I try to keep cool, especially when I feel the heat is hitting me already. Like drink water. I also have a thermos-like water bottle. I try to ride very early to avoid the mid-day heat. We stop in a shady area (ie for breaks) and I remove my helmet to let my head more air to go through. Only thing never done is getting soaked from water fountain....yet. hihi

I've always had issues doing an activity in the sun. That same ride on cloudy day and I'm in heaven!
