Yeah, it's pretty much come down to if I am not one of the leaders, I don't ride in a group. However, I have done a few group rides this season, but every year, it gets less and less. Since i know most of the people in the Wednesday group, I know who to avoid! I have never done a large event like the Tour de Tucson; did one Wounded Warrior ride, as it started 3 miles from my house, and the mass start was super scary. Especially, since I certainly did not want to crash into one of the warriors! The one century I did (well, I started it a second time, but that was the one where the people got killed and then later, I crashed into DH, which ended it for us), was terrible at the beginning. People were rude and passing by me in all sorts of terrible positions.
Went to spin today. It was good. Felt hard, but not death defying, if you understand. I need to use Nuun in my bottle, for all indoor stuff where I really work up a sweat. It really seems to help me not feel awful from heat related stuff.
