Mine is the same way...even at a trot he wants to jump. I just sit back and do a couple of half halts prior to the first pole a few times. After a few tries he settles. Two poles three strides away..he still gets quick and will sort of hop over the second pole and land in a canter...two or three in a row at proper distance gets him pretty forward as well..we are working on it.
Talk to your horse, do a little half halt, turn away from the pole occasionally so the horse doesn't anticipate, or, as already indicated, just wait him out. :)
I find after a while a horse won't want to expend any more energy than they absolutely have to.
