Have you ever wondered if you can run without getting caught by the principal? Well this is exactly what you are looking for. Instead of holding whatever is your run key spam it. If you don't know what I mean, it's basically when you press your run key a lot of times while walking giving you a boost without getting caught. Pressing something a lot of times really fast is counted as spamming. The principal classifies running then walking running then walking running then walking as not running.
