I just bought an OTTB mare, I've broke lots of horses. I ride western mostly, but I jump and I'm hoping to turn this mare into a jumper. She hasn't raced in years and I'm not really sure what to expect. Anyone have any advice on retraining? I've started probably 50 colts (I just turned 22) but they were all young and had nothing done with them, so there were no problems to undo. I have a small round pen and big open spaces to work in. We have lots of things to spook a horse here too, deer everywhere you look. Moose and bear too, and to get down the driveway of the farm my horses are at you have to ride past fields of buffalo. They stampede and go loudly crashing into the trees every time you ride by, sounds like an earthquake. My horses are used to it now but I'm thinking my first ride past them on an OTTB could be interesting. I have several thoroughbreds now, but they are not off the track, so I know how thoroughbreds can be, but am not familiar with racehorses. I've been told OTTBs usually have a bolting problem and usually don't like the feel of your legs. I've also been told you can't slow them down with the bridle, and if she thinks she's supposed to be running full tilt probably leaning back and trying to stop her with me seat would be useless. I took equine science in college and was told that the faster a horses legs are moving the slower it's brain is working!
