Did About 1.75 miles

My wife and I began our runs at 10:30 am, going north from the parking lot at 100th South. The temperature was in the mid to high 80s (F), and the shade was less than it would have been if we had gone out earlier, but shade was still available and helpful. I took no rest breaks going out, but I took the two usual breaks on the way back. I carried three bottles of water and only had a small amount of water left when I reached my car. I got pretty tired on the way back. I used my normal 80 seconds/60 seconds ratio of run/walk on the way out, but I reduced the ratios on the way back to give myself more rest between jogs (in addition to the reduction of the ratios, I did more walking and less jogging).
