Training non-existent

I am so frustrated. I had great plans for this summer. I was going to finish my first marathon. Yes, you heard me right, a marathon. But I haven't been able to run for months because of my shins. As far as the doctor, coach, and acupuncturist can tell my shin muscles are incredibly tight and that is causing this horrible pain. I am on strict instructions to stop running/walking as soon as it start to hurt. Which means I get in about 10 minutes. **makes an ugly face** I am trying to be okay with this development and focus on some other issues (managing stress mostly), but there are times when I just want to scream and/or cry. Right now it is a combo of the two. Okay, whining over for now :)
