I've had several attempt to run off. Pulling their head around and spurring the heck out of the off side - I mean lift your leg and hit with the spur, then do it again for as long as it takes to get their attention. Funny, that spur seems to get their attention when nothing else will. We have a mare that is as sweet as can be, but she was used as a pack horse most of her life before we bought her. She's a dream to ride . . .. unless another horse suddenly takes off. Past training kicks in and she thinks she needs to hurry up and catch up to the other horse. We were on a cattle drive one day up on the mountain not long after we bought her. We were in an open area when one of the teen girls who had ridden all of her life suddenly took off after a cow that quit the herd. The cow was running through deadfall in a thick aspen forest. The teen didn't seem to have a problem with running full tilt through that forest, but I did. If I hadn't had spurs on and hadn't started kicking with that spur as hard as I could at the same time I pulled the horse around, we would have been running through that forest trying to catch the other horse. She's not so bad at it now, as we don't use her to pack, and I've spent quite a bit of time ground training and riding her.
With all of our horses, lots of ground work and lots of hours in the saddle have made them pretty dependable. I've also found that working with a colt to by circling whenever it steps out of the gait you want it to use helps bunches if that colt ever decides to spook and run off. They are used to circling and seem to pay more attention to it when you ask/demand it of them under extreme circumstances.
I'll take a runaway horse any day over one that rears. Haven't had that problem with any of our horses, but I've seen it in others. There's little that's more dangerous than a rearing horse.
