Nothing could be further from the truth so I think I should take the time to explain both what a good Thoroughbred cardio looks like, and why there are limitations to cardiovascular testing alone.

I actually misspelt his name when I was imaging him but you can take a look at his race record by clic

3 Lessons Learned about Genetic Testing of Thoroughbreds
