Running straight

I have a runner and character starts by jumping off the cliff to the running road. The thing is that after animation is finished character is always rotating in wrong direction so it falls off the road. (slight degree an it’s going bad).
What is the adjustment method of this problem? I tried offset of Y axis in animation but it does not help.
Question is how to run straight according to road and not to fall off while doing so?

Try to freeze the y rotation in your Rigidbody

Hey guys try to make vice versa. So ground is scrolling(not the player movement)
