I can't do a "quick 3 mile run" any more, I can do 3 miles run/walk, but even my run is slow. I usually do the first mile "jogging", then run/walk the other two. I run hard enough to max out respiration. Our pool is open now, our site maintenance guy did a superb job cleaning it, parts had gotten a bit grungy, it looks brand new now. We'll be using it frequently when the weather gets hot. Tuesday we're off to SD and PS.
