I have a multi gaited standardbred, some might know.
I started trotting him a while ago, and in the start his trot was good, difficult to get, but once he started to trot he rushed away in ''racer trot'' a short while and soon started to listen to me and I could slow him down by posting slower, to a degree where he trotted almost at the spot, and resting on his steps. A very good trot according to my instructor :)
But now, it's easier to get the trot, but in the meanwhile the trot is worse.. :/ When I try to slow him down and get under himself, he sometimes goes back into gait (flatwalk-ish or a pace at some times) and he's more eager to just throw his head up and run for it.. while before he kept listening to me and stayed in trot once he got it.
I don't want to get rid of his gaiting, he's mainly a trilhorse, I just ride dressage (''academic riding'' for one of Bent Branderups students) to keep him soft, healthy and strong. Because I enjoy it too, but I want the gait for the trails and to work with along with the trot.
I get him to trot by posting and ''kicking'' with my inside leg while going on a circle. We started to try getting it from a leg yield or shoulder in but that didn't work at first. Now I can get a trot from a egyield on the trails or so. He was only allowed to gait for a year at first and just lately ''learnt'' to trot. When he rushes away I keep contact on the outside rein, make sure my outside leg is keeping a constant pressure on his shoulder (or else it ''runs away'' out) while tapping my inside leg and move the inside rein a little to get him to bend and soften, and give to the bit. It's what have worked before. I'm moving on a circle, btw. And I try to post a little slower than he trots, it's what he used to listen to the most. If I try to sit, it usually leads to him gaiting again as if he takes that as a cue that I want his back to stop moving so much.. :3
But I feel this is getting less and less effective, maybe he's just having a few bad weeks, but maybe you have some advice? :)
