It's the usual fall weather. In the 70's. Cool winds from the South East. Somewhat turbulent. I put in two digs on the risers. I made it to the top of the descent in good time. As I was descending, the wind direction changed about 2 or 3 miles down. I made it to the base, didn't check the time, and headed back up the mountain. The body felt good. I was able to get that HR up without too much effort. I tried to keep the tempo steady. There was another cyclist about 7 minutes ahead of me (We crossed paths as I was descending). The wind was in my favor on the tough parts. My HR was above 150 BPM most of the way up. I caught up to the cyclist as I was about 1 mile from the summit. Concentration was pretty good. Not great. Some dark spots out there, today. Balance and form was good. Ailments, some mild left knee soreness as I was about 10 or 15 minutes from the summit. It never escalated, but was noticeable. I had numb hands as I was nearing the summit. Gear worked flawless. The GoPro had no stoppages. Nutrition was spot on. I went through more than half my Gatorade and a bit of water. Other notes, there were some tourists at the loop monument. No trains to be seen.
