IT takes a special mare to produce two Group 1 winners, and although there are many who have achieved that feat, and even quite a few who have done it with their first two foals, the connections and fans of You’resothrilling have every right to be excited and to dream of what might come.

Her first foal won the Group 1 Irish 1000 Guineas last year, her second won the Group 1 Qipco 2000 Guineas at Newmarket last Saturday, and as each of her next three foals is a full-sibling to those stars, there is the potential that she could move up the list in the coming years, perhaps joining the select group who have had three Group 1-winning offspring.

Whether or not she can become one of those exceptionally rare mares that comes up with four individual Group 1 stars, or one of the handful that has given us five, is a big ask, of any mare, but her perfect start at stud leaves all possibilities open.

As with some who go on to be celebrated on the track, there are some fillies who go on to fame at stud despite coming from somewhat humble origins. One could certainly not say that about You’resothrilling.

Indeed, one could say that she had star potential from the moment she was born, and although she was ‘only’ a juvenile Group 2 and Group 3 winner during a short racing career, she was among the most exciting prospects when retiring to the paddocks and, given her connections, a rather obvious choice for Galileo’s book.

She is owned by the You’resothrilling Syndicate and her racing-age progeny are trained by Aidan O’Brien, carrying some of the famous Coolmore colours.

The fact that her third foal, a two-year-old, has been named Coolmore raises speculation as to how much potential that filly is showing at home.

Marvellous is her first-born and she won a mile maiden at Navan on her only start at two. She was unplaced behind Bracelet in the Group 3 Leopardstown 1000 Guineas Trial Stakes first time out at three but followed that with a three-length score in the Irish 1000 Guineas.

Being a daughter of Galileo and of a full-sister to an eight to 10-furlong champion, the Oaks and Irish Oaks were obvious targets. There was a chance she would stay, although no guarantee, and it appears that the trip was just a bit too far.

You’resothrilling is out of the US Grade 2-winner Mariah’s Storm (by Rahy) and her famous full-brother is Giant’s Causeway (by Storm Cat), the prolific Group 1 star who won the Juddmonte International Stakes, the Irish Champion Stakes and the Coral-Eclipse Stakes, in addition to being a dual classic-placed Group 1 winner over a mile and an unbeaten seven-furlong Group 1 scorer as a juvenile.

Giant’s Causeway, now 18, is a senior member of the team at Ashford Stud in Kentucky, a multiple champion US sire who has a long list of top-level winners to his name including the dual classic winner and excellent Kildangan Stud stallion Shamardal.

His best progeny are typically suited to around eight to 10 furlongs, although some stay further and those include the Group 1 Gold Cup winner Rite Of Passage.

That might sound as though Marvellous and her younger brother Gleneagles would surely stay beyond 10 furlongs, given Galileo’s phenomenal record, but their dam was a six-furlong juvenile pattern winner who was well-beaten the one time that she tried beyond a mile, and her siblings also include the Group 2-placed sprinter Freud whose stud success has largely come as being a source of speed horses.

If she had inherited the speed influences of her family, rather than the ability to stay 10 furlongs and beyond, then that always made it likely that her progeny might also have that cap on their stamina, especially when by a stallion who has had some stars suited by no more than that eight to 10 furlong range.

That is not to say that You’resothrilling will not come up with a horse who could excel at 12 furlongs, but merely a brief explanation of why the odds of that happening are slightly longer than some might expected.

It is worth noting that Giant’s Causeway and Freud are not her only full-brothers at stud.

Tumblebrutus won a six-furlong Naas maiden a month before filling the runner-up spot in the Group 2 Futurity Stakes over seven at the Curragh, and although he was well-beaten on his only attempts beyond that trip, his progeny in Chile include a Grade 1 scorer over 12 furlongs, and another who was runner-up in the Grade 1 El Derby over the same trip, along with various others who have done well in the broad six to 10 furlong range.

Tiger Dance, who was also trained at Ballydoyle, won his maiden over seven furlongs at Leopardstown and although well-beaten on every subsequent outing picked up Group 3-placing when a tailed off last of three in a seven-furlong contest at the Curragh as a four-year-old.

His offspring include a classic-placed South African 12 furlong pattern scorer among a variety of blacktype runners.

As you would expect of any regally-related son of Galileo, last week’s classic scorer Gleneagles is entered in the Investec Derby and in the Dubai Duty Free Irish Derby, but he is also in the Tattersalls Irish 2000 Guineas, in the St James’s Palace Stakes and in the Coral-Eclipse, and post-race comments by O’Brien noted the colt’s potential as a miler.

He was impressive on Saturday, all of his two-year-old form was over seven furlongs, and although an attempt at the Derby distance may be on the cards, this colt could instead be one of the year’s brightest stars in the eight to 10 furlong range.

Eventually he will, of course, take up his place at stud, and as a son of Galileo and of a pattern winning full-sister to Giant’s Causeway, a Group 1 winning juvenile who became a classic hero at three, and whose full-sister also succeeded at that elite level, Gleneagles will be one of the most exciting new recruits to the breeding shed.
