It’s not so much the heat as the humidity. As someone who runs nearly every day, the weather is an intimate part of my day. In the dead of winter I wonder when the cold will break because I am so tired of running in so many layers. But the summer is so much worse. The heat and the humidity are so oppressive every day of the summer that I can’t wait for fall. And running in fewer clothes won’t solve anything. Any day that is under 70 just feels like a respite. Those have been few and far between the past couple of weeks.
