Today was unrideable weather. I decided to ride indoors. I did the zwift London Loop. My back is doing well. A bit sore, but not detracting from the workout. I warmed up for 15 minutes and then settled into a tempo. I put most of my effort into the Fox Hill climb. I did moderate tempo everywhere else. I put in two laps. My body felt responsive, no sore muscles. I had a good time. The last kicker in the tunnel is always a treat. I can punch it as hard as possible, and by the time I'm peaked, I've reached the top. I'd say it's a good 50 to 100 meters in length. I was looking at my wattage the last time I pushed over the digger. I was above 9 wpkg. Concentration was good. Some hints of lapses, but overall, spot on. I worked up a good sweat as usual. Gear is working well. I put things together in about 5 minutes without fuss. Form felt good. No ailments to note. Other notes, I found out how to make a u-ee. You press the down arrow key on the keyboard.
