Hi there! I've had similar problems with a lot of OTTBs. Have you tried any work with ground poles? I start mine with poles, making them canter some, trot some, walk some, canter in the pole line & trot out, etc. just lots of transitions over the single poles. You can also set up pole courses, and do transitions throughout the courses, make sure you mix up the pole courses & transitions to keep your horse on his toes & entertained so he doesn't get bored & run. When you feel your horse tense up/start to take off, circle out of the pole/jump and continue to circle until they relax, when he has relaxed then he can go over. Make sure you are also staying relaxed and breathing because if you tense up, then your horse will tense up & be scared too! You could also try halting in front of the fence, but don't over do it because it could teach him to stop at the fence. Another idea is putting either trot rails, or a rail a stride out before the fence, so that he has to bring himself back. You might also try gymnastics, such as a trot rails to a bounce to a bounce to a short one stride, so that he can't just flat out run, he has to bring himself back & collect, it might take a few times for him to catch on. If he does run at the fence, make sure you give him a short crest release, so that he is not getting rewarded for running. I had one TB that was an absolute terror to ride, until I tried lowering my hands, and that was the magic trick, they are a pretty qwuirky breed, so maybe your breaking one of his "rules." You could also possibly try a stronger bit, maybe a slow twist. TBs really do teach you how to ride. Good luck!
