Like many other runners, and, well, humans, my heart has been heavy since Monday. I don't plan on listening to my co-workers and never running a race again. In fact, I plan on participating in the Bay Bridge Run over the Coronado bridge (a tough 4 miler) next month as planned and wearing blue and yellow for Boston. So yesterday when I went out on my run, I put on a race shirt and thought about Boston. It was a short run, but I cried for everyone involved (I'm a crier) and felt peace toward the end.
