I Don't Know What to Do

As some of you may know, I was injured last summer with severe IT band issues. And now, with 9 days to go until the Boston Marathon, I fear they are returning.

As much as I love my new shoes, I think I will switch back to my old ones for the remainder of training. Perhaps my new ones don't have the support I need, or perhaps I jumped into such a minimal shoe too soon, or perhaps I did too many hills.

Whatever the reason, the side of my left knee is currently throbbing.

I have one more long run of 12 miles, and a handful of 5 milers. Do I run them? Do I skip them? Do I elliptical them?

Thoughts? Experiences? Advice?
