What Does Group 1 Mean in Horse Racing?

The term “Group 1” in horse racing means that the race is of the highest level possible.

In some of these races, the horse needs to achieve an official rating of 115 to compete.

As the G1 is the highest grade of thoroughbred racing it attracts the most prize money and therefore the best horses in the world.

Horses will travel globally to compete in these competitive events. Many Group 1 races are held at festivals such as Royal Ascot, The Breeders Cup and the Dubai World Cup night.
