Hi Dave, I am Dave (a lot of us out there). I live in Florida, and I try to keep my rides and runs as early as possible. My ideal temperature is 50, so I have issues here, a lot. Keep hydrated, I need to have air contact with my skin, and sweating is not optional but mandatory. I had someone from south Florida tell me that sweating is how you know you are alive. Don't know about that, but find what works. You may have to go lower intensity for a while. Gawd I miss the high desert!
