Sir Allen

His career began with a first win at The Curragh back in October 2021, one of Irish racing's most famous venues, and he has been competitive ever since. His latest win came at Navan just this week, on 30 March 2026 — meaning he has won 2 of his last 6 races, which is a sharp return for any horse at this level and a sign that the Thurles yard has him in excellent shape heading into spring.

That yard belongs to trainer Andrew Slattery, who also takes the reins as Sir Allen's regular jockey — an unusual dual role that creates a tight partnership between horse and handler. Together they have teamed up 15 times, producing 2 wins, a success rate of around 1 in every 7 or 8 races. That might sound modest, but the fact Slattery keeps choosing to ride him personally says something about how much he trusts the horse in the right race. Slattery's operation is clearly firing on all cylinders this season, having sent out 57 winners — a number that marks this as a busy, ambitious yard well worth following.

Where Sir Allen really catches the eye is over a mile and one or two furlongs. In three races at that trip, he has won once — a 33% win rate, or 1 in 3 — and that kind of conversion at a specific distance is genuinely telling. Most horses take far more attempts to win at that rate. It suggests there is a very specific version of Sir Allen — over that particular trip, on the right day — that is hard to beat. With a career that has earned him five wins and still counting, and a trainer who clearly knows exactly when to aim him, Sir Allen looks like a horse with more to give yet.
