Mark Rimell

Across his short career, Rimell has now trained 39 winners in total. For a trainer only four years into the job, that is a steady accumulation rather than a spectacular one, but the trajectory matters more than the total at this stage. The fact that his win rate has climbed so noticeably in a single season points to a trainer who is learning — better horses, smarter placement, or simply greater experience of knowing when a horse is ready to run.

His most productive alliance at the moment is with jockey Jack Mitchell, who has ridden 15 times for the yard and converted 3 of those into wins — a win rate of 20%, or 1 in every 5 rides. That is comfortably better than Rimell's overall average, which tells you something about the value of a settled partnership. When a jockey gets to know a trainer's horses well enough, the communication sharpens and the results tend to follow. Whether Mitchell becomes a long-term fixture in the operation remains to be seen, but right now that combination is one worth noting.

Four years in, 39 winners, and a win rate that is visibly improving — Rimell is building something rather than simply maintaining it. The next test will be whether the upward curve continues or levels off, as it does for many small yards once the initial momentum fades. But on current evidence, there is enough here to suggest this is a name that will appear more frequently as the seasons go on.
