Delayed for now

I've been running for a week now - just one mile, but each time I increase my speed (From 13:14 to 12:21. I'm happy to be getting faster but oh how I long for those 7-minute-mile days). Now though, I've had to take a couple days off. My body is not allowing me to exercise. Sunday I woke up to my back going into spasms. Today I'm feeling better but my back is still pretty locked up and sore. So I rest. I stretch, I drink lots of water. I heat and ice my back. And I grieve.
