I pay a lot of attention it this. I don't do well in the heat, especially the heat and humidity. And when that happens, we get bad air quality. I have asthma that is totally not an issue for me, but I don't want it to become one. I barely survived a 15 mile ride Tuesday in the heat of the day. It was very humid, the sun was blazing, although it was only 80. Last year I forced myself to ride in hot weather, but mostly started early in the AM. It was just too hot on too many days to do stuff inside.
We just finished 3 hours of rain/thunder and I am getting ready to ride to an appt. I am only doing this on the hottest/most humid day of the year because it's cloudy and the rain cancelled my early AM ride with Hirakukibou.
