We talk a lot about our bodies. We talk about what hurts. We talk about what is not working as it should. We talk about the things we are doing to accommodate injuries or treatment for maladies. We are embodied beings. We relate to our world and all that is in it through our bodies. We know the world around us by what we see, hear, smell, and feel. Our life is dependent on the well-being of our bodies. For these reasons and many others, we tend to be very aware of and concerned for our bodies.

My wife and I are both runners. We regularly talk about how our recent runs have gone. We also talk a lot about how well our bodies are doing. Daily exercise makes you very aware of the ever-changing state of your body. You become aware of new pains and discomforts. You notice when a run goes well and when you struggle to finish. You pay close attention to how different shoes affect your speed, endurance, and recovery. As with any regular physical activity, you develop areas of soreness and related injuries. You tend to track if particular areas of discomfort are improving or growing worse. When runners get together, a large part of our conversations is about our bodies. We discuss injuries and share treatments we have found to be helpful. We discuss training regiments and how these can improve performance. We discuss shoes and other running-related equipment and how they can help performance, address a chronic injury, or provide comfort.

We pass them by every day on the roads that we travel without much thought or recognition. Little green signs, with white numbers marking the distance in miles from a starting point, blend into the scenery beside the road. These mile marker signs are part of a very long history that stretches back to the first constructed roads. There still stands today beside the roads that the Romans constructed stones engraved numbers indicating the distance from Rome. These stones are called milestones. With this long history, the word "milestone" has found a place in our lexicon not only referring to an object that indicates the distance from a specific point but also to a moment in time that has significance or distinction.

This past weekend I traveled to Columbus, GA, to celebrate a milestone with my dad, who is also named Ben Smith. On Friday, September 1, 1978, my dad started running. From the start, he recorded his running miles and eventually would add them to an Excel file to keep track of his total distance. I was a little boy when he started running, so I do not remember a time when he was not a runner. I do remember that over the years, I would hear him mention different goals that he was striving for. In the early 1980’s he was training to qualify and then run the Boston Marathon. Years later, as his total distance of running approached the distance in miles equal to the distance around the Earth at the equator (24,901 miles), he regularly made announcements as to how close he was getting. When he reached this milestone, he was running with some of his longtime running partners. They stopped and used a disposable camera to capture the moment then continued their run.
