Day 15 and I have decided to extend my route for a week and see how I get on.

So I am now going further, 30-40min walk but at a bit of a faster pace. Warming up with a slow walk for a couple of hundred yards and then up my incline at a brisker pace, across country at a fairly brisk pace and then back onto the road to warm down before getting home. This is working well for me. My deep breathing is becoming easier and now without any pain involved which is a bonus and my chest is starting to heal. The scar down my sternum is cleaner and looks like a nice clean scar.
