Yesterday rained and when I got up, it was foggy. I decided to ride in-doors. The setup was very easy. No hiccups. I decided not to use the fan today. Needless to say, I was perspiring quite a bit. But, it wasn't uncomfortable. Just had to use the towel every few minutes. I started brisk. Warmed up for about 7 or 8 minutes before I started to put more power down. I wanted work up a good sweat before Box Hill. I was ready to rock when I got there. I was climbing mostly out of the saddle. I think I sat to down about 3 times, for no more than 5 to 10 seconds at a time. I was doing 150 BPM+ most of the way up. I did a PR by about a second. After that, I cruised for a few minutes, caught my breath and then headed down. I planned on riding at tempo for 1 hour, then cool down. I put in a good push through the tunnel "wall". Nearing around 10 Watts/KG, I think. Fun stuff. The training went quick, thanks to Zwift. I keep thinking how much better it is when I train with this software. Concentration was spot on. No lapses. Balance and form felt good, especially out of the saddle. Gear is working great! Other notes, over 2000 riders today and I won the KOM jersey right about when I was going to call the ride.
