In the Prometheus School of Running Away From Things, they teach you to throw your human logic out the window, and instead follow the example of Prometheus for a better movie moment. First use stand there and watch the thing draw closer. Once you’re in actual imminent danger, run just slightly faster than whatever is chasing you. Run in a straight line directly in the path of the object, and allow it to get very close to you, but don’t get hit. Undergo the chase for as long as possible, then jump out of the way at the last possible second.
