Eek! I have my first jumping lesson since forever next week, and I'm terrified now. How the $^#$ did your horses get over those jumps? That must've been scary.
Meh, no worries! It was entirely rider error.
Horses jump blindly. They cannot see the fence when they are about 1, 2 strides away because it is completely out of their line of vision. So they rely 100% on their riders solidity.
So, when a horse takes a big spot, that is rider error. The rider either someway told their horse, "Ok now" through their bodies position - either dropping their shoulders, their heads, jumping ahead, etc, etc - which is what I did, I dropped my shoulders and gave him the signal "ok now"
I'm more annoyed at myself for permitting it to happen, instead of staying tall, solid and supportive to the fence, I stopped riding and he said "ok Mom".
It is a learning lesson for the rider, that's for sure!
