Update on injuries

I started training for Boston Marathon in early Dec. My hamstring is better but not 100% yet. After a few longer runs (13.6 & 13.8) I developed a gradual pain in my lower back. It seems it comes in after about an hour of running. I think this is biomechanical. I have taken the last week off from running due to another injury to my left foot. My toe next to my big toe is sore. It may be a stress fracture so tomorrow I have a physical and I will ask for an X-ray. It feels better since I have not run since Dec 31.
