Well, since you don't know all her background-they may very well have spun her before they took off. That's what my friend does before he goes out the gate, or even practicing in the outdoor-spins until his horse gets tense (others just do it once or twice) and then he takes off as soon as he feels that. He has to train his barrel pony to circle tighter and stay calm though, since a younger girl is riding him for 4H now.
I'd say that could be a very plausible reason, nonetheless.
Her old owners may have raced her with other horses in their fields or such too, we dothat with our horses too if we're all up for it. :3 it's pretty fun, but we have to make absolutly sure they're calm before and after. My friend's lease horse for 4H is a hyper mess the whole time, so he's usually not allowed to run him, but he ends up doing it in the end anyway ;-;
Another horse at the barn is/was a barrel horse. His leasee would hop on and either run him from a standstill or spin him and take off. He's well near ruined as a possibility of a sell prospect (as BO might have to sell all her horses pretty soon...) since his brakes are almost shot (needs a one-rein if he passes a trot) and he tries to take off at any leg pressure, lean forward, mount, etc etc.
But anywho...i would either just work on calm circles/spins, or attempt to find out what the previous owners did with her. :3 well, actually I'd work on circles/spins either way, haha, but yeah... Posted via Mobile Device
