Sounds like you might be lacking a little core strength in your erector spinae. Since you are jogging for a long distance, usually your torso is anteriorly tilted the entire time, so it's straining some of your intrinsic core muscles.
Look up a few exercises. They might be called different names depending on the source, but two great exercises are: the prone iso-ab & the two-leg floor bridge
As someone else said, Yoga helps immensely for core stabilization training.
