Today was cold, but sunny skies. Winds from the south today and low 40's. I wore the complete kit. Face mask, arms, legs, 2 base layers, full gloves, cap. I felt good from the start. I had a tailwind going out to Keene, so that made somewhat of a bias sensation. I made it to the top of the descent in good time, as usual on a tailwind day. I cruised the downhill, actually having to back off on some sections as the tailwind gave me an extra boost. I think I reached near 42 MPH as I was about 2/3rds down the descent. After reaching the bottom, I adjusted my leg warmers and headed back. As I expected, the headwind proved to be an additional challenge. I did most of the climb in moderate to good tempo. No digs today. I felt good, despite the extra effort required. Concentration was good. Some momentary lapses some gremlins as I was coming back down on WTR. Balance and form felt good. Ailments consisted of some minor lower back pain about 2 miles to the summit. It lingered, but didn't hinder my tempo. Gear is working well. No issues there. I did, however, drop my chain just as I made the right hander on WTR, on the outbound. It took 5 seconds to shift it back onto the chain ring. Other notes, no cyclists or runners today.
