Headed south on the Pinellas Trail from the inlaws' @ Taylor Lake. Brutal, BRUTAL headwind! Got about 10-1/2 miles in, heading for a long beach loop, when my right knee said, "No, no more of THIS crap!" So I turned around and headed back. Five miles of easy spinning and the knee felt better, so I pushed the pace back. Knee's starting to throb again. Might need to ice it. Meh.
