Shin splints...NOW?

Ever since the Saturday run in Clinton my legs have been so sore. My left calf has been particularly bothersome. I did not exercise yesterday giving myself more time to recover and repair. So, today, I went to the park and started out doing 2:1 intervals...that did not last but one mile because my calves were HURTING like crazy mainly on the inside. Sounds like shin splints which I have not had the entire training period! I am guessing the hills in Clinton are the culprit. I usually run without much of any kind of pain and this is not fun to have legs that hurt as I run. Kristy has run with PF, huge blisters, and others have run with all sorts of pain issues. Well, let me say, I must be a big wimp, because I just ended up walking the rest of my time. I was out there 50 min. which was a struggle at that. I don't like doing minimums and I had intended to wog for at least an hour and start ramping up on my intervals and speed this week. It is disappointing to feel like I am regressing instead of progressing. I must remember that I am still in the game and do not suffer any debilitating injuries thus far...thank you God. So, I will be patient and know that I will bounce back from whatever is going on right now. Oh my gosh, y'all, 22 miles! I only did 18.5 on our last LSD. Will I be able to do it...yes, yes, yes, I can. (fake it 'til you make it)
