Calf injury

Well, things were going great till last Saturday, 4/23. Headed out for a 12 mile run and a mile into it, BAM! Calf cramped up on me bad. I tried to stretch it out, but didn't help. I ended up walking home with my head down. Here it its Friday, 4/29 and still can't run. going to the LMT to get the calf worked on, hopefully get back into training next week.
