In 5* events the top riders are invited to participate, they don't pay!
They do it every weekend because most horses are not theirs, it's the owners that pay for travels and everything! Every time a horse goes to that shows it gains value, when they sell a horse, they receive a percentage, that's were they make money!
And of course if they win the classes!
Hope it helps
Maybe to travel all around the globe, to pay your coach and grooms and all the staff is enough.
But where does the money come from them? Cause they earning good money🤔
According to fei rules when you compete in a csi 5* you don’t have to pay an entry fee 😊 you do have to pay one for 1-4* shows
