Cross country is all about trust. If your lease horse jumps fine when you’re not scared then that shows that you trust him and he trusts you. When it is scary he has to make sure that you are not pointing him at something that could hurt him, and when the scary jumps are coming, you have to trust him to carry you safely. You have to trust him not to hurt you and show him that you have confidence in him. Pretend that he’s just a baby and he’s scared and you have to let him know that it’s going to be okay. Cross country is supposed to be fun!! Just relax, put some trust in your horse, and know that he’s going to take care of you since he has before.
