The headline achievement is hard to argue with: three top-level wins, two of them at Royal Ascot in consecutive summers. Ascot in June and July is the most competitive racing in Britain, the kind of stage where the best yards in the country show up with their finest horses. Winning there once is a landmark moment. Winning there in back-to-back years signals something more deliberate — that this team knows how to prepare a horse for the biggest occasion and get the result. The third Class 1 victory, at Lingfield Park in November 2021, came in only their first few months as a partnership, which tells you they hit the ground running from the very start.
The numbers this season tell a solid, workmanlike story. Twenty-one winners from 192 runners works out to roughly 1 in every 9 races — an 11% win rate that, across nearly 200 runners, means the yard is operating at a consistent, reliable level. Where things get more interesting is on normal ground, where the figures jump to 9 wins from 49 races, or roughly 1 in every 5. That is nearly double their overall average and worth noting if you ever see one of their horses declared on a dry, standard track. Newbury is another thread worth pulling: 3 winners from 15 runners at that particular track suggests a familiarity with the place that goes beyond coincidence.
Their go-to jockey is Lewis Edmunds, who has partnered their horses to 16 wins from 131 rides together — wins roughly 1 in every 8 times he climbs aboard for them. That kind of volume and consistency across more than 130 races speaks to a genuine working relationship, the sort where the communication between trainer and jockey is tight enough to make a real difference. Four years in, 106 winners, and two Ascot scalps already banked — Muir and Grassick are building something that looks like it has a long way still to run.
