Just curious... What is the optimal height for the horse to jump 3+? What about the weight of the rider (does it depend much as in races)?
I'm thinking about trying to jump mine year from now (when she'll turn at least 4). She cleared 4.5' fence just because (was overexcited because of the windy weather and new place) on slow speed uphill when she was 2.5 and 14'3'' in height , so I'm thinking may be there is some potential for jumping there.
I did just little jumping, so don't have much experience with it especially starting youngster.
