Galileo Breaks World Record in G1 Irish Thousand Guineas

Tara Madgwick - Saturday June 13

Galileo filly Peaceful ran out a dominant winner of the Group I Thousand Guineas (1m) at The Curragh overnight making her sire Galileo the most successful sire of Group I winners in history.

Trained by Aidan O’Brien and ridden by Seamie Heffernan, Peaceful powered clear of two more Coolmore entries in Fancy Blue (Deep Impact) and So Wonderful (War Front) to win by two lengths.


“Peaceful is a lovely filly, she always was and was always very high class. She was working lovely coming into the race,” sad Aidan O’Brien.

“When Love did what she did at Newmarket we were always looking forward to today. She's very uncomplicated and Seamie gave her a very straightforward ride. We'll see how she is but she could go to the Coronation Stakes. We think she'll get further.”

A homebred for Coolmore, Peaceful was placed once in a Listed race last year and this was her second win from just four starts.

She is a full sister to stakes-winner Easter and is the best of four winners from stakes-winning Stravinsky mare Missvinski.


Coolmore’s legendary sire Galileo is now the most prolific source of Group I winners in thoroughbred history, with 85 of his sons and daughters now having won at least one race at the top level. 

Now aged 22, he has been crowned champion sire in Britain and Ireland in 11 of the last 12 years, and wrested the leading sire of Group I winners title from his former studmate Danehill. 

The pair had remained tied on 84 top-level winners apiece since Galileo's well travelled daughter Magic Wand landed the VRC Mackinnon Stakes at Flemington in Australia on November 9 last year.

She was also successful on the Curragh program winning the Group II Lanwades Stud Stakes at her first run in Ireland this year having been second in the Pegasus World Cup Invitational back in January and then ninth in the inaugural Saudi Cup.

Galileo shuttled to Australia for his first five seasons

Galileo shuttled to Australia for five seasons at the start of his stud career between 2002 and 2006, and left five Group I winners from those five Southern Hemisphere bred crops in Linton, Niwot and Sousa, while Igugu and Mahbooba won their Group I races in South Africa.
