Constitution River

Trained by A P O'Brien at Cashel in County Tipperary, Constitution River made his debut on the track at Galway on 28 July 2025 and broke his maiden straight away. He enjoyed a strong finish to that season, including a victory in the Futurity at the Curragh — one of the top races for young horses. A mishap during the off-season forced him to miss time, but he returned to racing recently and has barely put a foot wrong since. His most recent win came at Sandown Park on 4 July 2026, and though that was seven weeks ago, he remains an active contender with clear options ahead.

What marks Constitution River out is the quality of the operation behind him. O'Brien's yard has sent out 125 winners this season alone, a formidable win rate. The jockey Ryan Moore, one of the finest riders in Europe, has been full of praise. After one outing, Moore noted that Constitution River won with such ease he looked capable of stepping up in distance whenever asked. There is genuine talk of him following the route to the French Derby — one of the most prestigious races in Europe. The team has discussed multiple scenarios and options, and there is a clear sense that Constitution River is a colt with genuine potential and room to improve. At this early stage of his career, he looks like the real deal.
