William Dewhirst

There's a horse who genuinely loves one place above all others, and that place is Newcastle. William Dewhirst has raced there 14 times and won on 6 of those occasions — that's winning nearly 1 in every 2 visits to the track, which is a remarkable record by any standard. For context, most good horses win roughly 1 in 5 or 6 races across their career. To nearly halve that at a single venue suggests something real: a combination of the track's layout, the surface, or simply a horse that settles and performs when it gets back somewhere familiar.Based on TrackLab's AI analysis

Across his career, this 6-year-old has won 8 from 29 races — a win rate of 28%, or roughly 1 in every 3.5 races. That's a genuinely healthy record at the level he competes, which is typically the fourth tier of British racing: competitive enough that winning is never easy, but not quite the rarefied air of the top prizes. His 14 placed finishes alongside those 8 wins also tell you he's consistent — he shows up, and he rarely finishes at the back.

His most important partnership is with jockey Paul Mulrennan, who has ridden him 17 times and won on 6 of those occasions — a win rate of 35%, or just over 1 in 3. That kind of chemistry between horse and rider matters. Mulrennan clearly understands how William Dewhirst wants to be ridden, and the numbers back it up. Ben Haslam trains him from Middleham Moor in North Yorkshire, a yard that has sent out 35 winners already this season — a busy, functioning operation that knows what it's doing.

The honest part of the picture, though, is that his recent form reads 9-7-9-7-2-3 — finishing in the top three twice from his last six races but not winning any of them. His last victory came at Newcastle in February 2025, now 15 months ago. That's a drought for a horse who has shown he can win, and the finishing positions of 9th and 7th scattered through those recent runs suggest he hasn't always been competitive. He raced just yesterday, so he's very much active and being kept busy by the yard.

Whether the winning form returns will likely depend on getting back to Newcastle, getting back alongside Mulrennan, and finding the right race. All three things are within reach. The ingredients are there — they just haven't quite come together lately.
