If a horse constantly runs away, it's not only the behavior that has to be corrected, it's also getting down to the reason WHY the horse is avoiding his handler. Yes, it might be purely a habit. But it might as well be pain, ill fitting tack, the training methods, objectively too much work, unresolved fear issues, etc., etc. A horse has to have a motivation to be caught and, if there is none or if there are only unpleasant experiences after being caught, is he really to be blamed?
For example, I used to know somebody whose horse constantly would run away from her in the pastures and be very hard to catch. When she finally would catch him, she'd bring him over to the barn, lunge him HARD for about an hour in mostly fast trot and canter, whip for disobedience, then ride him with his head constantly cranked in and then lock him up in the barn without hay for several hours "as a punishment for running away". No wonder the horse was soon completely impossible to catch... Of course, this is an extremely negative example, but it shows how the horse is trying to tell what's wrong with this kind of behavior.
I have come a long way, to surrender my shadow to the shadow of my horse.
