That might help. The horse is 17hh. Size has never really been an issue for me, and as I'm tall I usually ride the larger horses. In fact, I usually like riding big horses, usually they're uncomplicated and there's a lot to get your leg round if they do bolt. But that seems like a good idea. I might phone them and ask if I can ride a 14.3hh mare that I like for my next lesson. Thank you.
