I ran/walked the first half of the workout and part of the way back, and I walked the rest of the way back. Both my wife and I were tired and took it easy. We did our workout in the late afternoon when the temperature was nicer, and we finished just as the sun was going down.
Thursday is going to be a busy day, and I don't know if I will get my workout in. Hopefully, on Saturday I'll go out again.
