But if I saw an ad on Craigslist for a horse trained in Parelli, I'd skip to the next ad. Where I live, the image that comes to mind is of a horse that is poorly mannered and rarely ridden.
One of the ladies who really introduced me to Parelli for my problem horse, is an endurance rider, and is a solid Level 4 in the program! I too ride endurance, and she can ride circles around me! She was out there riding yesterday in the brutually cold wind. She rode on the paved road in front of her house because there is too much ice in the fields. She GPS tracks her miles, and she is conditioning one horse, and training 2 of her others. She will have two horses competing in endurance full time this season.
She has extremely well mannered horses (I trim their hooves!). Her horses can be pointed at a trailer parked 100 yards away, and they will run to it and jump on. She can canter her horse in a field with NO tack whatsoever, not even a halter. Her horses are worked, they are worked with, and they are ridden a LOT. A whole lot!
Yes, I do trim for some "Parelli people" who do not ride, and that have spoiled, rude horses. But I also trim horses for plenty of ordinary traditional people with the same kind of bad tempered horses.
I really don't think you can sum all the Parelli riders up in on lump. The ones I have met at the Horse and Soul tours, absolutely do ride! Many of them are at the stage of being able to jump and canter bareback with no tack. These are some seriously trained and accomplished horses.
My one Arab mare I have started over from scratch, starting at the very basic friendly game on the ground and going up from there. I am now riding her about 3x per week, and she is so connected to me at this point I can drop the reins on her neck and mostly just think about where I want to go or what I want to do, and she responds very nicely. This is a really hot, high spirited horse that was spooking at everything, getting herself spun up on adreanaline, and was extremely dominant. The change in this horse is absolutely remarkable.
I really don't believe you can group "Parelli people" in one lump any more than you can "dressage people" or "working cow people" or "western pleasure people." There are so many different types of riders within those groups, you are bound to see good, bad, and everything in between!
