Dirt vs. Turf v1.0
Identify prospects suited to dirt or turf racing.
Surface preference is considered to be indicated by pedigree and physical type since sires are often ranked according to the success of their progeny on different surfaces. However, it is often unclear until a horse has raced a number of times as to which surface it is best suited to. Similarly, some stallions can produce progeny with different surface preferences, in which case pedigree does not always indicate surface preference type.
Dirt vs. Turf v1.0 indicates the genetic affinity of an individual for achieving their best win on dirt or turf surface.
In the USA, 68% of Group races are run on dirt and 32% are run on turf, while in Europe, the majority (98%) of Group races are run on turf. This test, developed using horses raced in North America, analyses over 48,000 genetic markers to determine the result.
Horses are categorised as:
- Turf Pro – 80% suited to turf racing
- Turf – 50% suited to turf racing
- Dirt – 64% suited to dirt racing
- Dirt Pro – 75% suited to dirt racing
In a study of 273 retired racehorses from two leading US stud farms
- Horses with a ‘Dirt Pro’ result were 6.7x more likely to have won/placed on only dirt than turf.
- Horses with a ‘Turf Pro’ result were 2x more likely to have won/placed on only turf than dirt.
- The smaller amount of turf races available probably means that more turf horses raced on dirt due to lack of opportunity.
