First day back to commuting. Converted my '93 TREK 2100 to a commuter. Lights, rack, bag w/ panniers. Nice morning, little fog, 63 F, no wind. 15 Miles. Trip home was hard on me. Seems my lack of exercise and love of food, finally caught up to me. Trip home, 85 F, slight breeze (head wind halfway), tired legs. 13 Miles. I'm back!! My bikes have missed me.
