Yesterday, I had to wake up very early to get my long run in. I ran 18 miles. My legs felt incredibly heavy. I ran very slow, and there was little fun to be had. I don't know what the problem was. Later that day, we all went hiking and I felt fine.
Today was a recovery run. I ran 11 miles very slowly. this should be my peak week in mileage. We'll see how it goes.
