READERS of this column will be aware of the existence of eight ‘Blue Hen’ mares, the only broodmares to have produced four or more individual Group or Grade 1 winners. This elite coterie could soon be increased in size, and the hot favourite to do so must be the Storm Cat (Storm Bird) mare You’resothrilling.

Gaining both of her juvenile victories in blacktype races, the Group 2 Irish Thoroughbred Marketing Cherry Hinton Stakes at Newmarket and the Group 3 Swordlestown Stud Naas Sprint Stakes, You’resothrilling joined her six-time Group 1 winner and champion sire full-brother Giant’s Causeway (Storm Cat) and became a second stakes winner for her dam Mariah’s Storm (Rahy).
