My wife is fond of saying that she loves summer. She lives in an AC house , drives an AC car and works in an AC office. Last summer on a day they were forecasting 95°. She wanted to take a long ride for breakfast. 82° at 7am. On the way back it was in the 90s. The combination of heat and breakfast was too much. Eating will raise your body temp. She was sick the rest of the day. People that work in the heat know how to manage their body. People that don't may not. Its not just about hydration. It's knowing when to say when. I stood on a blast furnace for 10 years of my life. I learned a lot about heat management in that time. Learning about it on a long ride is no fun. Know your tolerance before you go.
