Loop running animation for game

I’m fairly sure this is the right spot for this post, but forgive me if it’s not.

I’m making a simple(ish) game in blender, and I need to make my character run. I don’t want him to go from rest position to a jog, though, so I made him sort of push off from the ground at the beginning. Unfortunately, this makes him incorporate the push off every time the animation loops. Is there any way to loop it past the beginning?
(First Time: frames 1-60; Second Time: frames 15-60)
I know scripting basics, but I don’t know how to script for animations (or even if you can)
Anyone know how to do this?
