Did 1.5 miles again

My wife and I went to the Jordan River Parkway again, and she went north so she could check out the new homes being built, and I went south. In the way back I got really dizzy. I don't know if was from lack of food (not much eaten for breakfast and lunch) or was my heart acting up again. The temperature was in the mid 70s (F), so it wasn't heat exhaustion. I got dizzy while walking not while running, actually jogging.
