I had my second Covid-19 vaccine today in the morning. I didn't feel like riding outdoor, so I decided to hop on Zwift. Just as well, being cautious about the vaccine symptoms. Thus far, I feel no different. I chose a map that would allow 30 minutes of riding, before cooldown. The Suki's Playground was perfect. About 11.5 miles. I felt good. The legs were responsive. The route went through part of a quick climb up the castle region. I gave it a go, but my route detoured into a different direction before I was able to reach the summit. I was passing many riders. I was a bit discouraged that I couldn't finish the climb. Otherwise, it would lead to a quick lap time. After reaching the end of the ride, I was wondering where the finish line was and what my time would show. Turns out that I didn't get a lap time. So, no clue where I stood at the end. It was fun to ride with others, though. Concentration was good. I had my music going, Zwift was great! Balance and form was good. Gear worked perfect. Ailments were minimal. Nutrition was good. I had about 2/3rds of my Gatorade, no water. Other notes... I received my new cycling shorts. Pearlizumi Attack Bib Shorts. They are conforming, but the stitching and materials seem a bit sub par compared to the 2018 pair that I have. Will send them back for a lifetime warranty evaluation. Hopefully will receive replacements.
