I am measuring(fitbit) and, like you, I'm getting 4-5 miles a day. I've been really good the past two months. It has been so hot that my secret weapon has been the treadmill; I am so glad that I found out that I can read while I walked...why didn't I try that years ago? My treadmill came from a yard sale years ago, sat in the bedroom collecting clothes for some years and eventually moved out to the garage for a year or two. I started walking seriously this spring...and then the heat hit! Well, I had the brilliant idea of just plugging the treadmill in and walking in the garage with a fan blasting at me. It was really boring so one day I took my kindle out there; after a couple of weeks my husband said, "If you are really serious, let's take this thing back in the house because it is too hot out here!" Now I walk indoors and read...the time goes fast and I'm definitely not bored. I have walked outdoors on cooler days though, just to change it up. Wish we could walk together, Peg.
