My horse is 14.3 hh and I hope to be jumping him quite high. I am training him myself and the highest we've jumped so far is just 21/2 feet but I hear pings can get to a quite high jumping standard. :) and my boy is a standardbred I rescued him from the race track :) Posted via Mobile Device
I use to jump a 13.3 mare. I was 5'8" I had to swing my legs back so they didn't knock the poles down.
She was one of the guttiest ponies ever, she could really fly but she was also a difficult hot ride and always in season during the summer! To slow her I had to sit deep and use my legs, she would pee, swish her tail but check back. To go, just sit and click!
My current eventer(gray) is 15hh flat, and overjumps 3ft in his sleep. He used to compete 3ft6 hunter jumpers, schooled 4ft easily. I just don't have the guts to go higher yet. My old pony(black) is almost 14.2hh and topped out at about 2ft9. She has very bad hips and that has since retired her from jumping anything more than 2ft. She was definitely capable of going higher when she was in her prime though, despite not learning to jump until she was about 12.
Bailey over 3ft.
