Charles Darwin

The headline result came at Royal Ascot on 19 June 2025, where he won a Class 1 race — one of the very best races in Britain, at the sport's most famous meeting. Winning at Ascot at any level takes something special. Winning a Class 1 there as a young horse announces you to the world. His trainer Aidan O'Brien, based in Cashel, Co Tipperary, described him afterwards as "a very fast, big, powerful, strong horse" with "a very good mind" — and noted that jockey Ryan Moore essentially let him find his own way once the gates opened, at which point he simply powered through the line.

O'Brien is one of the most successful trainers in the world, and his yard has already sent out 144 winners this season alone — a number that makes most training operations look modest by comparison. When a trainer of that calibre describes a horse as "very exciting" and a potential "very good sprinter," it is worth paying attention. The plan, he has said, is to bring Charles Darwin back to Royal Ascot for the Commonwealth Cup, a prestigious sprint for three-year-olds. That gives this current campaign a clear destination and a genuine sense of purpose.

What makes the profile even more intriguing is that Charles Darwin missed the second half of last season after winning three times, including the Norfolk Stakes at Ascot. He has come back this year and picked up exactly where he left off — most recently winning at Navan just this week. O'Brien has spoken about how the horse does everything easily, almost too easily, describing him as still "babyish" despite his size and power. A big, mature, physically imposing horse who still has room to grow into himself is a slightly alarming thought for whoever lines up against him at Ascot.
