I made the switch a number of years ago for similar reasons you are considering. My then-hunter/eq horse was getting older, had a “bad farrier experience” that resulted in some hoof challenges and needed an easier job. He was (is) a heart horse and I had always enjoyed flatwork so I thought it would be fun to explore dressage so we could still have goals and something to work toward.
Well, I never would have expected it, but OMG I fell in love with dressage - it is endlessly fascinating! And way, way more challenging / fun than I expected. My horse turned out to be quite suitable for lower level dressage and got me almost all the way to my bronze medal before I semi-retired him; I now have two other purpose-bred dressage horses that I am bringing along and I find I don’t miss H/J-land at all.
The transition was challenging - in a good way. It took awhile for me to lengthen my leg, and really SIT - something I still work on pretty much daily! But the connection, the subtlety of the aids and the improvement in my communication with my horses is absolutely and totally addictive. It’s been so much freaking FUN.
Dressage shows, IMO, are also way more fun - for a number of reasons. For one thing, there are RIDE TIMES. Yes, that’s correct! No more hurry up and wait!!! You know exactly when you are going to ride and it is FABULOUS.
Also, you get written comments from the judge for each test, so you know exactly, movement by movement, what went well and what did not. Also, since you get a score for each movement in each test, it is entirely possible to make even a pretty big mistake and still wind up with a good score and a nice ribbon! Unlike that feeling you get when you chip the first jump, or pull a rail… you are still in the game, so to speak, and can recover by putting the error behind you and continuing to ride the rest of the test to the best of your ability.
Our shows are generally also held over the weekend - no more having to take time off work because your class is scheduled on Wednesday. Well, I might ship over on a Friday afternoon to school. But the shows themselves are generally Saturday-Sunday. Yay! And BTW, dressage shows IME are sooooo much cheaper. I used to budget around $1500 per H/J land, and that was shipping myself. These days, I’d guess I spend a third of that! The braids are so quick and easy to do that a lot of people DIY. Lots and lots (most) people look after their own horses vs. having lots of grooms.
I have found the camaraderie at dressage shows is wonderful. Everyone is really riding against a standard, and trying to get the best score they can more than they are competing against the other folks in the class. There is lots of support and encouragement.
Oh, and there is BLING. I mean, not everyone is a fan, and that may or may not be something that interests you. But for me, the choice of gorgeous browbands, a little bit of sparkle from a fancy button on your show coat or what have you is also really fun.
Welcome to the bright side
