What Does CD Mean in Horse Racing?

If you've ever looked at racecards and seen a horse marked with a “CD”, you might have wondered what those letters mean and whether they matter when choosing which horse to back. Here at Racing TV, we will examine what CD means, its impact on horse racing betting, and whether you should back a horse based on this information.

CD is something that signifies that the horse has won over the course and distances before, with the C standing for ‘course’ and the D standing for ‘distance’. If you see a CD labelled next to a horse, that means that this specific horse has won at this course over the exact distance before.

In the world of horse racing, small details can make a big difference, and CD is one of those details worth paying attention to. A horse that’s already proven over the same course and distance is often one to watch, especially if everything else aligns.

Next time you’re studying the racecard and spot a CD winner, give that horse a second look as it just might repeat history. When making use of horse racing free bets like those featured at Racing TV, the Course Distance indicator may be worth looking out for. However, take this with a pinch of salt, as horse racing is incredibly unpredictable, meaning no matter how many times the horse has won before, it might not this time.
