Movie Monday: Why we run

Here's a short video on Bernd Heinrich, an ultramarathoner and biologist who lives in the woods of western Maine.  Heinrich is also the author of the 2002 book "Why We Run," in which he blends the science of running with his own anecdotes of a life spent on the trail.

I will never get tired of videos like this that manage to capture the beauty and simplicity of running.  Enjoy.
