I took the day off, yesterday. Today, the legs feel much better. I'm gaining weight, slowly. Getting back to a more healthy condition. I got out about 8 am. As planned. I was thinking about doing a double. But decided on a single. Perhaps a double no later than next Saturday. The ride went well. I found my optimal zone while climbing. The sensation of bonking never manifested. I didn't feed today, and had no hunger sensations. I think that was the important aspect of this ride. The bike worked great. My concentration was good, for the most part. I wasn't having to coach myself, excessively. Other notes, I saw one other cyclist today. To my surprise, no others.

Edit:

I kept the tempo steady on the climb. No red-lining, no heroics. I kept the tempo going over the top, but no digging.
