What shows can i train my 2 year old quarter horse pony for?

is there any shows i could train my pony for? some sort of event, or game show would be neat, and she loves to learn and do things, she is very smart and eager to learn, and she is more patient then i have ever known a young horse to be. she was at a rescue with a lot of other horses and didnt get a whole lot of attention so i thought this would be a good way for her to have fun and bond more with my and my sis, its her horse lol. any ideas? hope to hear back soon, your friend, trish
