Today is 2 weeks and a day. I started walking 2 weeks ago and today was 5 miles.
In addition, I added jogging today! Jog/walk/jog/walk (I'll be 60 in a couple of weeks). I experienced, what I've heard is a runner's high. I've been home for a half hour and I'm still feeling euphoric. I'm SO glad I quit. I have a feeling I could become addicted to exercise.
