This is my 4th day running. I've been running doubles but only 1 mile at a time until today. The baseline workout is running to the local park and running laps. One lap of the park is 3/8ths of a mile. With the commute from my house, it's a mile. I'm adding a lap or 3/8ths of a mile every Monday and Friday, so adding 3/4 mile per week. Most of my running has been barefoot so far. My rib cage has been feeling pretty good, especially in the afternoon runs. That was what I expected to be the chief limiting factor. I tried running for a few days in mid-June and I had a rib get sore. Other than one little blip, no problems this time. When I'm warmed up, I have been running faster than the usual shuffle.
Also, since I started back to work, I've been napping when I get home. I'm going to continue to do that.
As the distance gets long enough to incorporate specific workouts, I'll start doing those. For instance, I expect to be able to run one hill (repeat) on Thursday. I'm anxious to get back to hills and trails.
My weight is still down at 145 so I didn't balloon up to 150 post-surgery.
So far, so good.
