Went on a solo ride today. The weather was good, although the wind was coming from the South. Over the top of the mountain and on the way down, the wind became turbulent. So, part of the way back I had a tailwind. Especially on the higher gradients. I felt pretty good and was able to hold a good tempo the whole way back. I had 2 slight ailments, a slight cramping in my right calf and tingling in my hands, mostly my right. The calf muscle problem went away after about 10 minutes. The tingling stayed after about 2 miles to go to the summit. Shaking it off helped. Concentration was ok, about an 8. My walkman helped in that area. Balance was a little off. I'm thinking, want to remove the shim on the left shoe to see how that feels. The bike worked flawlessly. The Gopro camera continues to have problems. It shuts off with no indication. I wrote an email to Gopro, will see what they have to say. It should still be well within the warranty period, should I have to get an RMA.
