The day-to-day numbers tell a similarly solid story. Over the last twelve months, the yard has sent out 206 runners and turned 20 of them into winners — that works out at roughly 1 in every 10, a 10% win rate that reflects a professional, competitive operation rather than one throwing horses at races and hoping for the best. Their standout jockey partnership is with Lewis Edmunds, who has ridden for them 143 times and converted 15 of those into wins, also at 1 in every 10. That kind of long-running, consistent relationship between trainer and jockey matters — it means the horse arrives at the track with a rider who genuinely understands how the yard likes to operate.
One particularly interesting pattern is how the team performs on normal ground conditions. When the track is riding as expected — not wet, not firm, just standard — their win rate climbs to 16%, or 9 wins from 57 races. That is noticeably better than their overall average, suggesting they are especially good at identifying horses and picking races for days when conditions are straightforward rather than extreme. It is the kind of detail that rewards anyone paying close attention.
Four years, 108 winners, and three top-level victories — including at Ascot — is a track record that would take most yards a decade to build. Muir and Grassick are doing it at pace, and the evidence suggests they are only getting started.
