Thanks for the advice/suggestions.

Swimming seems to help alleviate most of the calf discomfort. I will take it slow and easy, not build up mileage too quickly. I'm registered for a 9/11 5K in September, and I can already handle the distance. ;-) My goal now is to run for fun and crosstraining. I'm not a competitive type, so it's more smiles than miles for me.

G--I agree w/you about concrete. I ran half- and full marathons back in the olden days, and I always opted for running in the road rather than take that pounding on concrete. Luckily, the MUT is .5 mile from our and there is a macadam nature trail at work!!
