I'm gonna feel that tommorrow...

In my continuing effort to lower my run times, I did my first round of "speedwork." For non-runners out there, this consists of an easy run with sprints interspersed throughout it. So, today, I ran 4-miles with a sprint after every half-mile marker (total of 6, as I didn't start in a sprint, nor finished with one). I have to say that I found the run exhausting...but not as much as I thought I would. I feel the soreness it different places than usual...especially the calves (are they really spelled that way?). Anyway, I hope to successfully start improving those times with more speedwork. For now, I'm just going to sit here and wallow in my pain...
