trail 40:11 
Hill repeats; a loop down on the drive that includes one steep hill, then a more gradual switchback back down to the drive and then around on the drive back to the bottom of the hill again. The loop is about 1/2 mile according to Gmaps and the hill about 100 feet of elevation. The plan was to do three, the first one at least 100 paces before walking and then see how I felt. Did 125 paces the seond time around and 150 which is all the way to the top on the third. My pulse was so fast at the top of the third one I couldn't count it. I should wear a heart monitor and see what it is.
Each loop took about 6:20.
Walked home. They are restoring the meadows and it's really getting nice.
Another several hours of yard work. My triceps and hands are sore.
The plan is to convert even more "grass" area to wood-chipped flower beds. It's nice that Philadelphia has a good leaf and tree recycling center and you can go and get car loads of mulch, wood chips and soil for free.
strength & stretching 10:00 
Finally re-inflated my exercise ball. It feel so good to use it for stretching and it makes crunches and push-ups more ... well I'm not sure enjoyable is quite the word I'm looking for, but it makes it easier to make myself do them.
