This is all very good advice. My trainer has known this horse since she was 4 years old. She'll be 11 this Friday (Happy B-day Belmont). Anyway, she told me the other day that she remembers her doing the exact same thing when she was younger. Lately I have been doing a lot of halts with her. The second she starts to run off I stop her and then we go from walk to stop to trot to stop to walk, etc.I don't do it in front of the jumps though. My trainer and I have been working on stopping after certain jumps that she tends to run through. Lately I have been better about being able to keep my leverage and sit back in the saddle but occasionally she will catch me off guard and pull me out of the saddle and then my fight isn't only to get her stop, but for me to also get back in the position where I can lean back and pull up on the reins to get her to listen.
