I have a few GRPs out on breeding
WSP Tiamat (stallion) and WSP Karisha (mare) are both competing in Pony Show Jumping. Both hold PSJ State Champion titles, and both are second/third gen ponies. In Pony Show Jumping I also have a British Riding Pony mare (can be bred with GRPs), PCRA Ciara. She's a foundation pony, but she holds PSJ International Champion title.
I also have a stallion pony in Dressage, PCRA Xavery. He holds a Local Champion title, and he's a foundation pony.
