Intrigued, I got some info from wikihow.
> If you are a fast runner or have bad knees, run in a straight line away from the attacker towards cover. The faster you can get away, the fewer shots they will be able to fire.
>If you are a slower runner and do not have knee trouble, a zig-zag run may be a better option. You may still be hit in this case, but the chances of being hit in a vital area may be reduced.
