My wake up heart rate was 57, and I felt great. I didn't go running, though, until late afternoon as the sun was setting. The temperature was about 47 (F) when I left home, and I finished the run before it was dark. I wore two layers, a regular technical T-shirt and my wind breaker, and my running shorts. I was actually sweating on my face when I finished the run.
During my first mile, I ran about 2/3 of the mile and walked 1/3. The great thing was that instead of doing less running during the second mile and even less during the third and even less during the fourth miles, I continued to run about 2/3 of each mile. That means I ran about 2 2/3 miles of the 4 miles. That is the most running I've done in one run during the past year. For breakfast I had two glasses of a fruit drink that my wife made. She had one glass. All together, the drink had an apple, a banana, fresh grapes, frozen blueberries, and orange juice. It tasted great. For lunch, about 2:30 pm, I had a slice of a Costco Pepperoni pizza and an ice cream bar with nuts. I knew I couldn't run on that much food, so I waited three hours and then went running. My stomach was fine during the run, and I felt good. The pizza had a lot of calories, but that was my main meal for the day. For supper I had a few nuts.
