Jackrabbits are fast, they can really run, except sometime when they overbreed and start to starve, then they don't move very fast.

I read that the female can get pregnant while she is pregnant, so she has fertilized eggs ready to drop into her uterus when she gives birth. So conditions being right, she is always pregnant, but hunger in the fall and winter keeps her from going into season.

Nature was cruel to the female hare. Pregnant or hungry all the time?
