Recent (Non-)Training

Having talked about being efficient at running, my calf muscle had started hurting a bit more recently. So, during the time my parents were visiting, I took some time off.
Time off from running per se, anyways - we walked for miles every day, after all.

Yesterday...
04/21/2008 - 01:03.52,3 - 10.21 km - 6'15 min/km - 150 HR avg. - TE 3.5
... I went running again and it seems that there is something amiss, but not much at all. So, I hope it's just a slight strain from running a lot and on variable surfaces, but not a real shin splints-type problem (taking weeks off would take me past the marathons, but of course I also wouldn't go running if I were hurt).
