It's very windy and cold out. Perfect day for an indoor workout. I decided to ride with a virtual partner, group C. They're supposed to ride between 1.5 to 2.5 W/kg. I hopped on the trainer and warmed up by soft pedaling for about 5 minutes. After that, I joined the group in progress. I was able to hang with the group. I tried to stay at the front. I was having to ride out of the saddle for a good chunk of the ride. I was having to put over 3 W/kg to keep up and move up in the pack. I don't think went above 155 BPM. Most of the course was flat, so I was riding in my least favorite terrain. It was fun to stay with a big pack. I haven't done that in quite a while. It makes me want to do it again, but I think I'll try and join a group that does more hilly rides. Overall, I felt good. My concentration was pretty good. I was distracted by the group and surroundings. Balance and form was ok, not great. It felt like my left leg was a bit less flexible than the right. Gear worked perfect. Nutrition was good. I had to sit down to wipe sweat and drink. Ailments were mostly hand numbness. Being out of the saddle for many minutes of time was tough on the hands. Other notes, there were about 7,000 riders when I began the ride. About 10,000 riders were on the Paris map. Earlier today the Watopia map was at 11,000 riders! The most I've ever seen, yet!
