Endurance Running Hypothesis

Obviously I'm very intrigued by the Endurance Running Hypothesis as it's apparently referred to. As a long distance trail runner, I like the idea that humans have adapted themselves to be long distance runners. When people look at you strangely upon hearing that you run long distance races on trails, you can feel satisfied knowing that you're only doing what the human body was so beautifully designed to do. Whether you believe our bodies evolved this way or were created this way, it's nice to know that we are all born to run.

Here are some more interesting articles about the Endurance Running Hypothesis:
