How would you explain to the general public the inner workings of the human body when walking? It sounds like an impossible task because the majority of the general public does not have the background in human biology to understand the integration of the skeletal, muscular, nervous, and circulatory systems needed to simply walk. Sam Schramski decided he was up to the task, and honestly, I thought he did a fantastic job. Drawing on his personal experience as well as the experiences of a professional runner, this article appears more everyday and less technical; however, Schramski does use some technical knowledge to engage more audiences. Schramski’s use of visual imagery and pictures makes every thing he writes come to life. As I was reading it, I could see him running part of the Appalachian Trail and birds making strides on “treadmills.” The hardest part to visualize was the Spring-Mass model. Maybe another image between paragraphs would have been helpful for readers that do not have an advanced understanding of physiology. My biggest complaint about the article is the links between paragraphs where the images should be. Twice, I accidently clinked on the links and was taken to a different page interrupting my reading of the article. One would think that such a simple action as walking would completely understood in our day in age; however, so much information is processed subconsciously while running, that it has proven extremely difficult to analyze what information the brain processes to adjust to new terrain. Even if Scott Jurek can run without watching where his feet will be placed, his brain is interpreting the visual information it is receiving and adjusting his legs accordingly. Jurek may think he is running blindly; however, his brain sees what he does not. In essence, his brain becomes his eyes and he thinks his way through the Appalachian Trail.
