Heat sucks. I lived in AZ for 16 years and I don't know how I survived. Well, I never went outside to exercise at all.
Today was 85 and the humidity is starting to edge up. We went out at 3:00 and rode just under 20 and I felt like I had done a century. Tomorrow is going to be 90, but we are doing a beach ride, with a swim/beach stop in the middle. I hope i feel better!
