This was a major sufferfest. It was my second race of the day (after the DH Dash 10K). Everything in my upper body felt tight. I got multiple side stitches, and both shoulders started to cramp. Lots of bizarre fatigue effects. My legs weren't dead, but everything else was. Oh well, I still got an age group award even with my slow time (since they go 5 deep in the TN parks series).
