I just had my first experience with a runaway horse yesterday and it might just keep me from ever getting on another horse again. I've only owned him for a week and a half but the people i bought him from are reputable ranchers / horse people. He's a six-year-old quarter horse gelding (somewhat speed bred) and he's been used as a sale barn horse and a ranch horse, covering thousands of acres. I rode him through the round pen, the corrals and out in the pasture and back in again and he was fine. The second time we went out in the pasture he just flat took off on me. I've never been on a horse this fast and he was absolutely out of control. I had the reins in my hands and the more I pulled and tried to stop him the harder he ran. I finally got his head cranked around to the left and that's when I went off the left side - not sure if I jumped off, fell off, or was thrown off from the momentum - it all happened so fast. The whole deal lasted a good 30 seconds, maybe even longer. He even ran me right through three other horses in the pasture. He's never been a spooky horse so I don't think that was the problem. I can't figure out what would have spooked him anyway. Has anyone else had a problem like this, especially with a six-year-old that has supposedly never done it before? I'm starting to question any horse now and I'm not sure I'll have the nerve to get on anything again. Thanks for any advice!
