I was reading through Runner's World today and saw a link to this article: Head for the Pool. I might try this for long runs on the weekends as I get back into training this summer. I particularly like the bit of advice to run half on land and half in the pool. Too bad my iPod isn't waterproof.
I woke up today feeling the pleasant soreness from my run yesterday. Nothing too bad just enough to know that I finally worked my muscles. The shin pain seems to be gone (although I haven't done anything long distance to really try it out yet). That may be one benefit from my down time.
