I have an Anglo Arab, 15.3, with long legs and a
short back. Her gaits are smooth, but I had despaired of her ever picking
up a fast downhill walk, although after 2 solid years of riding, it is getting
faster.
Anyway, just recently (she is 6, going 7), she has
started to pace at the walk on downhill, especially steep ones. She
seems very balanced...and is just trucking fast along....but I have never, in my
life, seen a horse pace at the walk.
