Kat has this tendency to take over the last three strides to a jump, and I have a tendency to let her. I spend a lot of time retraining horses - it's part of my profession. So I have this fear of refusals, as in, I will make it over this jump no matter what happens.
It turns out that this is not precisely the way good performance is built, or something.
Anyhow, we've been working on the effectiveness of our half-halts before fences as recommended by RB. If she takes over and ignores the half-halt, bring her to a full halt whether or not her nose touches the jump. (This makes me cringe because I really feel I'm training a horse to refuse.)
However, I've only had to really shut it down a few times and our jumping continues to improve. She is on a very light rein in the canter as long as she maintains the tempo I set, and leg/rein as necessary to regain the tempo. The tempo is to remain the same before and after fences. (I've taught this lesson, I swear I have...)
The result is that I'm consistently picking our distances rather than Kat choosing. I'm learning from the photos that I ask for her to stand off the fence quite a lot. I also need to improve my release a bit, I'm entirely unhappy with the waffle-y nature it seems to have in the above photos.
Always more to learn, right?
Except for Kat. She has nothing to learn. She's perfect, I mean, look at her!
