Week 4 of 9-week training plan (B)

As I mentioned last week, I had a fever and ran a race anyway. I was diagnosed with a sinus infection and started antibiotics this week. I felt bad most of the week so I only ran once this week. My plan was 9 miles today, but at about 7 miles I made a "pit stop". I had a sharp pain in my left knee as I climbed the stairs from my basement treadmill to the main house level where the bathrooms are located. The pain was sharp going back down the stairs too. I resumed jogging, but the pain was very sharp so I stopped jogging at 7.3 miles then walked the remainder of the distance to achieve the goal of 9 miles. Bummer. Hope ice will make it better soon!
