I'll write more later, but for now, I at least wanted to give a small update: Yesterday, I completed 14 miles. The beginning and end (especially) were rough but I did it. And I'll take it.
The "finish line" I desire is at a full marathon -- specifically, the Marine Corps Marathon. It's a goal I've been working toward, and failing to reach, since 2009. This blog details the ups and downs of this crazy journey of mine.
