Today, Jaz & I took about a half dozen steps at the canter.
Thanks to Heather for tilling the round pen, which always gives me a bit more confidence and sense of security when trying anything. I know now that my problem has been timing. I was thinking that canter had to be faster, and so I was getting into a really fast trot and asking for the transition, and Jaz wouldn't. Today, I asked for the canter from a slower, more fluid trot. I still have to convince him I'm serious, because we've just trotted for so long. I don't blame him for not believing me. Everything else must have also been right, because after I did it once, I was unable to duplicate it.
I'm whupped and super happy.
