Joseph Patrick O'Brien's yard at Owning Hill has clearly spotted something special. O'Brien noted before her breakthrough that the filly had exciting pedigree and arrived with genuine class, though she was just touched off by a high-class rival on her reappearance. That debut taught her nothing harsh — she won her first race at Navan on 25 April, and the jockey Joey Sheridan's recollection tells you something important: he rode confidently, knowing he had a classy horse beneath him, even when it got tight. The early wins came at around 1m3f to 1m4f, distances where she has won two of three races, suggesting this is her sweet spot.
What makes her genuinely interesting now is the trajectory. She's not a flash in the pan. Her recent form reads 1-4-1-1-2-2 — which means she's been consistent, mixing wins with narrow defeats, never far away. She raced just yesterday and is still active, so the yard clearly views her as a horse worth running regularly. With a yard sending out 160 winners this season alone, O'Brien knows how to prepare horses properly, and the fact that Thundering On keeps turning up and winning or placing suggests she's being handled exactly right. At three years old, she still has most of her racing ahead of her.
