My outdoor thermometer said 101 (F) when I left and 108 when I returned. Those numbers reflect direct sunlight not shade conditions. I drank 4 cups of water in 2.7 miles. It felt like the hottest day we've had this summer. Even though my wakeup was 56 and I felt pretty good, I took it easy and stopped several times for a brief rest in the shade. When I got home, my wife asked how it went, and I replied, "I melted".
