Seth Waltz is a runner living in Boston with a running squad about as big as his goals. Seth, or "Common Athlete" not only knows everyone in the Boston running community, but runs with just about all of them on a weekly basis. We talked training, motivation, and how he went from nearly a 4 hour marathon to his goal of lining up in the elite corral at the Boston Marathon... and why that's important to him.
