Sir Callisto

Both of Sir Callisto's career wins have come at the same track, and he has managed them in just 6 attempts there — a 33% win rate, meaning he wins roughly 1 in every 3 times he lines up at Dundalk. For context, most racehorses are happy to win 1 in 10 anywhere, let alone at a specific venue. Some horses simply click with a particular place — the surface, the track's shape, the way races tend to unfold there — and Dundalk appears to be that place for Sir Callisto. His first win came there in February 2025, and his most recent followed in April 2026. He is not a horse who stumbled onto a lucky result; he has reproduced it.

He also has a clear preference for normal ground conditions, where his record stands at 2 wins from 6 races — that same striking 1-in-3 ratio. This is worth knowing because it tells you when he is at his best, and it overlaps neatly with his Dundalk form, suggesting the combination of the right track and the right ground is where this horse genuinely thrives.

Sir Callisto is trained by A.J. Martin, whose yard at Summerhill in County Meath has sent out 15 winners this season — a team clearly in decent form. His recent run of results reads 10-2-1-3-6-5 going back from his latest race, which was just yesterday. That sequence includes a win and a second, showing there is still live form here. He is not a horse for the highest-profile occasions, but he has carved out a genuine niche — and at Dundalk, on normal ground, he demands to be taken seriously.
