The fires are expelling smoke all over the place, in CA. Including Tehachapi. I decided to ride indoors. I chose the France map. I don't remember what the route was called, but I rode for 15.8 miles. I figured it would take about 45 minutes to complete one lap. My estimate was off by only a minute or two. Some additional minutes for the cool-down phase. I had to fiddle around with the receiver dongles, ANT and Logitech Unifyer. Unfortunately, I couldn't get the HR sensor to pair. So, no HR metrics today. I felt good from the start. It took about 7 or 8 minutes to get warmed up. The garage is warmer than the colder days. But, I set the fan to full power. That helped. I was sweating sooner than normal. For the most part, I kept the tempo steady. In and out of the saddle. I was trying to tell myself to refrain from red-lining it, as I'm still recovering from ill effects from the bad air quality. There's a brief climb that had a timed section. I think I got 7th place. I ended up earning the pokadot jersey a few miles from the finish. (The previous winner, logged off and I was the next in line). After finishing the lap, I commenced the cool-down for about 2 or 3 minutes. Concentration was good. I had some music to listen to. It kept me company. Zwift is always an engaging experience. Balance and form was good. Ailments, next to none. Gear worked great. Although, the spare wheel was not calibrated. So, some skip-shifting occured. Nutrition was spot on. I filled my bottle to half way on Gatorade and a full bottle of water. Neither of which I had to consume in its entirety.
