I got out late as usual and wanted to do an easy Zone 2 but once I got out to the main road I started upping the power but the watts seemed low for my efforts. About 11 miles in my left pedal power meter battery died, I thought I had a lot more life in it, I guessed wrong. So I lost all power signal. I was going to pull over and I kept saying the next area with lights o kept going until my lower back started to hurt so bad I could think of nothing else, it was at 17 miles, Changed battery, stretched my back ate 2 tangerines and drank some fluid. Off I went, no shoulder at all and the cats were not giving me much room, I survived that stretch of road and finally turned off to a road not as busy until I got back to Rte 70, big shoulders and rumble strip between cars and me for next 14 miles. My back again started to hurt with a vengeance. I debated cutting ride short but I thought it would only be 2.5 miles shorter, do I kept going to work my legs, breathing and fitness. It was touch holding the pace but the bike felt so smooth it was enjoyable feeling other than my back! My average speed seemed slower than what I was riding at still happy with the ride! The close of that ride adventure and to my next one... See you on the road!
