It seems clear that some do, to the extent that the Official Handicapper rates something over two hundred horses separately on each, recognising their differential achievement. While being clear that horses' career records sometimes indicate an ability to be more successful on one than the other, I've never really understood why that should be, so posed the question on Google and got the following AI generated reply:
"Racehorses may prefer all-weather surfaces over turf because of physical soundness, stride biomechanics, and the predictability of the track. Grass courses vary wildly with the weather, but synthetics provide consistent footing, better shock absorption, and a firmer, springier surface that reduces fatigue for certain equine athletes.
Several specific factors explain why certain horses excel on synthetic or all-weather (AW) tracks:
This strikes me as a clear and convincing set of reasons and makes understandable the sense that one needs to be wary of horses whose record suggests a strong preference for the aw when running on turf. But only one of the three - "biomechanics" - seems potentially to help explain the reverse, why, apart from horses with a very clear preference for soft or heavy, some seem to prefer turf.

Several specific factors explain why certain horses excel on synthetic or all-weather (AW) tracks:
- Footing and Stride Timing: Some horses struggle to grip the turf, especially if it gets too wet or "heavy". All-weather surfaces (like Polytrack or Tapeta) offer a more uniform, predictable surface that allows these horses to maintain a consistent rhythm and stride.
- Shock Absorption: Synthetic tracks are engineered with silica sand, rubber, and wax. This mix provides excellent shock absorption, which is particularly beneficial for horses with joint or tendon issues.
- Biomechanics: Just like human runners, horses have different running styles. Horses that have a lower, "daisy-cutting" stride often glide more efficiently over the smooth surface of an AW track."
