As one leg moves backward, it provides an equal and opposite force for the other foot to move forward.
No acceleration takes place. Runners are always at a fixed velocity.
The striking foot pushes backward against the ground. The friction with the ground provides an equal and opposite force forward.
The runner's upper body quickly leans forward, causing the entire body to begin accelerating forward
