Motion Paths- Creating a Consistent Speed

Hi everyone!

I am using a motion path within my current project that is set on a loop. I need it to maintain a consistent speed throughout the animation. I've noticed within the motion path that the animation wants to slow down towards the end. Is there a way to keep it from doing that? I've made sure that the duration of the motion path is consistent with the timeline, thinking it would fix the problem, but it still slows down towards the end of the path. 

Any suggestions?
