DOMS

A little searching has discovered that my stiffness and soreness has a technical name - Delayed Onset Muscle Soreness (DOMS). It's good to see that it's the body's normal way of adjusting to increased exercise.

I don't think I did an adequate warmup for the runs Wednesday or today, resulting in the excess stiffness and soreness. A cold compress and some ASA has helped to make things less painful, and I'm planning on having two rest days before my next run (Tuesday).
