I consider myself a rider, not a trainer, so for me, the goal was learning to ride a horse that already knew the movements, not trying to teach us both at the same time since I had no idea what those movements were supposed to feel like. (I brought a horse to scores at First, but couldn’t get the hang of Second.) I would rather own the horse I show, so I bought a PSG schoolmaster, and got my bronze in two years (the first year was figuring out how to ride him!) and my silver the year after that.
A trainer I was riding with at the time still didn’t have her PSG scores yet (the horse she had retired, she couldn’t afford another, and we don’t have many FEI riders or horses in our area), so I let her show mine, and she got both scores in one weekend. It wasn’t a paid lease, I just let her ride him a couple of times a week for a few weeks, then show him, basically just as a thank you for helping get me there, and to help boost her business since she could now claim the Silver medal.
Now I have a GP schoolmaster (trained in GP movements, but hasn’t shown at that level), and am hoping to go for gold. We got the I1 scores in our first two rides. But GP is hard, and it’s going to take awhile to get it showable! (I’ve had him 3 years, and we’ve had some setbacks.) I do like that neither of us have shown the level, so it makes it a little sweeter if we can get there. I still admit that I could never train a horse to that level, but will be happy if I can ride it.
