands Grand National.
But she was then held up with a poisoned foot and once that cleared up she showed signs of straining a tendon.
Although we feared the worst a week ago we felt we had to give the leg a chance to settle down. But the strain is still there and at this stage of her life it made sense to retire her, rather than give her a year off and then bring her back into training.
Ms Parfois has been a brilliant flagbearer for the yard and her owner Martyn Chapman.
Given that she is now rated 153 over fences we will be extremely lucky to unearth another mare as good as her.
As Ms Parfois was at her best on testing ground we were already looking ahead to the Coral Welsh National at Chepstow in Xmas week.
But now her future lies at stud, with Martyn currently negotiating to sell her privately so that she can be covered in the next month.
