Friday I did my usual run, in 37:18 minutes.

Saturday when I was cleaning the house I tried to move the mattress and I had a sudden lower back pain. It was painful and stiff the rest of the day. In the evening I went for a short walk and did some jogging, to see if running would hurt. It felt fine.

Today I hope to run 9.5 miles. If my back does start to hurt I'll stop right away and walk home.
