To Jacksonville and back from downtown Phoenix. A beautiful light breeze and many a chirping bird kept me in good spirits. Passing cars didn't seem to know what to do with a cyclist on the road. A few other cyclists were out and appeard to be very excited to see a like cyclist. They smiled the chesire smile and waved full arm waves at my passing.My legs felt like lead, I felt the burn on the few small inclines, but I zoomed on the way back, increasing my average by 2 mph. 10:30AM start, 55 min elasped time 18.81 mi, av 15.5 mph no HR data, av approx. 150 bpm
