It's cloudy but rideable. I chose to go to WS. I was hoping the wind would be in the opposite direction, but it wasn't to be. The legs felt pretty good to start. I made it to the end of OTR in good average time. The way out to WS was enjoyable, with the tailwind. Doing 30+ MPH on a few sections. As I was making my way up Highline, I noticed that my power meter wasn't giving a reading, nor the cadence sensor. I ended up pulling over to reset the battery. It didn't help. I hopped back on and then made my way to WS. After reaching the turn-around point, I decided to pull into the local parking lot. I tried swapping batteries from my rear speed sensor to the power meter. It didn't make a difference. My theory is that both batteries are depleted. As, they came from the same set when I replaced them a few rides back. I got back on the road, after that and headed back home. I restarted the GoPro, but the battery complained that it was about depleted. So, I quickly swapped out the battery. From there it was non-stop back. I was trying to keep my focus. Concentration wasn't the greatest, but not too bad either. I was feeling better after reaching Tucker. Up until then, I was doing 15MPH or less, as the headwind had picked up. I made it over the summit, and headed down to OTR. I pulled over for a brief moment to re-fit my leg warmers. OTR was mostly fun and games. From there, I made it over Mariposa and made my way back home. As said, concentration wasn't the greatest today. A few lapses here and there. Fortunately, I was able to keep things under control. Balance and form was good. Ailments, next to none. Gear worked, with the exception of the power and cadence sensors. Nutrition, I drank about 3/4 of my Gatorade. No water. Other notes, no other cyclists today.
