Hello August

I've had a pretty good summer thus far. Now I'm feeling a sore tendon/muscle in my upper left thigh. I first noticed it in the last of a 7 mile training run on Tuesday. I felt it on Wednesday morning so I took a day off. This morning (thursday)I didn't even feel a twinge of pain until late in my 7 mile run. Now that I've cooled down and tightened up, I feel significant pain . Hopefully I can manage to heal and still stay in touch with my training. I've made such progress in the last 6 weeks I hate to loose any edge to my fitness. Got to be intelligent here.
