But the Duchess of Cambridge is one member of the Queen's family who doesn't consider herself a regular racegoer.

Kate, 39, didn't grow up with the traditional country pastime, nor has she expressed a natural interest in horse racing. She's also said to be allergic to horses, which explains why the mother-of-three is hardly ever spotted in the stands.

Back in 2009, Australian author Kathy Lette said she spoke to Kate during a polo match where Kate was cheering on her then-boyfriend Prince William. When Kathy asked the royal girlfriend why didn't play herself, Kate admitted: "I'm allergic to horses."

Marcia Moody, author of Kate: A Biography, has also previously told Town & Country: "Kate doesn't ride, purely because she didn't do it growing up. William and Harry were taught from an early age, but the only time they ride now is for polo – they don't go off on hacks like the Queen always has."
