I finished the fourth week of training with only one missed 5-mile recovery run: I got a stomach virus that made that day a misery, and even on the following day's 11-miler I had a few issues (stomach cramps). The highlight of the week was the 18-mile long run today at 7:47. I got mildly dehydrated and quite exhausted. I thought I was done at mile 15, but managed to rally and put in a strong last mile (7:13). I'm happy I have a rest day tomorrow.
