There's actually a fundamental difference between walking and running. When you walk one foot is always on the ground. When you run both feet are off the ground simultaneously during each stride.

The roll of the foot is the other big one. Humans are alive today because of our ability to walk, not to run.

It takes 3 days for a human to outrun a horse.
