Recouperating

My will is still strong, but my body is weak: today was supposed to be Week 3, Day 2, and I was really looking forward to it. However, after Week 3 Day 1 my left shin was starting to feel very tender, and I'm worried about shin splints. It still hurt even after my rest day, so although today was supposed to be an "on" day, I took an extra day of rest. I'm going to work out tomorrow again, and hopefully the extra rest will have helped. I don't want to go on the injured list, and I know that running on concrete is not ideal.
