The catalogue for the Inglis Ready to Race October 2021 is now available. Ready to race sales have advantages over conventional yearling sales. The horses are broken in, fit to race and prospective buyers can see the horse’s action from their breeze up videos. There is also a record of the time they are capable of running. You will probably pay more dollars for this information. The advantage of seeing a horse run should not be underestimated. Those who have been following my posts will know that I selected fourteen yearlings during the 2019-2020 sales period. These horses are now 3yo. Of the fourteen, all have been named, but only 6 have started in a race.  Of these, three have won and another placed. For the other eight, their 2yo career is over. Dreams of a Golden Slipper triumph evaporated. Of the one hundred and eighty-five 2yo on offer at the Inglis Ready to Race Sale I have looked for fast horses with PRI back up.

Dosage and Fast Horses

The Dosage system attempts to put a numerical analysis on the pedigree of a horse which is based on its Speed and Stamina. For those interested I would recommend Steve Roman’s book “Dosage Pedigree and Performance”. The data can be utilized in a number of ways. One choice is to establish a Dosage Index (DI) which is simply a measure of speed to stamina.  The Table shows the range of values for the DI for a number of races as well as for champion sprinters in Australia in the last ten years or so. The data can also be arranged to provide a value for Centre of Distribution (CD). This figure marks the balancing point of a pedigree between speed and stamina and it is displayed by a number between +2 and -2. A positive number shows speed outranks stamina and a negative number stamina out ranks speed. The Table below sets out some DI and CD values of relevance.

It is clear from the data that the range of values for speed horses, (2yo in the Golden Slipper and the Blue Diamond, and that of Champion Australian sprinters) show different dosage profiles from the horses that have won the Melbourne Cup and the UK St Leger.

Dosage Ratings of Horses at the Inglis Sale

I did not measure the DI and CD values of all the horses in the sale. I cut the list to those where there was a reasonable quantity of data available and selected three horses for comment. Lots 93.45 and 79 should have exceptional speed. In fact, lot 93 is more like a quarter horse. However, the low PRI score probably means it could run out of breath rather quickly. Lots 45 and 79 have strong PRI scores to back up their speed rating. It will be interesting to see how they go. Paper studies are useful but so is the real thing and to see that you need to look at the information provided at the Inglis Ready to Race Sale in October.
