I'm amazed at the pace I've been able to keep on my runs, especially when I've been purposely holding back, relaxing. I've been kind of relearning things I learned back in high school and not long after, about relaxing the upper body, the hands and neck.

Tomorrow morning I'm going to start adding another morning run, short, not more than 15 minutes. Adding frequency without adding much volume. It'll be in the dark, and cold...
