During the ride, I felt that I really needed to step up my leadership. One the ground, I didn't really have the right tools to do a great job so once he seemed rideable again, I'd hop on and show leadership by moving his feet where I wanted them. We did transitions, isolating the ends, sideways... and I tried to make things quick and abrupt to interrupt the pattern of him thinking he needed to save himself. It was effective for the most part, but tiring and I got off once or twice just to take a break.
I rode him off and on, but multiple times it just seemed that he was so unconnected to me that he could get us in trouble so I'd hop off. About 1/2 mile from home, I got on and stayed on. He was calm close to home and I was not worried about riding him home.
Bottom line: he and I have some work to do on our relationship and his confidence. We'll keep going. I'd like to start riding him more alone. I just want to be sure I can do that safely.
