Now What?

On Saturday, I ran in the half marathon held at the Baltimore Running Festival. It was an incredible day - perfect weather, lots of happy people and a very successful time. I'd been training for this race for the past 4 1/2 months and essentially, it's all I've been thinking about. And now, well, now I think I've got a case of post-race blues. I've not felt this before because after my first half, back in May, I right away started thinking about Baltimore. This is totally different. I'm wandering around in a fog and don't quite know what to do with myself. My legs were pretty sore after Saturday's race because there were some killer hills but now I'm feeling pretty good so I suppose I could run. Or maybe take up something new like yoga. Or spinning. Hmmm.... Help! What can I do to lift my fog?
