Let's make this birthday one to remember.

55 years old (Born on October 16, 1969)

Happy Birthday, Aidan O'Brien! You're the only trainer we know who can rack up more frequent flyer miles than your horses. From Ireland to Canada, France to Italy, and across the pond to the U.S. and Great Britain—you've conquered them all with style. At this point, we're pretty sure even Pegasus would ask you for training tips.

Here's wishing you another year filled with thrilling finishes, record-breaking victories, and fewer early mornings (though we doubt that last one). May your birthday be as legendary as Galileo's offspring and as memorable as your countless Group 1 triumphs. Cheers!
